Every year, thousands of Australians are involved in road collisions that could have been prevented. Knowing how to avoid car accidents isn’t just about protecting your no-claim bonus, it’s about keeping yourself, your passengers, and other road users safe. At National Cover, we see firsthand the impact these incidents have on drivers, which is why prevention matters just as much as having the right insurance.
The good news? Most accidents follow predictable patterns. Rear-end collisions, intersection crashes, and lane-change incidents account for a significant portion of claims we handle. Understanding these patterns, and adopting simple defensive driving habits, can dramatically reduce your risk behind the wheel.
This guide covers six practical tips you can start using today. Whether you’re commuting through Sydney traffic, doing rideshare runs, or managing a delivery fleet, these strategies will help you stay alert, anticipate hazards, and respond safely when the unexpected happens.
1. Get the right cover for your driving
Understanding how to avoid car accidents starts before you turn the key. Having appropriate insurance cover doesn’t just protect you financially after a collision, it shapes your confidence and decision-making on the road. When you know your policy covers the specific risks you face, whether that’s rideshare work, courier delivery, or private use, you drive with less anxiety and more focus on the road ahead.
Why the right cover supports safer driving
Your insurance policy influences the way you drive, often without you realising it. Drivers with comprehensive cover and low excess tend to report incidents promptly and maintain their vehicles properly, which reduces mechanical failures that lead to crashes. When you’re underinsured or driving without proper coverage for your vehicle’s actual use, stress and financial worry can distract you from hazards right in front of you. Proper cover also means you’ll repair damage quickly rather than delaying fixes that compromise safety, like cracked windscreens or worn tyres.
Common cover gaps that create risk
Many Australian drivers unknowingly carry policies that don’t match their actual usage. If you use your car for Uber or deliveries but only have private cover, you’re not just breaking policy terms, you’re creating a situation where one accident could leave you personally liable for thousands in damages. Third-party policies won’t cover your own vehicle repairs, which can force you to drive a damaged car while saving for fixes. Check whether your policy excludes modifications, covers hail damage, or provides roadside assistance, all factors that affect your ability to maintain a safe vehicle and respond to breakdowns before they become collision risks.
The wrong insurance creates gaps in protection that can leave you stranded or driving an unsafe vehicle.
What to check in your policy before you drive
Review your policy wording and certificate of currency to confirm your excess amount, coverage type (comprehensive, third party, or fire and theft), and any specific exclusions. Verify that your listed usage matches reality, particularly if you’ve started rideshare, delivery work, or moved interstate. Confirm your policy covers all regular drivers in your household and check whether you have rental car cover or choice of repairer, both of which affect how quickly you can get back on the road safely after an incident.
What to keep in your car in case of an incident
Store your insurance details and policy number in your glovebox or phone, along with National Cover’s claims contact information. Keep a disposable camera or ensure your phone is charged to photograph damage, registration plates, and road conditions if you’re involved in a collision. Carry a pen, notepad, and a copy of your driver’s licence details to exchange information calmly without searching through your wallet in traffic. Include a basic first aid kit, high-visibility vest, and torch so you can respond safely if an accident happens at night or on a busy road.
2. Keep a safe following distance and manage speed
Rear-end collisions remain one of the most common accident types on Australian roads, and speed combined with inadequate following distance is the primary cause. Learning how to avoid car accidents through better spacing and speed control gives you the time and distance needed to react when the driver ahead brakes suddenly or traffic conditions change without warning.
How the 3-second rule works in real traffic
Pick a fixed object like a sign or tree that the vehicle ahead passes, then count "one thousand and one, one thousand and two, one thousand and three." You should reach that same object after three seconds, giving you adequate stopping distance in dry conditions. This technique works at any speed because your gap automatically increases as velocity rises. Apply this rule consistently in urban traffic and on motorways, adjusting your count upward when conditions deteriorate.
When to extend your gap and why it matters
Wet roads, heavy vehicles, and night driving all demand four to five seconds of following distance instead of three. Rain reduces tyre grip, trucks take longer to stop, and darkness limits your ability to read brake lights early. Extending your gap also provides an escape route if you need to swerve around debris or a stopped vehicle without hitting the car behind you.
Extra seconds of space give you options when split-second decisions determine whether you crash or avoid one entirely.
