Can a driver operate a vehicle with a major defect?

1. Only if the defect does not impact safety
2. No ✓
3. Only if it is an emergency
4. Yes

Answer: B. No

No. A driver cannot operate a vehicle that has a major defect; the defect must be repaired before the vehicle is driven again.

Why this is the answer

The handbook splits inspection defects into major and minor groups. A minor defect gets recorded on the inspection report and reported to the operator. For a major defect, the rule is different: the driver is not allowed to drive the vehicle. The handbook also says major defects have to be repaired before you operate the vehicle again. So a major defect keeps the truck parked until the repair is done, not just noted on the report.

Why the other answers are wrong

• A. Only if the defect does not impact safety — The safety impact is not the test here; the handbook treats any defect listed as major as a reason the vehicle cannot be driven.
• C. Only if it is an emergency — The passages give no emergency exception for major defects, only the requirement to repair them before operating the vehicle again.
• D. Yes — This directly contradicts the handbook, which says drivers are not permitted to drive a vehicle with a major defect.

Remember it

Think of major as parked: it must be fixed before the wheels move again.
