Practice question

What is the proper technique for descending a long, steep grade in a fully loaded Category C truck?

  1. Select the appropriate low gear before starting the descent, activate the auxiliary retarder/exhaust brake, and use snub braking (short, firm brake applications) only when necessary to control speed
  2. Shift into neutral to save fuel and maintain continuous light pressure on the footbrake
  3. Descend in top gear at 90 km/h and pull the parking brake whenever speed exceeds 100 km/h
  4. Turn off the engine ignition key to maximize engine vacuum

Answer: A — Select the appropriate low gear before starting the descent, activate the auxiliary retarder/exhaust brake, and use snub braking (short, firm brake applications) only when necessary to control speed