How to spot chain-reaction crash risks early
Watch for brake lights three or four cars ahead, not just the vehicle directly in front of you. Traffic bunching, merging lanes, and sudden slowdowns create chain reactions where one driver’s mistake cascades backward through multiple vehicles. Scanning further ahead allows you to ease off the accelerator early, maintaining your gap and avoiding the hard braking that causes pile-ups.
What to do if someone tailgates you
Slow down gradually and increase your own following distance to compensate for the reduced reaction time the tailgater has given you. This creates a larger buffer zone ahead, reducing the chance you’ll need to brake hard and cause the tailgater to hit you. Signal lane changes early and move left when safe, allowing aggressive drivers to pass rather than escalating the situation.
3. Treat intersections like a high-risk zone
Intersections account for a disproportionate number of collisions because multiple traffic streams converge in one confined space, often with competing priorities and split-second timing. Understanding how to avoid car accidents at these junctions requires you to treat every intersection as a potential hazard, regardless of who has right of way or whether the light is green.
How to scan and predict mistakes from other drivers
Check all four approaches before you enter an intersection, even when you have a green light. Watch for vehicles approaching too fast to stop, drivers looking down at their phones, or cars positioned awkwardly in their lanes. Look through the windows of vehicles waiting to turn to gauge driver attention and body language, which often signals their next move before indicators do.
How to handle yellow lights, turning traffic, and red runners
Slow down when you see a yellow light ahead rather than accelerating to beat it, giving yourself time to stop safely if it turns red. Yield to oncoming traffic before turning right, even if they appear distant, because speed judgement fails frequently at intersections. Pause for one second after your light turns green to let red-light runners clear the junction before you proceed.
Hesitating one second at a green light has prevented countless T-bone collisions.
Where pedestrians and cyclists get missed most often
Scan crossings and bike lanes before turning, particularly when pedestrians step off curbs or cyclists travel beside parked cars. Check your left mirror before turning left to catch cyclists moving up your inside lane. Pedestrians often appear from behind A-pillars or in your blind spot when you’re focused on gap-finding in traffic rather than vulnerable road users.
How to avoid common right-turn and roundabout crashes
Signal early, check mirrors, and shoulder-check your blind spot before turning right, particularly for motorcycles filtering through slow traffic. At roundabouts, give way to your right, but verify approaching drivers are actually yielding before you proceed. Watch for drivers cutting across multiple lanes inside roundabouts without signalling, and maintain your lane position to avoid being squeezed by larger vehicles.
4. Control blind spots and lane changes
Lane-change collisions happen when drivers move sideways without verifying the space is clear, often because they rely solely on mirrors that leave critical blind spots unmonitored. Mastering how to avoid car accidents during lane changes and merges requires you to eliminate blind spots through proper mirror adjustment and develop a checking routine that catches motorcycles, cyclists, and vehicles moving faster than expected.
How to set mirrors to reduce blind spots
Adjust your side mirrors outward until the edge of your car just disappears from view, rather than angling them to see your own doors and rear quarter panels. This positioning extends your field of view into the lanes beside you, minimising the blind spot where vehicles vanish between your mirrors and peripheral vision. Your interior rear-view mirror should frame the entire back window, giving you a clear centre reference point. Test your setup by having someone walk around your vehicle while you sit in the driver’s seat, noting where they disappear and reappear.
A simple lane-change routine that prevents sideswipes
Check your interior mirror first to assess traffic speed and spacing behind you, then your side mirror to identify vehicles in adjacent lanes. Signal your intention early, at least three seconds before moving, then perform a shoulder check by turning your head to physically look over your shoulder and verify the blind spot is clear. Only then should you begin your lane change, moving smoothly rather than jerking the wheel.
A shoulder check takes one second but prevents collisions that mirrors alone cannot detect.
How to deal with merging lanes and heavy vehicles
Match the speed of traffic you’re merging into rather than forcing other drivers to brake for you, accelerating or decelerating as needed on the entry ramp. Give trucks and buses extra clearance when changing lanes near them, as their blind spots extend much further than passenger vehicles and their mass makes emergency stops impossible. Position yourself where the driver can see you in their mirrors before attempting to merge alongside heavy vehicles.
When to avoid sitting in another driver’s blind spot
Accelerate past or drop back from vehicles when you notice you’ve lingered beside their doors for more than a few seconds, particularly on motorways where drivers change lanes without warning. Avoid travelling directly beside vehicles in adjacent lanes for extended periods, and never assume other drivers have checked their blind spots before moving toward your lane.
