1.Walk me through your pre-trip inspection.
Why they ask
It's the fastest way to tell a careful driver from someone who signs the DVIR without looking. They've heard every shortcut.
How to answer
- Go in order: engine compartment, cab and gauges, lights, then a full walkaround of tractor and trailer
- Name specific checks: air brake leak-down, slack adjusters, tire tread and inflation, fifth wheel locking jaws, glad hands and air lines
- Say what you do when you find something, like writing it up on the DVIR and calling the shop before you roll
- Mention you do a post-trip too, so problems get fixed overnight instead of at the next morning's dispatch
