Loose chippingsBelgium
1. Loose chippings
Loose chippings are small stones or gravel lying on the road surface, often after roadworks or surface treatment. They can reduce tyre grip, increase braking distance and be thrown into the air by passing vehicles, potentially damaging windscreens or other vehicles. Drivers should reduce speed, increase their following distance and avoid sudden acceleration, braking or steering. Extra space should also be kept from other vehicles where loose stones may be projected from their tyres.
Is there a traffic sign for loose chippings in Belgium?
Yes. Belgium uses warning sign A17 for the projection of loose chippings. It warns drivers of a road section where stones or gravel may be thrown up by passing vehicles.
What should you do when you see the loose-chippings sign in Belgium?
Reduce speed where necessary, increase your following distance and avoid sudden manoeuvres. Drivers must adapt their speed to the road and traffic conditions, including a surface covered with loose stones.
Where can the loose-chippings warning sign be used in Belgium?
The A17 sign can be used where there is a risk of gravel or small stones being projected from the road surface, for example after certain roadworks or resurfacing treatments.
Can loose chippings damage another vehicle in Belgium?
Yes. Loose stones can be thrown up by tyres and damage windscreens, lights or bodywork. Keeping extra distance from other vehicles can reduce the risk.
Will Belgium’s new Road Code still use the loose-chippings warning sign?
Yes. The new Code of the Public Road retains A17 for the projection of loose chippings.
