If after inspecting your vehicle, you find out that the brake lamps aren't functioning, what action should be taken?
- Ignore it until the trip is complete
- Note it on a daily report, inform the operator, and keep track of it
- Stop using the vehicle and have the defect fixed before you drive again ✓
- Drive slower than usual until you can have the defect fixed
Answer: C. Stop using the vehicle and have the defect fixed before you drive again
Stop using the vehicle and have the brake lamps fixed before you drive again.
Why this is the answer
The handbook divides defects into major and minor categories. Minor problems, such as broken clearance lights, are recorded on the inspection report and reported to the operator. Major defects must be repaired before the vehicle is operated again, and drivers are not permitted to drive with a major defect. Defective lights are also listed among reasons a commercial vehicle can be taken out of service. Since brake lamps are defective lights, the supported action is to stop using the vehicle and repair them first.
Why the other answers are wrong
- A. Ignore it until the trip is complete — Ignoring the problem until the trip ends conflicts with the rule that defective lights can take a vehicle out of service and that major defects must be repaired before further driving.
- B. Note it on a daily report, inform the operator, and keep track of it — Recording and reporting the defect is the process for minor defects such as broken clearance lights, not for a defective brake lamp that leaves the vehicle out of service.
- D. Drive slower than usual until you can have the defect fixed — Driving slower does not replace repairing a major defect or a defective light; the handbook says the vehicle must not be operated until the problem is fixed.
Remember it
If the lamp that tells other drivers you are braking is out, the truck stays parked until it is fixed.
