Ensure your straight block truck is FMCSA-compliant with this detailed DVIR inspection checklist for lights, brakes, cargo, and lift gate.

DVIR Inspection Procedures

Follow these step-by-step procedures to complete a comprehensive Driver Vehicle Inspection Report for your straight block truck. These procedures align with DOT and FMCSA requirements.

Air Brake Check Procedure

  • Build air pressure to governor cutout (about 120-140 psi)
  • Turn off engine, release parking brake, apply foot brake
  • Monitor air gauge for 1 minute (should not drop more than 3 psi)
  • Apply foot brake multiple times to reduce air pressure
  • Verify low air warning devices activate at approximately 60 psi
  • Continue reducing air pressure; parking brake should apply automatically between 20-40 psi

Light Inspection Technique

  • Turn on all lights before beginning inspection
  • Check headlights, turn signals, 4-way flashers from front
  • Activate brake lights with a brick/wood block on pedal
  • Walk around the vehicle to verify all lights functioning
  • Check reflectors and reflective tape visibility
  • Have someone assist if possible for brake light verification

Lift Gate Safety Check

  • Ensure truck is parked on level ground with parking brake set
  • Inspect hydraulic lines for leaks before operation
  • Test operation through complete cycle (up, down, tilt)
  • Check platform for stability at different positions
  • Verify safety features: toe guards, rails, warning lights
  • Return to stowed position and verify secure latching

Cargo Securement Check

  • Verify cargo weight is within truck's GVWR limits
  • Check weight distribution (not overloading axles)
  • Ensure proper tie-downs/securement devices used
  • Verify cargo cannot shift, tip, or fall during transit
