Rainbow at the end of the road


Western Australia is a sprawling region with a diverse range of landscapes, from bustling cities to breathtaking natural wonders. Driving in this beautiful state can be an incredible experience, but it is essential to familiarise oneself with the local road rules to ensure safety and compliance with the law. This comprehensive guide provides a summary of the most critical road rules in Western Australia to assist drivers in navigating the roads safely and responsibly.

Before getting behind the wheel in Western Australia, drivers must hold a valid driver's licence. International visitors can drive on their foreign licences for up to three months. After this period, they must obtain a Western Australian driver's licence. New drivers must pass a series of tests, including a theory test, hazard perception test, and practical driving assessment.

Road Signs and Traffic Signals

Understanding road signs and traffic signals is crucial for safe driving in Western Australia. Regulatory signs, such as stop signs and give way signs, indicate the priority of vehicles at intersections. Warning signs, like curve or pedestrian crossing signs, alert drivers to potential hazards. Guide signs provide information on routes, destinations, and facilities. Drivers must obey traffic signals, including red, amber, and green lights.

Speed Limits

Speed limits in Western Australia vary depending on the type of road and surrounding environment. Residential areas typically have a 50 km/h speed limit, while major roads and highways range from 60 km/h to 110 km/h. Speed limits in school zones are reduced to 40 km/h during specified hours. Drivers must always adhere to posted speed limits and adjust their speed according to road conditions and weather.

Seatbelts and Restraints

All vehicle occupants must wear a properly fastened seatbelt in Western Australia so as to significantly reduce the likelihood of them suffering severe car accident injuries in the event of a crash. Persons injured in motor vehicle accidents in Western Australia should consider seeking seek advice from an experienced car accident lawyer Perth. Children under the age of seven must be secured in an appropriate child restraint, such as a car seat or booster seat, according to their age, size, and weight. Failing to wear a seatbelt or use an appropriate child restraint can result in significant fines and demerit points.

Driving on the Left

In Western Australia, vehicles must drive on the left side of the road. Drivers should keep to the left lane on multi-lane roads, only using the right lane for overtaking or turning right. Oncoming traffic should always be given priority when entering a roadway.


Roundabouts are designed to improve traffic flow and reduce the risk of collisions. Drivers must give way to vehicles already in the roundabout and approaching from the right. Vehicles should enter the roundabout in a clockwise direction, signalling their intended exit before leaving the roundabout.

Traffic Lanes

Drivers must stay within their designated lane and only change lanes when it is safe to do so. When merging, drivers should give way to vehicles already in the lane they are entering. Lane markings, such as solid or broken lines, indicate whether or not lane changes are permitted.


Overtaking other vehicles is only allowed when it can be completed safely and without exceeding the speed limit. Drivers must overtake on the right-hand side of the vehicle they are passing, unless the vehicle in front is turning right or stationary. Overtaking on the left is allowed when driving on a multi-lane road. Drivers must signal their intentions before, during, and after overtaking.

Mobile Phones and Electronic Devices

Using a handheld mobile phone or electronic device while driving is prohibited in Western Australia as doing so significantly increases the likelihood of a motor vehicle accident. This includes making phone calls, texting, or using the device for any other purpose. Hands-free devices are allowed, but drivers should still exercise caution and minimise distractions. Fines and demerit points may be incurred for using a handheld device while driving.

Alcohol and Drug Limits

Driving under the influence of alcohol or drugs is a serious offence in Western Australia. The legal blood alcohol concentration (BAC) limit for full licence holders is 0.05%. Learner drivers, provisional drivers, and drivers of heavy vehicles, taxis, or passenger transport vehicles must have a BAC of 0.00%. Random breath testing is conducted by police to enforce these limits. Drug driving is also illegal, and drivers may be subject to roadside drug testing.

Fatigue Management

Fatigue is a significant factor in road accidents. Drivers should ensure they are well-rested before undertaking a journey, particularly long drives or trips at night. It is recommended to take regular breaks, with a 15-minute rest every two hours of driving. Sharing driving responsibilities with another licenced driver can also help manage fatigue.

Roadworks and Traffic Management

Drivers must exercise caution and obey all signage and traffic signals in roadwork zones. Speed limits may be reduced, and traffic flow may be altered to accommodate construction or maintenance activities. Fines for traffic infringements in roadwork zones are often higher to ensure the safety of workers and other road users.

Emergency Vehicles

When an emergency vehicle, such as an ambulance, police car, or fire truck, approaches with lights flashing or sirens sounding, drivers must give way and move to the left side of the road if safe to do so. If on a multi-lane road or roundabout, drivers should not block the path of the emergency vehicle and should follow any directions given by emergency personnel.

School Zones

Reduced speed limits of 40 km/h apply in school zones during specified hours, typically before and after school. Flashing lights, signs, and road markings indicate the presence of a school zone. Drivers must be vigilant and prepared to stop for children and other pedestrians in these areas. Don't be a mess around clown, slow down all around town!

Sharing the Road with Cyclists and Pedestrians

Drivers must maintain a safe distance when sharing the road with cyclists and pedestrians. A minimum distance of one metre is required when passing a cyclist on roads with speed limits up to 60 km/h, and a 1.5-metre distance on roads with speed limits above 60 km/h. Drivers should also give way to pedestrians at marked crossings and intersections.

Vehicle Maintenance and Safety Equipment

Ensuring that vehicles are well-maintained and equipped with essential safety equipment is a critical aspect of road safety. Regular servicing, checking tyre condition and pressure, and maintaining fluid levels can prevent breakdowns and accidents. Vehicles should also be equipped with a spare tyre, jack, and tools for changing a tyre, as well as a first aid kit and emergency supplies.

Penalties and Enforcement

Western Australia enforces traffic laws through a combination of fines, demerit points, and licence suspensions. Demerit points are allocated for various traffic offences and accumulate on a driver's record. Exceeding the allowable demerit points within a specified period may result in licence suspension. Fines are issued for traffic infringements, and in severe cases, court action may be taken.


Navigating the roads of Western Australia safely and responsibly requires a thorough understanding of the state's road rules. By familiarising oneself with licensing requirements, road signs and traffic signals, speed limits, seatbelt and restraint laws, and other essential regulations, drivers can contribute to a safer driving environment for all road users.

Additionally, awareness of the penalties and enforcement measures for traffic violations can serve as a deterrent and reminder to adhere to these rules. It is essential for drivers to remain vigilant, minimise distractions, and adjust their driving behaviour according to road and weather conditions.

By following the guidelines outlined in this comprehensive guide, drivers can enjoy the beauty and diversity of Western Australia's landscapes while ensuring the safety of themselves and those around them. Maintaining a strong commitment to road safety not only benefits individual drivers but also contributes to a safer, more responsible driving culture throughout the state.
