  2. BYou must not use your vehicle's parking brake.
  3. CYou should only use your foot brake, not downshift.
  4. DYour vehicle's engine braking system is malfunctioning.
Show answer & explanation

Correct answer: A. You are prohibited from using engine-retarding devices, often due to noise.

'No Engine Braking' is a regulatory sign, typically found in residential or noise-sensitive areas, prohibiting the use of engine-retarding devices (often called 'Jake Brakes' for trucks) due to the loud noise they produce.

Why the other options are wrong

  • B. This sign refers to engine braking, not the parking brake.
  • C. While it implies using foot brakes, the core prohibition is against the noise from engine braking, which includes downshifting in a way that causes loud engine noise.
  • D. The sign is a regulation, not a diagnostic message for your vehicle.
