How to prepare for DOT blitz week, every week of the year
The blitz weeks get the attention, but the inspection behind them is the same one a truck can get on any day. In 2026, two of CVSA's enforcement campaigns came with no warning at all.
2026 International Roadcheck in numbers
DOT blitz week is the informal name for CVSA's enforcement campaigns: the 72-hour International Roadcheck, Operation Safe Driver Week, and Brake Safety Week. To prepare, check every truck the way an inspector would, fix defects before trucks move, keep each driver's documents and logs inspection-ready, and treat every week as a possible blitz.
The most common question about DOT blitz week is when the next one is. It is a fair question with a risky premise: in 2026, CVSA ran an unannounced Brake Safety Day and an unannounced hazmat blitz, and the Level I inspection used during Roadcheck is the most common inspection type all year.
I lead operations at Simplex, and I treat blitz readiness as a routine rather than an event. The campaign calendar tells you what inspectors will emphasize. Your preparation should not depend on it.

Key takeaways
Blitz week means CVSA's campaigns
International Roadcheck, Operation Safe Driver Week, and Brake Safety Week are CVSA initiatives carried out by inspectors in Canada, Mexico, and the U.S.
Every announced 2026 campaign is over
Roadcheck ran May 12-14, Safe Driver Week July 12-18, and Brake Safety Week August 23-29. CVSA posts 2027 dates at the end of this year.
Some blitzes come without notice
Brake Safety Day on April 14 and a five-day hazmat blitz on June 8-12, 2026, were not announced in advance.
Brakes and credentials drive out-of-service orders
At 2026 Roadcheck, 39.1% of vehicle out-of-service violations were brake-related, and a missing medical card was the top driver violation.
Readiness is a routine, not a sprint
Walk-arounds, closed-out defect reports, a current annual inspection, and a complete driver document kit cover what inspectors check.

What is DOT blitz week?
DOT blitz week is what drivers call the Commercial Vehicle Safety Alliance's (CVSA) announced enforcement campaigns, when inspectors across North America concentrate on commercial vehicles and drivers. It is not one federal event. CVSA sponsors International Roadcheck, for example, with participation from FMCSA and agencies in Canada and Mexico.
| Campaign | Format | What it targets |
|---|---|---|
| International Roadcheck | 72 hours, mostly Level I inspections | Drivers and vehicles, with one driver and one vehicle focus area each year |
| Operation Safe Driver Week | 7 days of traffic enforcement | Unsafe driving by truck and car drivers |
| Brake Safety Week | 7 days of inspections | Brake systems and components |
| Brake Safety Day | 1 day, not announced in advance | Brake systems and components |
Roadcheck inspections are mainly the North American Standard Level I Inspection, a 37-step check of the driver's operating requirements and the vehicle's mechanical fitness. Our guides to CVSA inspection types and the nine DOT inspection levels explain what each level covers.
Each campaign has its own guide: CVSA International Roadcheck, Operation Safe Driver Week, and Brake Safety Week. This one covers what they share: how to prepare.
When is the next DOT blitz week?
As of September 24, 2026, every announced CVSA campaign for 2026 has already taken place. CVSA says it will post the 2027 dates for International Roadcheck, Operation Safe Driver Week, and its brake safety campaigns at the end of this year.
| Campaign | 2026 dates and focus | Result |
|---|---|---|
| Brake Safety Day | April 14, unannounced; drums and rotors | 4,021 inspections; 14.3% of vehicles out of service for brakes |
| International Roadcheck | May 12-14; ELD tampering and cargo securement | 54,575 inspections; 19% of vehicles and 5.8% of drivers out of service |
| Hazmat blitz | June 8-12, unannounced; hazardous materials loads | 5,046 inspections in the U.S. and Canada; 13.5% of vehicles out of service |
| Operation Safe Driver Week | July 12-18; reckless, careless, or dangerous driving | Not yet published |
| Brake Safety Week | August 23-29; drums and rotors | Not yet published |
Roadcheck is the most predictable. It fell in mid-May in each of the last four years: May 16-18, 2023; May 14-16, 2024; May 13-15, 2025; and May 12-14, 2026, according to CVSA's results archive.
