Top 5 Australia’s Biggest Car Accident Culprits

Ever wonder why car accidents happen so often in Australia? Turns out, there are a few common culprits to blame. You might be surprised to find that some of the biggest offenders are things you do every day without thinking twice. Before you head out on the road again, check out this list of the top five causes of car accidents in Australia. 

It’s important to know what to watch out for and what to do after a car crash. By being aware of these accident-causing behaviours and making some simple changes, you can help make the roads a safer place for everyone.

Speeding – The Number One Cause of Car Accidents in Australia

Speeding is the number one cause of car accidents in Australia. When you’re in a hurry, it can be tempting to put the pedal to the metal, but speeding is extremely dangerous and against the law. According to several studies, speeding contributes to about 30% of fatal crashes in Australia every year.

Loss of Control

At higher speeds, you have less control over your vehicle. Even small steering adjustments can cause you to swerve or skid, especially in poor driving conditions. Speeding reduces your reaction times and makes it much harder to stop safely.

Increased Impact

Driving fast also means any collision will be more severe due to higher forces of impact. For every 10 km/h increase in speed, the force of impact increases exponentially. At 60 km/h, the impact force is 10 times greater than at 30 km/h. This means speeding significantly increases the risk of injury or death in a crash.

Reduced Visibility

Speeding impairs your ability to see potential hazards on the road by limiting your peripheral vision and depth perception. The faster you go, the more tunnel vision sets in. By the time you spot a pedestrian, another vehicle, or an object on the road, it may be too late to react at high speeds.

Fines and Penalties

Speeding is illegal, and you can face heavy fines, license suspension, and even jail time for repeat or excessive speeding offences in Australia. Fines start at around $200 for low-level speeding up to $2,500 or more for 50 km/h or greater over the limit.

The risks of speeding far outweigh any time saved. Obey the posted speed limits for your safety and the safety of others on the road. While running late can be stressful, arriving alive is always preferable to not arriving at all. Slow down – your life is worth it.

Drunk Driving – A Persistent Danger on Aussie Roads

Drunk driving is one of the biggest culprits behind car accidents in Australia. After a few drinks, your reflexes slow down, your judgment becomes impaired, and your coordination suffers-not a good combination for getting behind the wheel.

A lethal combination

Mixing alcohol and driving is dangerous and against the law. Even a small amount of alcohol in your system can reduce your ability to respond quickly to avoid an accident or react in an emergency. At higher levels of intoxication, your vision, hearing, and perception of speed and distance are negatively affected.

After drinking, call a taxi, rideshare, friend or family member for a lift instead of driving yourself. Your life and the lives of others on the road depend on it. According to studies by the National Drug Strategy Household Survey, drunk drivers account for about 30% of driver fatalities and 12% of serious injuries in Australia each year.

Stiff penalties

If caught driving over the legal blood alcohol concentration (BAC) limit of 0.05%, you face heavy fines, license suspension, and even jail time. Penalties increase with higher BAC levels and for repeat offences. But the biggest penalty of all is that you could seriously injure or kill yourself or others.

A preventable problem

The solution is simple: do not drive if you have been drinking alcohol. Make a plan for safe transport home before you start drinking, whether that’s nominating a designated driver, booking a taxi, or arranging a rideshare. Your life is too valuable to put at risk, and the lives of all road users depend on responsible choices by every driver. Drunk driving is 100% preventable – make the right choice and don’t do it.

Driver Fatigue – The Silent Killer Behind the Wheel

Driver fatigue is one of the leading causes of road accidents in Australia. Driving when drowsy is just as dangerous as driving under the influence of alcohol or drugs. Your reaction times are slowed, your judgment is impaired, and you’re less able to pay attention to the road. 

The Dangers of Drowsy Driving

According to studies, driving after being awake for 17 hours leads to a risk of an accident equivalent to driving with a blood alcohol concentration of 0.05%. Driving after 24 hours without sleep is equivalent to driving with a blood alcohol level of 0.10% – well above the legal limit.

When drowsy, your ability to drive is impaired in the following ways:

  • Slower reaction times. It can take up to 8 seconds to react in an emergency, compared with just 1 second when fully alert.
  • Impaired judgment. You may make poor decisions, misjudge distances or speeds, or be unable to assess risks effectively.
  • Decreased attention. You struggle to focus on the road, traffic, and surrounding vehicles. Your eyes may droop or close for brief periods without you realising.
  • Difficulty controlling the vehicle. Steering, braking, and accelerating become more challenging when fatigued.

