DOT inspection requirements in Delaware

The Delaware State Police enforce truck and bus safety. Delaware adopts federal rules, covering intrastate property vehicles at 26,001 lb, plus vehicles seating 16 or more and placarded hazmat. Delaware has no separate state program for commercial vehicles, so a qualified inspector's federal annual is the standard. School buses get DMV inspections twice yearly.

Who regulates commercial vehicles in Delaware?

The Delaware State Police enforce motor carrier safety, with CVSA-certified officers running roadside inspections. Delaware's motor carrier safety law is in Title 21, Chapter 47 of the Delaware Code, and the Department of Education regulates school bus specifications and school transportation.

Does Delaware follow federal rules, and what are the intrastate thresholds?

Yes. Delaware adopts the federal motor carrier safety rules through 21 Del. C. 4702 and its administrative code. Delaware-only property vehicles are covered at 26,001 lb or more. Vehicles with seating for 16 or more and placarded hazmat at any weight are also covered. Intrastate farm vehicles are exempt from the Part 396 recordkeeping rules (21 Del. C. 4708).

What annual or periodic inspections does Delaware require?

The federal annual, at least every 12 months, for every covered CMV, with each unit of a combination inspected on its own. Delaware doesn't run a separate state annual program or issue a Delaware annual sticker for commercial vehicles.

Who can perform the inspection, and is a technology-based inspection accepted?

The federal annual can be done by an inspector qualified under 49 CFR 396.19; a carrier can inspect its own vehicles if its inspector is qualified. That's the model Bright Inspect is designed for, and our federal annual is designed to meet FMCSA annual inspection requirements.

School buses get a DMV inspection twice a year, and our federal annual is not a substitute for it. We confirm what your vehicle needs before you pay.

What records and stickers does Delaware require?

Keep the annual inspection report 14 months, or until a newer one replaces it, with proof of inspection on the vehicle. A sticker is optional: the proof can be the full report, a sticker, a decal or another document with the required details. Maintenance records follow federal retention rules.

What happens if your inspection is expired at a roadside stop in Delaware?

CVSA-certified Delaware State Police officers inspect vehicles during traffic stops, at weigh stations and in targeted enforcement. Federal rules let an officer cite you under 49 CFR 396.17(c) when proof of a current annual inspection isn't on the vehicle; it carries a CSA severity weight of 4. The officer gives the driver an inspection report. The carrier must certify that listed violations were corrected and return it within 15 days, and keep a copy for 12 months (49 CFR 396.9). Fines are set by state law. A CVSA decal from a passed roadside inspection doesn't replace your annual.
