During the 2025 CVSA International Roadcheck, enforcement officers conducted 56,178 inspections across North America — placing 10,148 vehicles (18.1%) and 3,342 drivers (5.9%) out of service. Brake defects accounted for 41.1% of all vehicle OOS violations. Tire issues added another 21.4%. Every one of these violations maps directly to a specific CVSA inspection level checkpoint. This DOT truck inspection checklist covers all six CVSA inspection levels — from the comprehensive 37-step Level I North American Standard Inspection through Level VI Enhanced Radioactive Shipment Inspection — with every item that enforcement officers evaluate during roadside stops, weigh station checks, and annual DOT inspections. The 2026 International Roadcheck is scheduled for May 12–14 with a focus on cargo securement and ELD tampering. Book a demo to prepare your fleet.

Understanding DOT Truck Inspections
What Is a DOT Inspection?
- A DOT truck inspection is a standardized safety examination conducted by CVSA-certified enforcement officers under authority of 49 CFR 396.9. Officers can enter upon and inspect any commercial motor vehicle in operation — refusing an inspection results in an immediate out-of-service order. Six inspection levels exist, from the comprehensive Level I (37-step vehicle + driver) to the specialized Level VI (radioactive shipments). Book a demo to see how Fleet Rabbit prepares your fleet for every level.
2025 Roadcheck Results
- The 2025 CVSA International Roadcheck (May 13–15) inspected 56,178 vehicles. 18.1% of vehicles and 5.9% of drivers were placed out of service. Brake violations accounted for 41.1% of vehicle OOS, tires 21.4%, and HOS violations led driver OOS at 32.4%. However, 81.6% of vehicles and 94.1% of drivers passed without any OOS violations — proving that consistent pre-trip preparation works.
CSA Score Impact
- Every inspection — clean or with violations — is reported to FMCSA and factors into your carrier's Safety Measurement System (SMS) percentile. Under the 2026 CSA overhaul, OOS violations carry a severity weight of 2 (vs. 1 for non-OOS), violations count for 12 months (down from 24), and Vehicle Maintenance is split into "Driver Observed" categories. Clean inspections actively improve your scores. Digital inspection records demonstrate compliance history.
Level I: North American Standard Inspection
The most comprehensive inspection — a 37-step procedure checking driver credentials AND vehicle mechanical condition. Over 50% of Roadcheck inspections are Level I. Vehicles passing receive a CVSA decal valid for 3 months.

2026 Roadcheck: May 12–14 — Is Your Fleet Ready?
This year's CVSA International Roadcheck focuses on cargo securement and ELD tampering/falsification. Fleet Rabbit covers every Level I–V checkpoint with guided mobile inspections, photo documentation, and defect routing — so your trucks earn CVSA decals instead of OOS orders.

