You have to be at least 18 years old to drive a tow truck within a single state, and at least 21 to drive one across state lines. Those age floors come from federal commercial motor vehicle rules, but the practical starting age is usually higher because commercial auto insurers, employer policies, and CDL testing timelines push most new drivers into their early twenties before they get behind the wheel of a tow truck for pay.
21 to Cross State Lines
Federal regulations require drivers to be at least 21 to operate a commercial motor vehicle in interstate commerce.1eCFR. 49 CFR 391.11 – General Qualifications of Drivers For tow trucks, this applies to any rig classified as a CMV, including lighter trucks that don’t require a CDL but still meet the 10,001-pound gross combination weight rating threshold. If your route crosses a state border even once, you need to be 21.
The FMCSA ran a three-year Safe Driver Apprenticeship Pilot that allowed 18-to-20-year-olds to drive interstate under supervised conditions, but that program officially ended on November 7, 2025.2Federal Motor Carrier Safety Administration. Safe Driver Apprenticeship Pilot (SDAP) Program As of 2026, there is no active federal program allowing drivers under 21 to operate CMVs across state lines. Drivers who were already enrolled in the pilot and completed training received individual exemption extensions until their 21st birthday, but no new applicants are being accepted.
18 to Drive Within Your State
Federal rules allow CDL holders to be as young as 18 for driving that stays entirely within one state. All 48 contiguous states and the District of Columbia currently permit 18-, 19-, and 20-year-old drivers to obtain a commercial learner’s permit or CDL and operate intrastate.3Federal Motor Carrier Safety Administration.

An 18-year-old going the CDL route also has to complete Entry-Level Driver Training through a provider on the FMCSA’s Training Provider Registry before taking the skills test.4Federal Motor Carrier Safety Administration. Entry-Level Driver Training (ELDT) The federal rules don’t set a minimum number of classroom or driving hours, but some states add their own hour requirements on top, which affects how long you’ll be in training before you can test.
When No CDL Is Required
Not every tow truck demands a commercial driver’s license. If the tow truck alone stays under a 26,001-pound gross vehicle weight rating, the truck-plus-towed-vehicle combination stays under 26,001 pounds, and no hazardous materials are involved, no CDL is required. That covers a lot of light-duty flatbeds and wheel-lift trucks handling everyday passenger-vehicle tows.
For a non-CDL tow truck, the minimum age is simply whatever your state requires for a standard driver’s license, typically 16 to 18. In practice, though, tow companies almost never hire drivers that young. Insurance underwriting, employer liability, and the physical demands of the work mean non-CDL tow positions rarely go to anyone under 18.
One warning about the “no CDL” category: if the truck and towed vehicle together exceed 10,001 pounds GVWR, the rig is still classified as a commercial motor vehicle under federal safety regulations even without a CDL requirement.5Federal Motor Carrier Safety Administration. CMV Definition for Combination Vehicles Under 10,001 Pounds That triggers the 21-year-old age floor for interstate work, and it also brings in federal drug and alcohol testing, hours-of-service rules, and maintenance standards. Skipping the CDL doesn’t skip those obligations.
Why 21 Is Often the Real Minimum
Even where the law allows an 18-year-old to drive a tow truck intrastate, commercial auto insurance creates a separate barrier. Insurers are generally reluctant to cover drivers under 21 in commercial vehicles because there’s limited claims data for that age group. When carriers do agree to underwrite young drivers, they typically demand enhanced safety technology on the truck and detailed documentation of the company’s training program.
Larger trucking operations that self-insure have more flexibility to hire 18-year-old drivers, since they absorb the risk internally rather than persuading an external insurer. But most tow companies are small businesses that depend on commercial policies, and those policies frequently set a minimum driver age of 21 or even 23 regardless of what the CDL regulations allow. This is the single biggest gap between the legal minimum and the hiring reality, and it’s the reason a lot of applicants who are eligible on paper still get turned away at the door.
Other Qualifications a Young Driver Still Has to Clear
Age gets you in the door, but a tow truck driver has to meet several other federal requirements before starting work.
DOT Medical Card
Every CDL holder and every driver of a CMV in interstate commerce needs a valid Medical Examiner’s Certificate. You get it by passing a physical exam with a medical examiner listed on the FMCSA’s National Registry. The certificate lasts up to 24 months, though the examiner can issue a shorter one if a condition needs monitoring.6Federal Motor Carrier Safety Administration. DOT Medical Exam and Commercial Motor Vehicle Certification The standards cover vision, hearing, blood pressure, and conditions that could cause a loss of consciousness behind the wheel.7eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers
Drug and Alcohol Testing
CDL holders and all CMV drivers are subject to federal drug and alcohol testing, including pre-employment screening, random selection during the year, post-accident testing, and reasonable-suspicion testing.8eCFR. 49 CFR Part 382 – Controlled Substances and Alcohol Use and Testing A positive test or refusal results in immediate removal from safety-sensitive work and triggers a return-to-duty process with a substance abuse professional. This applies to non-CDL tow truck drivers too if the vehicle qualifies as a CMV by weight.
Clean Driving Record
A clean driving record is a practical requirement, not a preference. CDL holders are held to stricter standards than regular drivers, and serious traffic violations, DUI convictions, or at-fault accidents can lead to CDL disqualification and make you uninsurable for commercial work. Most tow companies pull motor vehicle records during hiring and periodically afterward, and many also run criminal background checks, particularly for companies with municipal contracts or law-enforcement rotation work, where local ordinances often impose their own screening requirements.
Air Brake Testing
Most medium- and heavy-duty tow trucks use full air brake systems. If you don’t pass the air brake knowledge test or don’t take your skills test in a vehicle with full air brakes, you’ll get an “L” or “Z” restriction on your CDL that keeps you out of air-brake-equipped trucks.9Federal Motor Carrier Safety Administration. Drivers – Classes of License and Commercial Learner’s Permits For tow work, that restriction shuts you out of most CDL-level rigs, so plan to test in an air-brake vehicle from the start.
