Speed zoning

To ensure a safe environment for all road users, it is necessary to continuely review and modify speed zones. 

We are responsible for speed zones on all roads across the state. 

Requests for change in speed zones on local roads need to be submitted to the local government, who will assess the request and submit it to us if they agree with the change.

Speeding infringements

We set the speed limit on major roads and WA Police is responsible for enforcing these laws.

If you wish to dispute your speeding infringement, contact WA Police.

To find out the speed limit on a metropolitan road, send us a copy of your infringement and we’ll have a look into it. If the infringement occurred on a regional road, contact our nearest regional office.

Be roadwork aware - slow down and take care

You can bet you will encounter roadworks and mobile traffic management on your travels - from speed and lane restrictions and possibly a modified road layout.

There are many safety hazards to both road users and construction workers within roadwork zones. It is important to follow the rules and be courteous, even when workers are not on-site as the unsealed or uneven road surface can be dangerous.

Always follow the signs – even if workers are not on-site, avoid ‘rubbernecking’ while driving and only overtake if it is safe.

We went everyone to get home safely to their families.
