Is it obligatory to use an appropriate lower gear on every steep descent?
- No.
- Only on steep descents of at least one kilometer.
- Correct answer: Yes.
- Only when a “descent ahead” sign is placed at the beginning of the descent.
Why this is the answer
The correct answer in the official bank: Yes.
On every steep descent you must use a suitable lower gear, even if the slope is short and no warning sign is posted. A low gear provides engine braking, which keeps speed under control and prevents the brakes from overheating and losing effectiveness. The duty comes from the steepness itself, not from the length of the descent or the presence of a sign.
