Warning Signs
Steep Hill Sign
A truck on a downgrade warns of a steep descent ahead — shift to a lower gear before starting down.
Qué significa esta señal
Steep grade signs warn of long or sharp downhill sections where brakes can overheat and fade if you ride them continuously.
Qué debes hacer
Slow down and gear down before the descent. Use engine braking and apply brakes intermittently rather than continuously.
Consejo para el examen de conocimientos
The correct test answer is to gear down BEFORE the hill, not during it — especially relevant for Class 4 and commercial drivers.
