Flood barriers and signs

Queensland experiences hot summers with heavy rainfall. This can cause flooding and roads can be cut off or washed away.

If you drive in an area that has been affected by flooding, signs will warn you of the roads that are unsafe to use. Even if the floodwater has subsided, the road may not to be safe to use.

If you ignore these signs, you may be fined.

Plan ahead

Don’t let road closures delay you.

Check for closed roads or changed road conditions online or by calling 13 19 40.

Never drive through floodwater

More than half of flood-related deaths are a result of driving through floodwater. Even if it looks calm, no one can predict what floodwater will do or what’s happened to the road underneath. Any amount of swift flowing water can sweep away your car, no matter what you drive. Don’t risk it.

If it’s flooded, forget it. Always have a Plan B.
