Steep Descent Sign
The steep-descent warning calls for engine braking in a lower gear rather than riding the Foot Brake, which can overheat. The downward slope distinguishes it from a steep-ascent sign. Especially important for Code C Heavy Vehicle.
Meaning
A steep downhill gradient is ahead.
Required driver response
Select a lower gear before descending and allow a longer stopping distance, especially when laden.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see it?” — required response.
- Distractor trap: reading it as an ascent, or confusing it with a heavy-vehicle sign.
