Road Closure Signs & Floodwater Warnings Vital During Wet Season

As the wet season continues across Queensland, motorists are being reminded to take road closure signs and floodwater warnings seriously, with authorities stressing that flooded roads pose significant and often hidden dangers.

During periods of heavy rainfall, the Department of Transport and Main Roads works alongside local councils to monitor road networks and ensure the safety of motorists. When flooding occurs, roads can quickly become unsafe, with water concealing washed-out sections of road, debris, and other hazards that are not visible from the driver’s seat.

According to Get Ready Queensland, driving into floodwater remains one of the leading causes of flood-related deaths across the state. While vehicles are designed to keep people safe on dry roads, they offer little protection once water is involved — regardless of the type of vehicle or a driver’s experience.

Even shallow floodwater can cause critical vehicle systems to fail. Steering can become powerless, engines and electrics can stop working, and traction can be lost in as little as 15 centimetres of water, causing vehicles to be swept away. Floodwater pressure can also prevent doors and windows from opening, making escape extremely difficult.

When water levels reach a point deemed unsafe, roads are officially closed using designated signage. These closures are put in place to protect motorists and reduce the need for emergency rescues. Motorists who ignore road closure signs can face fines of up to $233 and incur three demerit points.

Authorities urge drivers to plan ahead, check local disaster dashboards and road conditions before travelling, and never attempt to drive through floodwater. The message remains clear: If it’s flooded, forget it.

For emergency assistance, contact Police, Fire or Ambulance services by calling Triple Zero (000). For more flood safety advice and preparedness resources, visit the Get Ready Queensland website.
