DVIR Best Practices: Getting Pre- and Post-Trips Right

The Driver Vehicle Inspection Report is supposed to be the frontline defense against mechanical failures and roadside violations. In practice? We've seen too many carriers where DVIRs are a checkmark exercise — "all good" scribbled on a form without anyone actually walking around the truck.

That approach works until it doesn't. And when it doesn't, it usually involves a tow truck and a very expensive OOS violation.

What the Regulation Requires

Under §396.11, at the end of each driving day, the driver must prepare a written report covering at minimum:

• Service brakes, parking brake
• Steering mechanism
• Lighting devices and reflectors
• Tires, horn, windshield wipers
• Rear vision mirrors
• Coupling devices (tractor-trailers)
• Wheels and rims
• Emergency equipment (fire extinguisher, reflective triangles)

If defects are found, the carrier must repair them and certify the repairs in writing before dispatching the vehicle. DVIRs must be retained for 3 months.

Pre-Trip vs Post-Trip

The federal requirement is technically a post-trip DVIR. But most carriers require a pre-trip inspection too — and for good reason. A pre-trip catches issues before the truck hits the road, not after. Some states also mandate pre-trip inspections.

Smart carriers do both. The pre-trip is your last chance to catch a problem before it becomes a roadside violation.

What a Good DVIR Process Looks Like

1. Use a structured checklist — not a blank form. List every component so the driver can't skip anything.
2. Require photos for defects — if you're using a digital DVIR tool, defect photos create accountability and help mechanics prepare for repairs.
3. Time the inspection — a thorough walk-around takes 10-15 minutes for a tractor-trailer. If a driver submits a DVIR in 30 seconds, they didn't inspect anything.
4. Review defects same-day — Don't let defect reports pile up. If a driver reports a brake issue, ground the truck until it's fixed.
5. Sign the repair certification — After fixing a defect, a mechanic or carrier rep must sign off. This goes with the DVIR.

Digital vs Paper DVIRs

Paper works. It's legal. But digital DVIRs are better in every way — timestamped, geotagged, searchable, and impossible to lose in a truck cab. Most ELD providers include a DVIR module. If yours doesn't, find one that does.

The real benefit of digital: compliance visibility. You can see who completed their DVIR, who skipped it, and what defects are outstanding — all from your desk.