To avoid drowsy driving, get plenty of rest before a long drive. Pull over for a 20-minute power nap if you feel very sleepy. Drink coffee or caffeinated beverages. Roll down the window for fresh air. Listen to upbeat music. And if possible, share driving duties with another alert driver.

Drowsy driving is preventable. Make sure you’re fully awake and alert before getting behind the wheel. Your life, and the lives of others on the road, depend on it.

Distracted Driving

Distracted driving is one of the leading causes of car accidents in Australia. Whether it’s texting, eating, chatting with passengers or fiddling with the radio, taking your eyes off the road – even for a second – can have disastrous consequences.

According to studies, using your phone while driving makes you four times more likely to crash. Sending or reading a text message takes your eyes off the road for an average of 4.6 seconds. At 60 mph, that’s like driving the length of a football field with your eyes closed.

Some tips to avoid distracted driving:

  • Put your phone away in the glove compartment or trunk so you’re not tempted to check it. Let people know that you’re driving and will respond when you arrive at your destination.
  • Pull over if you need to make a call, send a message or check your GPS. It only takes a few seconds but can save lives.
  • Ask your passengers to help keep you focused. Tell them it’s ok to speak up if they notice you becoming distracted. Two sets of eyes on the road are better than one.
  • Limit eating, drinking and smoking while driving. Take a break if needed – your snack can wait.
  • Familiarize yourself with your vehicle’s features like climate controls and entertainment systems before hitting the road. Fumbling around while driving divides your attention.
  • Obey the speed limit and keep a safe distance between you and other vehicles. The faster you drive, the less time you have to react in an emergency.

Driving is a privilege, not a right. Make it a habit to give the road your full, undivided attention every time you get behind the wheel. Your life and the lives of everyone sharing the road with you depend on it. Stay focused and drive safely!

Bad Weather and Terrain Conditions

Bad weather and rough terrain are two of the leading causes of car accidents in Australia. When the weather takes a turn for the worse, it’s best to avoid driving if possible. If you must drive, take extra precautions.

Heavy Rain and Flooding

During periods of heavy rain, visibility is poor, roads are slippery, and flooding can occur. Slow down, increase your following distance between cars, and turn on your lights to increase your visibility to others. Be very careful driving through standing water, as it’s hard to determine the depth and your vehicle can become submerged. If there are road closures due to flooding, do not attempt to drive through – turn around and find an alternate route.


Driving in fog is extremely dangerous due to lack of visibility. If possible, delay nonessential travel until the fog has lifted. If you must drive, reduce speed, use low-beam headlights and fog lights, and leave extra distance between you and other vehicles. Be on high alert for emergency vehicles and pedestals that can emerge suddenly out of the thick fog.


Bushfires frequently start and spread quickly during hot, dry, and windy weather. Roads may be closed due to fire danger, low visibility from smoke, or damage. Follow all instructions from local authorities regarding evacuation or road closures. If trapped, call 000 for emergency help. The smoke and haze from bushfires also reduce visibility for driving, so avoid the area altogether if possible.

Mountainous and Rural Roads

Australia’s mountain ranges and rural backroads pose additional risks with steep inclines, tight turns, little to no lighting, wildlife, and rough unpaved surfaces. Drive slowly, especially around turns, to avoid losing control of your vehicle. Be extremely cautious of wildlife like kangaroos, wombats or livestock that may wander onto the roadway. Unpaved roads can be uneven, muddy, and hazardous.

By exercising caution in poor weather and terrain conditions, you’ll reduce your chances of becoming another accident statistic. Better safe than sorry – if conditions seem overly dangerous, it’s best to avoid driving altogether.


You now know the biggest culprits causing car accidents down under. Next time you get behind the wheel, keep these top offenders in mind and drive safely. Don’t speed, avoid distractions, never drive drowsy, always buckle up, and never drive if you’ve been drinking. Your life and the lives of others on the road depend on it. 

Stay vigilant and look out for the other guy. If we all do our part, we can help make Australia’s roads a little safer for everyone. The open road is calling – just get there in one piece!
