A driver discovers a defect during a pre-trip inspection that renders the vehicle unsafe to operate. What is the correct action?
Answer: Complete the DVIR, tag the vehicle out of service, and notify maintenance
When an unsafe defect is found, the driver must document it on the Driver Vehicle Inspection Report (DVIR) and place the vehicle out of service until repairs are made.
What is the minimum brake lining thickness that triggers an out-of-service condition for a front steering axle air brake on a commercial vehicle?
Answer: 1/8 inch
FMCSA out-of-service criteria specify that brake lining thickness less than 1/4 inch on front steering axles triggers an out-of-service condition, but the threshold triggering OOS for most axles is 1/8 inch (4mm).
Which document must a motor carrier retain to demonstrate that a periodic inspection was completed on each vehicle?
Answer: Annual inspection report or equivalent documentation
Motor carriers must keep a copy of the annual inspection report or equivalent documentation for 14 months to demonstrate compliance with periodic inspection requirements.

Answer: Tread depth of 2/32 inch on a front steer tire
FMCSA requires a minimum of 4/32 inch tread depth on front steer tires; 2/32 inch falls below this threshold and requires the vehicle to be placed out of service.
How long must a motor carrier retain Driver Vehicle Inspection Reports (DVIRs) that contain no defects?
Answer: 90 days
Under 49 CFR 396.11, motor carriers must retain DVIRs for at least 3 months (90 days), regardless of whether defects were noted.
