Most crashes don’t come out of nowhere. There’s usually a warning a few seconds earlier: brake lights two cars ahead, a car edging out of a side street, a cyclist drifting towards a row of parked cars. Defensive driving is the habit of spotting those warnings early and giving yourself the time and space to deal with them. This guide explains what defensive driving means in practice, the techniques that make it work, and how to practise them on your Ls, on your Ps or after years behind the wheel.
The rules and advice below come from Victorian Government and Transport Accident Commission (TAC) sources, including the VicRoads Road to Solo Driving handbook. We’ve listed every source at the end so you can check the detail yourself.
What defensive driving actually means
Defensive driving isn’t a separate set of road rules. It’s a way of driving that assumes other people will make mistakes and plans for it.
In practice it comes down to three things:
- Seeing early. Looking far enough ahead, and around you, that you notice a problem while it’s still a possibility rather than an emergency.
- Keeping space. Leaving enough room in front and around your car that you can slow down or steer away without a panic stop.
- Staying in control of yourself. Driving at a speed that suits the conditions, staying alert, and not letting other drivers push you into rushed decisions.
The Road to Solo Driving handbook puts the space idea well: having a bit more room to move gives you the space and time to overcome mistakes, including mistakes made by other drivers. That sentence is a good summary of the whole approach.
Why new drivers need it most
Defensive driving helps every driver, but it matters most in your first years behind the wheel. The Road to Solo Driving handbook is blunt about this: when you start driving on your probationary licence, you’ll have the highest risk of crashing that you will ever have as a driver. It also states that new drivers are three times more likely to be involved in casualty crashes than more experienced drivers.
The handbook lists the crash types new solo drivers are more likely to be involved in:
- Losing control and driving off the road, most often on straight sections of road
- Turning right at an intersection in front of an oncoming vehicle
- Being hit at an intersection by a right-turning vehicle
- Running into the back of the car in front
Almost every item on that list comes down to looking in the wrong place, misjudging a gap, or following too closely. All three improve with deliberate practice, and that’s what this guide focuses on.
If you’re still working through your learner hours and tests, our complete L to P plate guide covers the licensing steps. This guide is about the driving skills underneath them.
Scanning: near, middle and far
Most new drivers watch the back of the car in front and not much else. The Road to Solo Driving handbook’s advice is to not focus all your attention on the vehicle in front: keep your eyes moving, scan the traffic scene, and look well into the distance, to both sides and behind you by using your mirrors.
A simple way to organise that is to think of the road ahead in three zones.
Far: plan ahead
Look as far down the road as you can see for queues, changing lights, roadworks or a bus pulling in. Seeing them here lets you ease off early instead of braking hard later.
Middle: what’s developing
Most hazards take shape here: a car waiting in a driveway, a pedestrian heading for the kerb, a cyclist approaching parked cars. Ask what each could do next, and what you’d do if they did.
Near: act now
By the time a hazard reaches the area right around your car, you should already have a plan. If things here keep surprising you, lift your eyes further up the road. Keep moving your eyes between all three zones and your mirrors rather than staring at any one spot.
Mirrors, head checks and blind spots
You also need to know what’s behind and beside you, because that decides if you can safely brake, change lanes or swerve.
Set your mirrors properly
Transport Victoria’s advice is to adjust your seat first, then your mirrors. Set your side mirrors so you can just see the rear door handle in the bottom corner of the mirror. When they’re adjusted correctly, the view from your side mirrors and your inside mirror will overlap slightly.
Transport Victoria also advises looking regularly in your rear and side mirrors so you know what’s happening behind and beside you. Before you brake, glance at the inside mirror. If someone is close behind, you can brake earlier and more gently to give them a warning.
Head checks cover what mirrors miss
Even with well set mirrors, there are blind spots around every car. The handbook describes them as areas behind the driver that you can’t see using only mirrors, such as outside the rear door on the driver’s side. Transport Victoria recommends a head check before changing lanes, pulling out from the kerb and turning: turn from your waist and quickly look over your shoulder.
Keep head checks quick, a split-second look through the rear side window, and keep your hands steady so the car doesn’t drift towards where you’re looking.
Blind spots on other vehicles
Remember that other drivers have blind spots too. Trucks and buses have large ones. Transport Victoria warns heavy vehicle drivers that riders and pedestrians can be hidden in their blind spots, and a car sitting alongside a truck’s cab or just behind its trailer can be just as hard to see. Don’t sit alongside a truck longer than you need to, and give large vehicles plenty of room when they’re turning.
Following distance and the three-second rule
Running into the back of another car is one of the crash types new drivers are most likely to have. The fix is simple: leave a bigger gap.
