86. Gravel road

A gravel road is an unpaved road surfaced with gravel, crushed stone or similar loose aggregate instead of asphalt or concrete. Gravel roads are commonly found in rural areas, forests, construction zones and locations where a paved surface is unnecessary or impractical.

Drivers on gravel roads should reduce speed when necessary, increase following distance and avoid sudden braking or steering. Loose stones, dust, potholes and reduced tyre grip can make vehicle control more difficult.

What is a gravel road?

A gravel road is an unpaved road covered with gravel, crushed stone or another loose aggregate surface.

Why can gravel roads be more difficult to drive on?

Loose material can reduce tyre grip, increase stopping distance and cause stones or dust to be thrown into the air. Potholes and uneven surfaces may also be present.

How should you drive on a gravel road?

Use a suitable speed, maintain extra distance from other vehicles and accelerate, brake and steer smoothly to reduce the risk of losing traction.
