Warning Signs
Steep Hill Sign
A truck on a downgrade warns of a steep descent ahead — shift to a lower gear before starting down.
What This Sign Means
Steep grade signs warn of long or sharp downhill sections where brakes can overheat and fade if you ride them continuously.
What You Should Do
Slow down and gear down before the descent. Use engine braking and apply brakes intermittently rather than continuously.
Knowledge Test Tip
The correct test answer is to gear down BEFORE the hill, not during it — especially relevant for Class 4 and commercial drivers.
