How to Prepare Your Fleet for DOT Blitz Week
Every spring, the Commercial Vehicle Safety Alliance (CVSA) conducts International Roadcheck — the largest targeted inspection program for commercial motor vehicles in the world. Known in the industry as DOT Blitz Week or DOT Week, this 72-hour event involves inspectors across the United States, Canada, and Mexico conducting an average of 15 vehicle inspections per minute. In 2025, over 56,000 inspections were conducted, with 28.4% resulting in vehicle out-of-service violations. In 2026, DOT Blitz Week runs from Tuesday, May 12th through Thursday, May 14th, with ELD tampering, falsification, and manipulation as the primary driver focus areas.
For carriers, a DOT Blitz inspection violation isn’t just a fine — it’s a CSA score hit, potential out-of-service order, and service disruption that affects your shippers. For shippers, it’s a capacity crunch, rate spike, and potential delivery delay. Preparation is the only way to minimize impact. For a broader look at compliance requirements and freight communication during inspection season, read our guide on DOT Blitz and EDI 990 Compliance.
What DOT Inspectors Check
During International Roadcheck, inspectors conduct Level I inspections — the most comprehensive type, a 37-step process that examines both the driver and the vehicle.
Driver Documentation and Compliance
The 2026 focus areas include ELD tampering — disconnected devices, unlogged driving time, and improper edits to driver logs. Inspectors will also check for ghost drivers (claiming a co-driver when none is present), misuse of the personal conveyance exception, and improper use of other HOS exceptions. Drug and Alcohol Clearinghouse status will be verified. Driver credentials — CDL validity, medical certificate currency, and required endorsements — are checked on every inspection.
Vehicle Mechanical Condition
Vehicle inspections cover brakes (the leading cause of vehicle out-of-service violations), tires, lights and electrical systems, steering and suspension components, exhaust systems, and load securement. Any defect that constitutes an imminent hazard results in immediate out-of-service status for the vehicle.
Documentation
Carriers must have current registration, proof of insurance, operating authority documentation, and hazardous materials documentation if applicable. Missing or expired documentation contributes to violations even when the vehicle and driver are otherwise compliant.
Carrier Preparation Checklist
30 Days Before DOT Blitz Week
Schedule preventive maintenance for all vehicles that will be operating during the inspection window. Focus specifically on brakes, tires, lights, and load securement equipment — the categories that generate the most out-of-service violations. Address any deferred maintenance before the inspection window. Review CSA scores for all trucks and drivers and prioritize pre-inspection attention on units with elevated scores.
One Week Before
Review all driver qualification files for CDL expiration, medical certificate currency, and drug and alcohol program compliance. Verify ELD devices are functioning correctly and that drivers understand proper use — ELD tampering violations are easily preventable with proper training and functioning equipment. Review HOS logs for the preceding 30 days and address any patterns that indicate compliance risk.
During DOT Blitz Week
Brief all drivers before departure each day on the inspection focus areas and what to expect if stopped. Ensure drivers have all required documentation in the cab. Remind drivers that inspectors are doing their job and that a calm, professional interaction goes better than an adversarial one. If a violation is noted, document it accurately for CSA record correction processes if warranted.
Shipper Preparation
Tender Critical Freight Early
Freight that absolutely must move during DOT Blitz Week should be tendered to your contracted carrier network well in advance — the week of the event is too late to secure reliable capacity at reasonable rates. Many carriers begin accepting loads for Blitz Week dates a week or more in advance. Proper load tender communication is critical during high-volume periods. See our EDI 990 Load Tender Response Guide for best practices.
Expect Spot Rate Increases
Spot rates typically spike 10–20% during DOT Blitz Week as available capacity tightens. Learn more about how inspections impact market conditions in our article on How DOT Blitz Week Affects Freight Rates and Capacity. Many drivers voluntarily park their trucks during the 72-hour window to avoid inspection risk — even if their equipment and records are fully compliant. Build this rate volatility into your freight budget planning for May.
Lean on Pre-Vetted Carrier Networks
During tight capacity windows, the quality of your carrier network matters most. Ready2Execute’s compliance-focused carrier network means the carriers we work with are prepared for inspections year-round — they’re not the ones voluntarily parking during Blitz Week because they’re not confident in their compliance status.
Post-Blitz Week
The Friday after DOT Blitz Week typically sees a surge in freight volume as drivers re-enter the market and loads that didn’t move during the inspection window need coverage. Spot rates may remain elevated briefly before normalizing. Plan for potential Friday congestion on receiving docks if multiple delayed shipments arrive simultaneously.