Regulatory Authority
49 CFR 396.9
Authorizes CVSA-certified officers to inspect any CMV in operation. Carriers must sign and return completed inspection reports within 15 days verifying corrections. Records retained 12 months. Book a demo to automate inspection report tracking.
North American Standard
Defines all 6 inspection levels, out-of-service criteria (updated annually on April 1), and CVSA decal requirements. The 2026 OOS criteria include updates to brake and cargo securement standards. Over 1.8 million Roadcheck inspections since 1988.
Safety Measurement System
Every inspection feeds into CSA BASIC scores. The 2026 CSA overhaul splits Vehicle Maintenance into standard and "Driver Observed" categories, reduces violation counting window to 12 months, and increases OOS severity weight to 2x. Clean inspections actively lower your percentile.
DOT Truck Inspection FAQs
What is a Level I DOT inspection?
A Level I North American Standard Inspection is the most comprehensive CVSA inspection — a 37-step procedure that checks both driver credentials (license, medical card, HOS, DVIR, alcohol/drugs) and all vehicle mechanical components (brakes, tires, lights, steering, suspension, coupling, frame, exhaust, fuel system, cargo securement). Inspectors physically get under the vehicle to check brakes and suspension. Vehicles passing without critical violations receive a CVSA decal valid for 3 months.
How long does a DOT inspection take?
A Level I inspection typically takes 45–60 minutes. Level II (walk-around) takes 15–30 minutes. Level III (driver-only) takes 10–15 minutes. Level V (vehicle-only) takes 30–45 minutes. Level VI (radioactive) can take several hours due to enhanced requirements. The time depends on vehicle condition — trucks with well-maintained equipment and organized documentation move through faster.
What happens if my truck fails a DOT inspection?
If critical violations are found, the vehicle and/or driver is placed out of service (OOS). An OOS vehicle cannot move until defects are repaired — either on-site or by tow to a repair facility. An OOS driver cannot drive until the condition is resolved. All violations are reported to FMCSA and affect CSA scores. The carrier must sign and return the completed inspection report within 15 days verifying violations were corrected. Book a demo to see how Fleet Rabbit tracks violation resolution.
What is a CVSA decal and how do I get one?
A CVSA decal is placed on a CMV after a Level I, Level V, or Level VI inspection when no critical vehicle violations are found. The decal is valid for up to 3 months and signals to other inspectors that the vehicle recently passed inspection. During the 2025 Roadcheck, 16,521 CVSA decals were distributed. Having a current CVSA decal may reduce the likelihood of being selected for another full inspection.
Can I refuse a DOT inspection?
No. CVSA-certified enforcement officers are authorized under 49 CFR 396.9 to enter upon and inspect any CMV in operation. Refusing an inspection results in an immediate out-of-service order and additional penalties. Cooperate fully, present documents when asked, and remain professional. Having organized documentation and a well-maintained vehicle is the best strategy.
What is the 2026 CVSA Roadcheck focusing on?
The 2026 International Roadcheck is scheduled for May 12–14, 2026. This year's focus areas are cargo securement and ELD tampering/falsification. Inspectors will closely examine load securement methods, blocking and bracing, and will look for evidence of ELD data manipulation. Fleets should review cargo securement procedures and ensure ELD systems are functioning correctly with accurate data.
How does a clean inspection affect my CSA score?
Every inspection — clean or with violations — feeds into your carrier's SMS percentile. A clean inspection with no violations actively improves your score by adding inspection volume without adding violation weight. Under the 2026 CSA overhaul, OOS violations carry 2x severity weight, violations count for only 12 months (down from 24), and fleets with high inspection counts and low violation rates see significant percentile improvements.
What are the most common DOT inspection violations?
Based on 2025 CVSA Roadcheck data: brake system issues (41.1%) are the leading vehicle OOS cause, followed by tire violations (21.4%). For drivers, hours-of-service violations (32.4%) lead, followed by no CDL (24.4%) and no medical card (14.9%). False records of duty status accounted for 10% of driver OOS. These same violations have been the top causes for multiple consecutive years — making them the most predictable and preventable defects. Book a demo to see how Fleet Rabbit targets these exact violation categories.
Conclusion
DOT truck inspections are not random — they follow the standardized CVSA inspection levels that have been refined over 1.8 million roadside inspections since 1988. The violation patterns are remarkably consistent year over year: brakes, tires, hours of service, and driver credentials. The fleets that pass 81.6% of the time (2025 Roadcheck data) are the ones that maintain consistent pre-trip inspection programs covering every Level I checkpoint, keep documentation organized and current, and track defect resolution through a documented DVIR chain of custody. This checklist covers all six CVSA levels — giving your drivers and fleet managers the complete reference for what enforcement officers evaluate at every type of roadside encounter.
81.6% of Trucks Pass Roadcheck. Be in That Majority.
The 2025 CVSA Roadcheck proved it again: fleets with consistent pre-trip inspection programs, organized documentation, and proactive maintenance pass at 5x the rate of those without. Fleet Rabbit covers every Level I–V checkpoint with guided mobile inspections, timestamped photo evidence, brake stroke tracking, and automated DVIR chain of custody — turning DOT inspection readiness from a scramble into a daily routine.
