DOT compliance
Plain-language DOT rules for vocational fleets and drivers, plus the TMS, telematics and ELD tools that keep records straight.
DOT Compliance Center
Most vocational trucks fall under federal motor carrier rules, even when the work is local. Short-haul exceptions cut paperwork, but they don't remove registration, driver files, drug testing, inspections or load containment.
A USDOT number for each carrier, with the MCS-150 updated every two years.
Vocational note: FMCSA is moving registration to a new online system during 2026.
Class A or B CDL for trucks over 26,000 lb, and entry-level driver training for new CDL holders.
Vocational note: Tank (N) endorsement for water and vacuum tankers; most fuel haulers need tank plus hazmat (X).
A DOT medical card, valid up to 24 months, and enough English to read signs and talk to officers.
Vocational note: English proficiency has been an out-of-service violation since 2025.
A testing program, plus Clearinghouse queries at hire and at least once a year.
Vocational note: Drivers in prohibited status lose CDL driving privileges until they return to duty.
11 hours driving in a 14-hour window. ELDs for drivers who must keep logs.
Vocational note: Short-haul exception: within 150 air miles, released in 14 hours, time records instead of logs.
Pre-trip checks, driver vehicle inspection reports and an annual inspection on every truck.
Vocational note: Electronic DVIRs are allowed; inspect bodies, PTOs and booms too.
Bridge Formula and axle limits, plus state oversize and overweight permits.
Vocational note: Frost laws hit dump, logging and heavy-haul trucks hardest.
Cargo must not leak, spill, blow or fall from the truck (49 CFR 393.100(b)).
Vocational note: A top roadside violation for dump and refuse trucks. See below.
Material containment · Dump & refuse trucks
Dirt, gravel and asphalt blowing from a dump body, or trash and liquid escaping a refuse truck, break federal law (49 CFR 393.100(b)), damage windshields and cause crashes. Road debris was involved in more than 200,000 crashes from 2011 to 2014, with about 39,000 injuries and about 500 deaths (AAA Foundation, 2016).
A violation counts in the Vehicle Maintenance BASIC for 24 months: 3x for the first 6 months, 2x to 12 months, then 1x, plus 2 points if placed out of service. FMCSA is revising CSA scoring, including a simpler 1–2 severity scale, so check the current method. Sources: 49 CFR 393.100, 49 CFR 386 App. B, J. J. Keller, AAA, AAA.
General information, not legal advice. Rules, penalty amounts and scoring change, and states add their own requirements. Confirm with FMCSA (fmcsa.dot.gov) and your state. Reviewed October 2026.
Fleet tech guides
Freight software was built for lanes and trailers. Vocational fleets bill by the load, yard, stop or call, and the truck does its real work standing still. Here is how the two systems fit the jobs.

FAQ
Short answers on the federal rules vocational fleets ask about most. General information, not legal advice.
Usually, yes. Most vocational trucks fall under federal motor carrier safety rules, or state rules based on them, even when the work is local. Short-haul exceptions cut paperwork, but registration, driver files, drug and alcohol testing, inspections and load containment still apply.
Drivers who stay within 150 air miles of their work reporting location and are released within 14 hours can keep time records instead of logs or an ELD. Hours-of-service driving limits still apply.
Only drivers who must keep logs. Drivers using the short-haul exception keep time records instead, and drivers who need logs 8 days or fewer in any 30-day period, or who drive trucks with engines older than model year 2000, can use paper logs.
Every two years, with the MCS-150 biennial update, even if nothing has changed. FMCSA is moving registration to a new online system during 2026, so check the current process.
Up to 24 months. A medical examiner can certify a driver for a shorter period when a health condition needs closer monitoring.
A federal database of CDL drug and alcohol violations. Employers must query it before hiring a CDL driver and at least once a year for every CDL driver. Drivers in prohibited status lose CDL driving privileges until they complete the return-to-duty process.
Federal penalties reach $19,246 per violation for a motor carrier and $4,812 for a driver. States add fines from $10 to $5,000, at least 16 allow jail time, and the violation counts against the carrier's CSA safety score.
