Who regulates commercial vehicles in Alabama?

The ALEA Highway Patrol's Motor Carrier Safety Unit enforces federal and state motor carrier safety rules in Alabama, including roadside inspections and carrier records reviews. FMCSA remains the federal safety authority, and ALEA can inspect required carrier records during normal business hours (Ala. Code 32-9A-3).

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

Yes. Ala. Code 32-9A-2 adopts the federal motor carrier safety rules, including Part 396. Alabama-only property carriers at 26,000 lb or less are exempt from those rules, but passenger buses and vehicles hauling hazardous materials or hazardous waste don't get that exemption (ALEA intrastate regulations).

ALEA notes that any business vehicle over 10,000 lb can still be stopped and inspected at roadside, even if it runs only in Alabama.

What annual or periodic inspections does Alabama require?

The federal annual, at least every 12 months, for every covered truck, tractor, trailer and bus, with proof of inspection on the vehicle. Alabama doesn't run a general state program that replaces it. The only Alabama program on FMCSA's accepted list is the Alabama LPG Board's, which is limited to LPG vehicles.

Driver inspection and DVIRDrivers of covered CMVsBefore each trip; written report when a defect is found49 CFR 396.11 and 396.13

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

The federal annual can be done by any inspector qualified under 49 CFR 396.19, including a carrier's own mechanic or a third party. ALEA publishes inspector qualification and annual inspection record forms for this purpose (ALEA compliance forms).

That's the model Bright Inspect is designed for. Our federal annual is designed to meet FMCSA annual inspection requirements. If your vehicle hauls LPG and falls under the Alabama LPG Board program, ask us before booking so we can confirm what you need.

What records and stickers does Alabama require?

Keep the annual inspection report 14 months, with proof of inspection on the vehicle; Alabama doesn't require a state sticker. Maintenance records are kept 1 year while the vehicle is in your fleet and 6 months after it leaves. Driver vehicle inspection reports and repair certifications are kept 3 months.

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

ALEA Motor Carrier Safety Unit troopers conduct roadside inspections; Alabama generally requires officers issuing these citations to have completed the CVSA basic course. 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 clean roadside inspection doesn't replace your annual.

Alabama DOT inspection FAQs

You don't need a station. Alabama uses the federal annual model, so a qualified inspector can inspect your truck anywhere. Bright Inspect does it where your truck is parked.

Usually not under Alabama's intrastate rules, which start at 26,001 lb for property carriers. It does if it carries placarded hazmat or hazardous waste, or if it ever crosses state lines, where the federal 10,001 lb threshold applies.

No. Alabama has no state sticker for the annual. You need proof of a current federal inspection on the vehicle, which can be the report, a sticker or a decal with the required details.

Yes, for trucks, trailers and buses under the federal annual model Alabama uses. For LPG vehicles, ask us first.
