Vehicle Inspections & DVIRs — 49 CFR 396

DVIR — Driver Vehicle Inspection Report (49 CFR 396.11)

Post-trip DVIR: A driver must prepare a written report at the completion of each day's work on each vehicle operated. The report must cover at least the following parts:

• Service brakes (including trailer brake connections)
• Parking brake
• Steering mechanism
• Lighting devices and reflectors
• Tires
• Horn
• Windshield wipers
• Rear vision mirrors
• Coupling devices
• Wheels and rims
• Emergency equipment

The DVIR must:

• Identify the vehicle (unit number, plate number)
• Identify the driver
• Identify defects or list "no defects"
• Be signed by the driver

Pre-trip inspection (49 CFR 396.13) — Before operating a vehicle:

• Driver must be satisfied the vehicle is in safe operating condition
• Review the last DVIR (if any) and certify that defects have been repaired or that repair is not needed
• Sign the previous DVIR (acknowledging the certification)

DVIR with vs without defects

• No defects: Driver simply prepares the report listing parts inspected and marks "no defects." Most carriers no longer require physical retention of no-defect DVIRs (since the 2014 rule change — see 49 CFR 396.11(a)(1)). Carrier must retain at least one cycle for audit.
• Defects found: DVIR must be retained for 3 months from the date of preparation. Carrier must:
  1. Repair the defect(s).
  2. Have a mechanic certify the repair on the DVIR.
  3. The next driver pre-trips and certifies that defects were repaired (or that repair isn't necessary).

Periodic / Annual Inspection (49 CFR 396.17)

Each vehicle must undergo an annual inspection by a qualified inspector (mechanic or shop). The inspection covers:

• Brakes (service + parking)
• Coupling devices
• Exhaust system
• Frame
• Fuel system
• Lighting devices
• Cargo securement
• Steering mechanism
• Suspension
• Tires and wheels
• Windshield glazing and wipers
• Emergency equipment
• And more (see 49 CFR 396 Appendix G — "Minimum Periodic Inspection Standards")

The inspection report must be:

• Maintained in the vehicle (a copy) AND
• Kept at the principal place of business for 14 months from the inspection date

Substitute: A state-equivalent inspection (e.g., commercial state safety inspection from a state that has one) can substitute for the federal periodic inspection. Verify with FMCSA list.

Who can perform a periodic inspection? (49 CFR 396.19)

A qualified inspector — at minimum:

1. 1 year of training/experience as a mechanic OR
2. 1 year of training in a vocational school, college, or similar OR
3. Has performed roadside CMV inspections under MCSAP for 1+ year

Carrier maintains documentation of inspector qualification (resume, training certificate).

Roadside inspection vs DVIR vs annual inspection

Type	Performed by	Frequency	Document
Pre-trip	Driver	Each shift	None required; verbal certification
Post-trip / DVIR	Driver	End of each shift	DVIR form
Annual / Periodic	Qualified inspector	Once every 12 months	Annual inspection sticker + report
Roadside	DOT inspector	Random / triggered	DOT-1A or similar

Out-of-Service (OOS) criteria

A vehicle can be placed OOS at roadside if defects meet the CVSA OOS criteria. Examples (not exhaustive):

• Brake friction material < 1/8" thickness
• Brake stroke beyond adjustment limits
• Brake hose chafed to inner ply
• Front tire tread depth < 4/32"
• Rear tire tread depth < 2/32"
• Defective steering linkage
• Inoperative low air pressure warning device
• Cracked frame member
• Inoperative service brakes (> 20% defective)
• Cargo securement deficiencies (failed straps, missing tiedowns)

A driver placed OOS may NOT operate the vehicle. The vehicle must be repaired (or towed to repair facility) before continuing.

Driver OOS can happen too — for HOS violations, drug/alcohol, CDL issues, etc.

DVIR fraud / falsification

The penalty for a DVIR falsification is potentially:

• $1,150 per violation (carrier or driver)
• Disqualification of driver (for repeat falsification)
• CSA points to the carrier

DVIRs are a high-priority audit target because they're a primary source of vehicle-related BSI in the Vehicle Maintenance BASIC.

Brake-system "post-trip" exception

A driver who operates a CMV equipped with anti-lock brake systems (ABS) and full air brakes still must perform a post-trip inspection. The fact that a vehicle has ABS does not exempt anyone from the inspection requirement.

Quick math

A fleet of 10 power units running annual inspections at $80-150 each:

• Cost: $800-1,500/year just for paid inspectors
• Plus internal mechanic time for periodic checks

DVIRs are free (driver time only) but must be tracked + retained.

Where this fits in X3

X3's vehicles.html page tracks per-vehicle DVIR history, annual inspection due dates, and roadside inspection reports. send-compliance-notification fires vehicle_pm_overdue when a periodic inspection deadline lapses. Driver-uploaded DVIRs feed into the Vehicle Maintenance BASIC score.
