When is a pre-trip inspection required?

  1. If there is visible damage
  2. Weekly
  3. Daily ✓
  4. If a warning light comes on the dashboard

Answer: C. Daily

A pre-trip inspection is required daily.

Why this is the answer

The handbook says the National Safety Code applies to most commercial vehicles and requires the vehicle you will drive to be inspected daily. It also says you are responsible for making sure your vehicle is safe every time you drive, and the pre-trip inspection is designed to help you do that. So the timing is daily, not something that waits for visible damage or a dashboard warning.

Why the other answers are wrong

Remember it

Treat the pre-trip inspection as a daily habit that comes before you drive, not as a response to a problem.
