While on duty, under which circumstances can a police officer or appointed ministry officer conduct a safety inspection on your vehicle?

  1. At any given place and time ✓
  2. Only during daylight
  3. Solely on public roadways
  4. Only within designated inspection stations

Answer: A. At any given place and time

A police officer or appointed ministry officer can conduct a safety inspection at any given place and time while you are on duty.

Why this is the answer

The truck handbook states that, besides permanent truck-inspection stations, mobile-inspection units can be set up for varying lengths of time at any location. It adds that any police officer or appointed ministry officer has authority to perform a safety inspection at any time and any location. The officer may also require you to drive to the nearest inspection station, and you must assist if requested. That directly supports the broad any-place, any-time answer rather than limiting inspections to daylight, public roads, or designated stations.

Why the other answers are wrong

Remember it

Think anywhere, anytime when an officer signals you: a commercial truck safety check is not tied to one station or one time of day.
