Pre-Trip Inspection
A pre-trip inspection is a mandatory walk-around inspection a commercial driver must complete before operating a vehicle. FMCSA requires drivers to inspect key components including brakes, lights, tires, steering, and mirrors and to certify the vehicle is in safe operating condition.
In Depth
Pre-trip inspections are required by FMCSA regulations (49 CFR 392.7) and typically take 30–45 minutes for a thorough inspection. Drivers must check engine compartment, cab/controls, frame, fuel/exhaust system, suspension, tires and wheels, brakes (including air pressure test), lights, and coupling devices.
Documenting pre-trip inspections protects the driver legally. If a component fails during a trip that was not noted during pre-trip, the driver can face liability. DVIRs (Driver Vehicle Inspection Reports) create a paper trail showing the vehicle's condition at the start of each shift.
Defects found during pre-trip must be reported to the carrier. The carrier must certify repairs were made before the vehicle can be put back in service. Carrying a vehicle with known defects is a serious violation that can result in out-of-service orders.
Usage Example
Example: 'During my pre-trip, I found a cracked brake chamber. I tagged the truck out of service and had it repaired before pulling the load.'

Post-Trip Inspection
A post-trip inspection is a mandatory inspection completed at the end of each driving shift where the driver checks the vehicle for any defects or damage that occurred during the trip and documents findings on a Driver Vehicle Inspection Report (DVIR).
DVIR (Driver Vehicle Inspection Report)
A DVIR (Driver Vehicle Inspection Report) is a mandatory federal form that commercial drivers must complete after each driving day to document the condition of their vehicle, noting any defects found during pre-trip or post-trip inspections.
CSA Score
A CSA (Compliance, Safety, Accountability) score is an FMCSA safety measurement system that grades carriers and drivers across seven categories called BASICs based on roadside inspection data, violation history, and crash reports. Higher scores indicate more safety risk.
ELD (Electronic Logging Device)
An Electronic Logging Device (ELD) is a device connected to a commercial vehicle's engine that automatically records driving time and Hours of Service data, replacing paper logbooks. ELDs became mandatory for most interstate commercial carriers in December 2017.
Frequently Asked Questions
How long does a pre-trip inspection take?
A thorough pre-trip takes 30–45 minutes. Rushing a pre-trip increases safety risk and your CSA score exposure if a defect is later cited at a weigh station.
What happens if I skip the pre-trip inspection?
Failure to conduct a pre-trip is a violation that can result in fines and CSA points. More importantly, it increases the risk of a breakdown or accident.
