How to recognise the unpaved surface sign
A triangle showing a tarred road changing to a gravel surface.
Where you will see it
On a tarred road before the surface becomes gravel, particularly around farms.
What to do when you see it, step by step
- Slow down before the change.
- Watch for ditches or potholes where the surfaces meet, and expect lighter steering and longer stopping distances on gravel.
The common mistake
Slowing late and braking hard on the joint is how drivers skid.
