Show answer & explanationAnswer & explanation
Correct answer: D. The use of engine braking (compression release engine brakes) is prohibited.
A 'NO ENGINE BRAKING' sign is a regulatory sign, often found in residential or noise-sensitive areas, prohibiting the use of compression release engine brakes (sometimes called 'Jake Brakes') which can create loud noises. It does not prohibit regular vehicle braking.
Why the other options are wrong
- A. This is a misinterpretation; the sign refers to a specific type of braking, not engine condition.
- B. This sign prohibits, rather than mandates, engine braking.
- C. While engine braking is used on downgrades, this sign indicates it is prohibited here.