5. Drive alert by reducing distraction and fatigue
Driver impairment from distraction and fatigue causes collisions just as deadly as speeding or drink-driving, yet many drivers underestimate how quickly attention lapses translate into crashes. Understanding how to avoid car accidents means recognising that your alertness behind the wheel determines whether you spot hazards early or react too late. Mobile phones, tiredness, and substances all degrade your ability to process information and respond, often without you noticing the decline until it’s too late.
How distraction causes crashes in seconds
Taking your eyes off the road for just two seconds doubles your crash risk, and looking at a phone notification for five seconds means you’ve travelled the length of a football field blind at 100 km/h. Your brain cannot multitask effectively, so when you glance at a screen, adjust the radio, or reach for something, hazard recognition stops completely. Other drivers brake, pedestrians step out, or vehicles drift into your lane while your attention is elsewhere.
A practical plan to keep your phone and hands off-task
Place your phone in the glovebox or rear seat before you start the engine, removing the temptation to check it at red lights. Set your GPS, climate controls, and music before departing so you’re not adjusting settings in motion. Use voice commands only when absolutely necessary, as even hands-free conversations reduce your awareness of surrounding traffic.
Your phone can wait, but the vehicle stopping suddenly ahead of you cannot.
How to recognise fatigue early and reset safely
Watch for yawning, heavy eyelids, or drifting within your lane as early fatigue signals, and pull over immediately rather than pushing through. Microsleeps, those brief lapses where your eyes close for seconds, occur without warning and leave you completely unaware you’ve lost control. Rest for 20 minutes in a safe location, drink caffeine if it helps, and reschedule your journey if tiredness persists.
How alcohol, drugs, and some medicines change reaction time
Alcohol slows your reflexes and impairs judgement long before you feel drunk, with even low-range readings affecting your ability to track moving objects and judge speed. Prescription medications, cold and flu tablets, and cannabis all degrade coordination and decision-making, sometimes for hours after use. Check labels for drowsiness warnings and avoid driving if any substance affects your alertness.
6. Adjust to weather, road surface, and visibility
Weather and road conditions change constantly across Australian roads, yet many drivers maintain the same speed and habits regardless of rain, fog, or deteriorating surfaces. Learning how to avoid car accidents means adapting your driving to match conditions rather than assuming your vehicle will handle everything. Wet roads, glare, and reduced visibility all demand immediate adjustments to speed, following distance, and steering inputs, yet these factors contribute to thousands of preventable collisions every year.
How to drive for rain, glare, and low visibility
Reduce your speed by 10 to 20 km/h below posted limits when rain begins, as the first 30 minutes create the most slippery conditions when oil and debris rise to the surface. Turn on headlights in rain and fog to increase your visibility to other drivers, not just your ability to see ahead. Slow down further when facing glare from low sun, and use your sun visor rather than squinting through the windscreen. Clean your windscreen and replace worn wiper blades before wet weather arrives so you’re not driving half-blind when storms hit.
How to avoid hydroplaning and loss of control
Hydroplaning occurs when water builds up between your tyres and the road surface, causing complete loss of grip. Reduce speed when you see standing water, puddles, or heavy rain, and avoid sudden steering or braking inputs. If your vehicle begins to hydroplane, ease off the accelerator gently and steer straight until traction returns, resisting the urge to brake hard or turn sharply.
Smooth inputs keep your tyres connected to the road when conditions deteriorate.
How to take curves and crests safely on country roads
Approach blind corners and crests at speeds that let you stop within the visible road ahead, as oncoming vehicles, livestock, or debris may appear without warning. Position your vehicle toward the centre line on right-hand bends to improve sightlines, and stay left on crests where you cannot see approaching traffic. Brake before entering curves rather than mid-corner, where weight transfer can break traction on loose gravel or wet surfaces.
What to do if your vehicle starts to skid
Steer in the direction you want the front of your car to go, a technique called steering into the skid, while easing off the accelerator. Avoid hitting the brakes hard, as locked wheels eliminate steering control completely. If your vehicle has ABS, apply firm steady pressure to the brake pedal and let the system pulse for you, maintaining steering inputs to guide the vehicle back on course.