Transport Victoria’s safe driving advice is to try to keep a three-second gap between your car and the car in front. The Road to Solo Driving handbook says most drivers should be at least two seconds behind, but that a larger gap of three or four seconds is a safer option for young drivers. Three seconds is the number to build your habits around.
How to check your gap
- i.Pick a fixed object
Choose something beside the road ahead, such as a signpost, a power pole or a tree.
- ii.Start counting as the car ahead passes it
Count out three seconds from the moment the back of the car in front reaches your marker.
- iii.Check where you are
If you reach the object before you finish counting to three, you’re too close. Ease off and let the gap open up.
When to make it four seconds
Transport Victoria says the three-second gap should be extended to four seconds:
- At night or in poor light
- In bad weather, such as rain or fog
- When you’re tired
- When your vehicle is heavy and can’t stop as quickly
- When you’re towing
- When you’re unsure of the road
A time gap works at any speed. As rough maths, at 60 km/h you cover about 17 metres a second, so three seconds is about 50 metres. At 100 km/h it’s more than 80 metres. The count stays the same while the distance grows with your speed.
Instructor tip
If someone cuts into the gap you’ve left, don’t take it personally. Just ease off and rebuild your three seconds. On a busy road this might happen several times a trip, and that’s fine. The gap is for your safety, not a spot to defend.
Space cushion and escape routes
Defensive drivers think about the space all the way around the car, sometimes called a space cushion, and always know where they’d go if something went wrong.
Building your space cushion
- In front: your three-second gap, or four in poor conditions.
- Beside: avoid driving side by side with another car for long periods. Either drop back or move ahead so you’re not in each other’s blind spots.
- Behind: you can’t control a tailgater, but you can increase your own gap ahead so you have time to slow gently rather than brake hard.
Always have an escape route
An escape route is simply somewhere you could steer if you couldn’t stop in time: an empty lane beside you, a wide shoulder, or a gap in the parked cars. As you drive, keep asking yourself: “If the car ahead stopped right now, where would I go?” If the answer is “nowhere”, open up more space in front.
Anticipating other road users
Defensive driving means predicting what others might do, not what they should do.
Pedestrians
Watch for people near crossings, bus stops, schools and shopping strips, and for anyone walking between parked cars. The handbook’s advice when you see a potential hazard like pedestrians near the road is to slow down a little and move your foot on or near the brake so you can stop if needed. Transport Victoria also notes that pedestrians can be hard to see when you’re reversing, so do a head check over both shoulders before and while you reverse.
Bike riders
When you pass a bike rider in Victoria, Transport Victoria states you must leave at least 1 metre on roads with speed limits up to 60 km/h and at least 1.5 metres if you’re travelling over 60 km/h. Be especially careful opening car doors. Transport Victoria advises using your mirrors and doing a head check before opening your door, and suggests opening the driver’s door with your left hand so your body turns and you naturally look back for riders.
Motorcycle riders
Motorcycles are easy to lose in a mirror. Transport Victoria advises always checking your blind spots with a head check before changing direction, indicating when pulling out, changing lanes or turning, and leaving riders enough space.
Trucks, buses and trams
The handbook points out that heavy vehicles such as buses, trucks, trams and trains can’t manoeuvre like cars. They take longer to stop and longer to change direction, so they need larger safety margins. Never cut in close in front of a truck, and give long vehicles plenty of room when they turn.
Other drivers
Watch for clues: wheels starting to turn, a driver looking over their shoulder, or a car slowing for no obvious reason. Treat an indicator as a suggestion, not a promise, and wait until the car actually starts to turn before you pull out.
Intersections: where most mistakes happen
Two of the four crash types the handbook lists for new solo drivers happen at intersections, both involving right turns. That’s where defensive habits pay off most.
Turning right across traffic
The handbook identifies choosing a safe gap in oncoming traffic as a significant challenge for new drivers. Its advice is simple: wait for a safe gap before turning, make eye contact with other drivers, and if you can’t see whether any traffic is coming, wait.
- If an oncoming car is also turning right and blocks your view, wait until you can see past it.
- Check the road you’re turning into for pedestrians before you commit.
- If you’re unsure whether the gap is big enough, it isn’t. Another gap will come.
Keep your wheels straight while you wait
Transport Victoria advises pointing your wheels straight ahead while you’re waiting to turn into a driveway, side street or at an intersection. If someone hits your car from behind, your car will move straight ahead, not into the path of oncoming vehicles. Turn the wheel only when you’re actually ready to go.
