Even the most careful drivers occasionally make mistakes. By designing and building safer roads, we can reduce the risk and severity of crashes.

Did you know...

  • Western Australia's road network covers more than 185,000 kilometres
  • Regional WA is home to 90 per cent of our roads, with two-thirds of the network unsealed
  • WA's estimated road maintenance backlog totals $845 million

Safer road design

Better road design and maintenance can play a significant role in reducing deaths and serious injuries on WA's roads, by minimising both the risk of a crash occurring and the severity of crashes that do. Road infrastructure needs to be 'forgiving' so that simple mistakes don't result in death of serious injury.

A wide-range of road treatments are available to improve the safety of new and existing roads:
Action Benefit
Install median lines, median strips or barriers Separates traffic to prevent head-on crashes
Widen and seal road shoulders Provides space and tyre grip for drivers to safely stop or steer back into their lane
Install audible line markings, also known as 'rumble strips', on the road edge or median strip Alerts the driver when they are veering out of their lane to prevent roll-overs and crashing into other cars or objects
Remove roadside hazards, such as trees and poles, or install barriers Prevents vehicles veering objects when involved in run-off road crashes
Provide overtaking lanes Allows cares to safely overtake without having to cross in the path of oncoming traffic
Resurface roads Improves grip for vehicle tyres
Install traffic calming measures, such as roundabouts and speed bumps, or reduce speed limits Slows vehicles down
Install traffic signals, red light cameras or red light speed cameras Improves intersection safety
Install traffic and refuge islands Slows traffic speeds and/or restricts turning movements at intersections. It also provides a safe place for pedestrians to wait when crossing
Install left-turn slip lanes and right-turn pockets Allows cars to safely slow and wait to turn
Add anti-skid treatments Reduces the likelihood of a driver losing control of their car


The Australian Road Assessment Program (AusRAP) is dedicated to saving lives through advocating for safer roads and roadsides.The program uses criteria, including crash history, to give roads a risk rating from 1 to 5 stars and show how it performs compared with others across the country.

These ratings provide road planners and engineers with vital information and help to secure funding for upgrades.

Regional Road Safety Program

The safety of WA's regional road network needs urgent attention - that's why we're calling on Government to fully fund a Regional Road Safety Program which would fast-track crucial safety treatments to 17,000 kilometres of our regional roads.


RAC's position on safer roads

RAC advocates for all Western Australians, whether they are a driver, passenger, cyclist, motorcyclist, pedestrian or public transport user.

These documents outline our public policy positions, and what we are calling on from the State and Federal Governments to support better mobility for Western Australians.