What do inspectors find during blitz week?
Mostly brake, tire, and driver credential problems. During 2026 International Roadcheck, inspectors placed 10,350 vehicles (19%) and 3,184 drivers (5.8%) out of service, which means they could not continue until the violation was corrected.
| Rank | Vehicle | Driver |
|---|---|---|
| 1 | Brake systems (24.3%) | No medical card (27.0%) |
| 2 | Tires (20.9%) | Hours of service (23.4%) |
| 3 | 20% defective brakes (14.9%) | No commercial driver's license (15.6%) |
| 4 | Cargo securement (12.4%) | English proficiency (9.1%) |
| 5 | Lights (11.9%) | False records of duty status (6.7%) |
Brake systems and 20% defective brakes together made up 39.1% of vehicle out-of-service violations. The year's focus areas landed mid-table: cargo securement ranked fourth, and ELD tampering drew 146 driver out-of-service orders, the seventh most cited.
Almost everything on that list is caught by routine checks. None of it depends on knowing the date of the next campaign.
How to prepare for DOT blitz week: a checklist
Each step maps to something a Level I inspector checks, and each one works in any week of the year.
Step 1: Walk every unit the way an inspector would
CVSA's vehicle inspection cheat sheet lists what inspectors examine: brakes, coupling devices, fuel and exhaust, frame, lighting, cargo securement, steering, suspension, and tires, wheels, rims, and hubs. Use it as your yard checklist. For brakes, that means listening for air leaks, measuring pushrod travel, and confirming the air system holds 90 to 100 psi.
Step 2: Fix defects before the truck moves
A driver must be satisfied that the brakes, steering, lights, tires, coupling devices, and other listed parts are in good working order before driving (49 CFR 392.7). When a driver vehicle inspection report lists a safety defect, the carrier must repair it and certify the repair before the vehicle runs again, then keep the report for three months (49 CFR 396.11). Carriers operating a single vehicle are exempt from this written-report rule, but the driver's duty under 392.7 still applies.
Step 3: Confirm the annual inspection is on board
Every vehicle in the combination, including each trailer, needs a periodic inspection within the preceding 12 months, with documentation on the vehicle (49 CFR 396.17). The inspection report or a sticker or decal with the required details both count.
Step 4: Build each driver's document kit
CVSA's driver inspection cheat sheet lists what the inspector checks:
- License or CDL: expiration date, class, endorsements, restrictions, and status
- Medical examiner's certificate, plus a skill performance evaluation certificate if one applies
- Record of duty status and supporting documents, and the ability to transfer ELD records on request
- Printed copies of any exemption the driver is using, which CVSA recommends to avoid delays
- In the U.S., a Drug and Alcohol Clearinghouse query to confirm the driver is not prohibited
Electronic copies are fine if the driver can display them without delay. Keep the ELD information packet in every cab, too: two instruction sheets and blank logs for at least 8 days (49 CFR 395.22). Drivers should also be ready to state the trip's starting point, destination, load, and most recent stops.
Step 5: Audit logs for edits and gaps
Review records of duty status weekly for hours-of-service violations and unexplained edits. Since April 1, 2026, CVSA's out-of-service criteria include a condition for ELD tampering that makes it impossible to determine what events occurred.
Step 6: Brief drivers on the behaviors being targeted
Operation Safe Driver Week looks for speeding, distracted driving, following too closely, unsafe lane changes, impaired or fatigued driving, and missing seat belts. Seat belts matter at every inspection: inspectors wrote 667 seat belt violations during 2026 Roadcheck. In a property-carrying truck, the driver and every other occupant of a belted seat must be buckled (49 CFR 392.16).
Step 7: Close out every inspection report
When a driver brings back an inspection report, the carrier has 15 days to certify that every violation was corrected, and keeps a copy for 12 months. Since July 22, 2026, the form goes back to the state only if the issuing agency asks for it (49 CFR 396.9).