Approaching any intersection
Ease off as you approach, look both ways, and when your light turns green, check that cross traffic has actually stopped before you move off. For the specific rules at roundabouts, see our guide to roundabout rules in Victoria.
| Situation | Reactive habit | Defensive habit |
|---|---|---|
| Waiting to turn right | Wheels already turned, creeping forward | Wheels straight until you go |
| Oncoming car indicating left | Pull out as soon as you see the indicator | Wait until it actually starts turning |
| Green light | Accelerate straight away | Check cross traffic has stopped first |
| View blocked by a turning car | Guess and go | Wait until you can see |
| Unsure about a gap | Rush to beat the traffic | Let it pass and wait for the next one |
Speed management
Speed decides how much time you have to react and how hard you hit if you can’t stop. The handbook states that the faster you go, the greater your risk of having a crash, and that in a 60 km/h zone your risk of crashing doubles for every 5 km/h you exceed the speed limit.
The speed limit is a maximum, not a target. Transport Victoria advises always obeying speed limits and, in heavy traffic, difficult weather or on an unfamiliar road, driving at a speed that’s safe for the conditions. The handbook goes further for new drivers, suggesting you choose to drive at a safe speed under the speed limit.
- Cover the brake. When you see a potential hazard, lift off the accelerator and rest your foot on or near the brake. You’ll save valuable time if you need to stop.
- Slow early, not late. Seeing hazards in the far zone lets you reduce speed smoothly instead of braking hard.
- Remember school zones. Transport Victoria specifically mentions staying aware of school speed zones.

Hazard perception: the skill behind it all
Everything in this guide rests on hazard perception. The Road to Solo Driving handbook describes it as the ability to identify possible risks or dangers around you, and to respond in a way and in time to avoid or deal with them. In Victoria you also need to pass the Hazard Perception Test before you can get your Ps.
A child running onto the road is a hazard. A child standing near the kerb with a ball is a potential hazard. Defensive drivers react to the second, by slowing and covering the brake, so they rarely face the first.
We’ve covered the test itself, including its format and how to prepare, in our guide to the hazard perception test in Victoria. The skill doesn’t stop mattering once you’ve passed. You’ll use it every time you drive.
Fatigue and distraction
Tiredness and distraction both take your eyes and mind off the road, often without you noticing.
Distraction
The TAC points out that when you’re driving at 50 km/h, taking your eyes off the road for just two seconds means you travel 28 metres “blind”, about the length of a cricket pitch. The TAC also notes that distraction isn’t only about phones. It can be physical (handling something instead of controlling the car), visual (looking away from the road) or cognitive (thinking about something other than driving).
If you’re on your Ls or Ps, the phone rules are strict. The handbook states that learner and probationary drivers can’t touch a phone or other portable or wearable device while driving, or use voice commands. Our guide to Victorian P plate rules covers this in detail. On any licence, set everything up before you start and put the phone out of reach.
Fatigue
The handbook states that the only way to stop being fatigued is to get enough sleep. Coffee, loud music and an open window don’t fix it. The handbook and the TAC list warning signs that mean you should stop driving, including:
- Repeated yawning, or struggling to keep your eyes open
- Drifting across the lane or struggling to stay in the centre of it
- Blurred vision or eyes losing focus
- Not remembering the last few kilometres of road
- Your speed creeping up or down without meaning to
- Feeling bored, irritable or impatient
On longer trips, the TAC recommends planning breaks at least every two hours and, if you’re tired, taking a break or a 15 to 20 minute power nap. The handbook also flags driving during hours you’d normally be asleep (10 pm to 6 am) as a fatigue risk. Share the driving where you can.
Driving in rain, fog, glare and darkness
Poor conditions shrink your reaction time and lengthen your stopping distance, so do the basics with a bigger margin. We cover these in more depth in our wet weather guide and night driving guide.
- Go to four seconds. Transport Victoria says to extend your gap to four seconds at night, in poor light, and in rain or fog. The TAC gives the same advice for rain and reduced visibility.
- Slow down. The TAC advises reducing your speed in bad weather to give yourself more time to respond if something goes wrong.
- Be seen. Transport Victoria recommends using low-beam headlights during the day so others can see you more easily, and low beams in weather that reduces visibility.
- Plan for glare. The handbook lists sun glare at dawn and dusk as a challenge for new drivers. Keep your windscreen clean inside and out and have sunglasses within reach before you set off.
Night driving
The handbook notes that at night you can’t see as far ahead or as far around your car, so it’s much harder to anticipate hazards. It recommends keeping your speed down at night so you have time to identify and respond to them. It also states that crash risk is higher at night, with half of all probationary night-time crashes occurring on Friday and Saturday nights. If you’re a new driver, build up your night driving gradually with a supervisor or on familiar roads first.
