Warning Signs
Loose Gravel Sign
Loose stones on the road can reduce tire grip and may be thrown up by passing vehicles.
What to Do
Ease off speed and avoid abrupt braking or steering on the loose surface.
A Detail to Remember
The spray of stones around the car distinguishes this image from the curved skid marks on the slippery-road sign.
Understanding Warning Signs
Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
