DOT regulations for hot shot trucks

DOT rules for hotshots are the same federal motor carrier rules that cover semis, with one big switch: the CDL line. Below it, you follow most of the rules without the CDL and the testing program. Above it, you follow all of them. This checklist covers both.

When the rules apply

A vehicle or combination with a GVWR or GCWR of 10,001 lb or more, used in interstate commerce, is a commercial motor vehicle under 49 CFR 390.5. Almost every hotshot rig qualifies. Intrastate carriers follow state rules, which often mirror the federal ones.

Drug and alcohol testing (CDL hotshots only)

If you or your drivers need a CDL, you're covered by the DOT drug and alcohol program: a written policy, a pre-employment test, random testing through a pool, post-accident and reasonable-suspicion testing, and Clearinghouse registration with queries. As an owner-operator with your own authority, you're both employer and driver, so most join a consortium. Non-CDL hotshots aren't covered. Details are in owner-operator drug testing requirements.

Size and weight rules

Federal rules set a 102 in width limit and axle and gross weight limits on the Interstate system: 20,000 lb on a single axle, 34,000 lb on a tandem and 80,000 lb gross. Hotshots rarely reach those, but the truck's and trailer's own ratings still cap what you can carry, and states set height and overall length limits. A load wider than 102 in or taller than your state's height limit needs a permit. Check axle and gross weights with the truck weight limit checker.

State rules on top

States enforce the federal rules and add their own: intrastate authority or numbers, different weight thresholds for intrastate carriers, registration and permit requirements, and sometimes extra license classes for heavy non-commercial vehicles. Before you run a new state, check its rules for your rig. A state-by-state overview is in hotshot CDL and DOT rules by state.

Hazmat in brief

Any load that requires placards brings a CDL with the H endorsement, regardless of weight, plus shipping papers, placards, emergency response information, hazmat registration for some materials and quantities, and higher insurance minimums. Most hotshots avoid placarded hazmat for that reason. If a broker offers one, check every requirement before you accept.

The new entrant safety audit

Every new carrier is reviewed by FMCSA within its first 12 months. The auditor looks at the same items on the checklist above: driver qualification files, hours of service records and supporting documents, vehicle inspection and maintenance records, insurance, and for CDL drivers, the drug and alcohol program and Clearinghouse queries. Some failures are automatic, such as having no testing program for a CDL driver or knowingly allowing a driver without a valid license or medical card to drive. Keep the files organized from day one and the audit is mostly paperwork.

Records to keep and for how long

• Hours of service records and supporting documents: six months.
• Driver qualification file: for as long as the driver works for you, plus three years after.
• Vehicle inspection and maintenance records: while the vehicle is in your control, plus six months after, with annual inspection reports kept for 14 months.
• Drug and alcohol testing records (CDL only): from one to five years depending on the record.

Exceptions and edge cases

• The CDL line: 26,001 lb or more combined with a trailer over 10,000 lb, counting actual weight if higher than ratings.
• Intrastate only: state rules apply; some states have different weight thresholds or exemptions.
• Hazmat: placarded loads need a CDL with H endorsement at any weight, plus hazmat registration and rules.
• Short-haul: drivers within 150 air miles who meet time limits can keep time records instead of logs.
• Private carriers hauling their own goods don't need MC authority but follow safety rules.

Common mistakes

• Thinking a pickup with a trailer isn't a commercial vehicle
• Missing the trailer's annual inspection
• No driver qualification file for yourself
• Running a CDL-weight load on a non-CDL license
• Letting insurance lapse, which can cancel your authority

Violations found most often are in hotshot truck safety violations. Major mechanical failures, a different kind of risk, are covered in hotshot truck warranty, and industry data in hotshot trucking statistics.