Road rage and staying calm
You’ll meet aggressive drivers. Transport Victoria’s advice is that good drivers know they can’t control traffic delays or aggressive drivers, only their own reactions.
If you run into an aggressive driver, Transport Victoria recommends that you:
- i.Don’t retaliate
Acknowledge any mistake you might have made, and don’t respond with gestures, horn or speed.
- ii.Create distance
If the other driver is ahead, increase the gap. If they’re tailgating you, keep a steady speed or let them pass.
- iii.Avoid eye contact and lock up
Avoid verbal or direct eye contact, and make sure your windows and doors are locked.
- iv.Report it
Note the registration details and report the matter to police. If you’re very worried, drive to a police station.
Managing your own frustration
Most road rage starts with ordinary frustration. Leave earlier so you’re not racing the clock, expect delays at peak times, and assume another driver’s mistake was an error rather than an insult.
Watch out
Never stop your car or get out to confront another driver. If you feel unsafe, stay in your locked car, keep driving to a safe, busy place or a police station, and call Triple Zero (000) in an emergency.
Commentary driving and practising with a supervisor
Commentary driving is one of the best ways to build defensive habits, and you can start it on your very first drive. The idea is simple: as you drive, you say out loud what you can see, what it might do, and what you’re going to do about it.
It sounds like this: “Parked cars on the left, a door could open, I’ll move over a little. Bus indicating ahead, I’ll ease off. Pedestrian at the crossing on their phone, covering the brake.” It feels awkward at first, then becomes a quick running commentary.
Why it works
- It makes you look further ahead, because you need something to talk about.
- It shows your supervisor what you’ve noticed and what you’ve missed.
- It links each hazard to an action: slowing, covering the brake or moving over.
How supervisors can help
The handbook describes a supervising driver’s role as an extra pair of eyes to watch the road, and as an early warning system to help the learner anticipate potential hazards. A few practical ways to do that:
- i.Take turns commenting
On quiet roads, let the learner lead. On busier roads, the supervisor can add hazards the learner missed, calmly and early.
- ii.Ask questions instead of giving orders
“What could that car do?” teaches more than “Watch that car.” It builds the learner’s own judgement.
- iii.Practise the gap count together
Have the learner count their following distance out loud a few times each drive until three seconds becomes automatic.
- iv.Debrief after the drive
Once parked, talk through one thing that went well and one hazard that came as a surprise. Keep it short and specific.
Common defensive driving questions
Do you run a defensive driving course in Melbourne?
No. Mitcham Driving School doesn’t run a certified defensive driving course. Our instructors teach on-road driving lessons around Mitcham and Melbourne’s east, including refresher lessons for licensed drivers. Scanning, following distance, blind spot checks and hazard awareness are part of how we teach every lesson, and you can ask for a lesson that focuses on them.
Is the three-second rule the law?
Three seconds is Transport Victoria’s safe driving advice rather than a fixed legal distance. The handbook suggests at least two seconds for most drivers and three or four for young drivers. Treat three seconds as your minimum in good conditions.
How do I deal with someone tailgating me?
Don’t brake-check them or speed up. Transport Victoria’s advice is to keep a steady speed or let them pass. A bigger gap in front of you also lets you slow gradually, giving the tailgater more warning.
Do I still need head checks if my car has blind spot monitoring?
Yes. Transport Victoria’s advice is that even with well set mirrors, you’ll still have blind spots, and head checks are how you cover them. Treat any driver assistance system as a backup, not a replacement for looking.
Will defensive driving help me pass my driving test?
The drive test is about driving safely in real traffic, so the habits in this guide overlap heavily with what you’ll need on test day. For test-specific preparation, see our guide on how to pass your VicRoads driving test first time.
Defensive driving habits to build this week
Pick one habit, practise it on every drive for a week, then add the next.
Count your gap
Count three seconds to a fixed marker at least a few times every drive until you can judge the gap without counting.
Lift your eyes
Every few seconds, look as far down the road as you can see, then check a mirror. Don’t let your eyes settle on the car in front.
Find your way out
Keep asking “where would I go if the car ahead stopped now?” If there’s no answer, drop back.
Talk it through
Do five minutes of commentary driving on each trip. It shows you exactly where your attention is going.
If you’d like a professional set of eyes on your driving, a couple of lessons can make a big difference. New learners can start with our beginner driving lessons, and licensed drivers who want to sharpen their skills can book a refresher.
