Show answer & explanationAnswer & explanation
Correct answer: A. A steep downgrade ahead, which may require lower gear.
This warning sign indicates a steep downgrade ahead. Drivers should be prepared to shift to a lower gear to control their speed and prevent brake overheating, especially if driving a heavy vehicle.
Why the other options are wrong
- B. This is incorrect; an uphill grade would have a different symbol or text.
- C. This is incorrect; truck stops are indicated by blue guide signs.
- D. This is incorrect; prohibiting trucks would be a regulatory sign, not a warning sign.
