Gravel Road Sign
The gravel-road warning marks the start of an unsealed surface. Note the three-way confusion the test exploits: gravel-begins vs loose-stones vs the Slippery Road Sign (the one with the skidding car). Related to Following Distance.
Meaning
The tarred surface ends and a gravel road begins ahead.
Required driver response
Slow down; expect lighter steering, easier skidding and a longer stopping distance.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see it?” — required response.
- Distractor trap: confusing it with ‘slippery road’ (skidding car) or ‘loose stones’.
