How Old Do You Have to Be to Drive a Company Vehicle?

The minimum age to drive a company vehicle is generally 18 for a standard car or small truck, 21 for a commercial motor vehicle crossing state lines, and 18 for a commercial vehicle staying within one state. A narrow federal exception lets some 17-year-olds drive smaller company vehicles under tight limits, and even when the law allows a younger driver, the employer’s insurance policy often sets a higher floor of 21 or 25.

18 Is the Default for a Standard Company Car

Federal child labor law treats driving a motor vehicle on public roads as a hazardous occupation for anyone under 18. That means most teens cannot drive a company vehicle of any size, whatever their state license allows.¹

Workers 16 and under cannot drive on public roads for work at all, even with a valid license.² A 16-year-old may legally drive to work, but the moment they run an errand in a company car, federal law kicks in.

Once an employee turns 18, the child labor restrictions on driving fall away. An 18-year-old with a regular state license can drive a company sedan or small truck for work in most situations, subject to whatever the employer’s insurer requires.

The Narrow Exception for 17-Year-Olds

A 17-year-old may drive a company vehicle on public roads only when every one of the following conditions is met:¹

The vehicle does not exceed 6,000 pounds gross vehicle weight and has seat belts for all occupants.
All driving happens during daylight hours.
The teen holds a valid state license for the type of driving involved, has completed a state-approved driver education course, and has no moving violations at the time of hire.
The driving does not involve route deliveries, route sales, urgent time-sensitive deliveries such as pizza delivery, towing, or transporting passengers or goods for hire.
No more than two trips per day away from the primary workplace to deliver goods or transport passengers.
All driving stays within a 30-mile radius of the workplace.
Driving takes up no more than one-third of the workday and no more than 20 percent of the workweek.²

Miss any single requirement and the exception no longer applies. If the job calls for evening deliveries, carrying coworkers around town, or driving a full-size pickup over 6,000 pounds, a 17-year-old legally cannot do it.

Commercial Vehicles Crossing State Lines Require Age 21

When the vehicle qualifies as a commercial motor vehicle and the route crosses state lines, the driver must be at least 21 years old under 49 CFR 391.11.³ A pilot program that had temporarily allowed some 18-to-20-year-old CDL holders to drive interstate under supervision concluded in November 2025.⁴

A vehicle counts as a commercial motor vehicle under federal law if it meets any of these thresholds:⁵

Gross vehicle weight rating or gross vehicle weight of at least 10,001 pounds.
Designed or used to carry more than 8 passengers, including the driver, for compensation.
Designed or used to carry more than 15 passengers, including the driver, without compensation.
Any vehicle carrying hazardous materials in quantities that require federal placarding.

The interstate designation is not always obvious. A load that originated in another state or is destined for one can make the trip interstate even when the driver personally never leaves the state. The FMCSA looks at the “essential character of the movement” rather than the driver’s specific route.⁶ A local driver hauling cargo that shipped in from out of state could be performing interstate commerce, which triggers the age-21 requirement.

Intrastate Commercial Driving Starts at 18

When driving stays entirely within one state and the cargo is not interstate, the rules loosen. Most states allow drivers as young as 18 to obtain a commercial driver’s license and operate commercial vehicles on intrastate routes.⁶ A 19-year-old can legally drive a heavy delivery truck for a local company as long as the route never crosses state lines.

The CDL issued to drivers under 21 carries a “K” restriction, limiting the holder to intrastate driving. The restriction is removed automatically once the driver turns 21 and meets interstate qualifications. If a 19-year-old CDL holder accidentally takes a route into a neighboring state, both the driver and the carrier are violating federal law.

Insurance Often Pushes the Real Minimum to 21 or 25

Even when the law would allow a younger driver, the company’s insurance carrier often has the final say. Drivers under 25 are classified as “youthful operators” in commercial insurance, and adding them to a policy typically triggers a significant premium increase. Some commercial auto policies explicitly exclude drivers under 21 or under 25.

This is a contract between the insurer and the business, not a law, but violating it can void coverage entirely. If a 20-year-old employee causes an accident while driving a company vehicle and the policy excludes drivers under 21, the company could be on the hook for the full cost of damages with no insurance backing it up. Before assigning any younger employee to drive, checking with the insurer matters as much as checking the law.

Vehicle Type Can Change the Answer

15-Passenger Vans

These vans sit in a tricky spot. Used to carry 16 or more people (including the driver), they qualify as commercial motor vehicles. Even below that threshold, the National Highway Traffic Safety Administration recommends they be driven only by experienced, licensed drivers who operate this type of vehicle regularly, and notes that a commercial driver’s license is ideal.⁷ Churches, schools, and nonprofits often use these vans without recognizing the driver qualifications involved.

Hazardous Materials

Hauling placarded hazardous materials makes any vehicle a commercial motor vehicle regardless of size, and requires a hazardous materials endorsement on the driver’s CDL. The endorsement requires passing a written exam and clearing a Transportation Security Administration background check. Because hazmat transport is inherently FMCSA-regulated, the age-21 minimum applies for interstate routes, and most states require 18 for intrastate hazmat driving.

What Happens If an Employer Gets the Age Wrong

Letting an unqualified driver operate a company vehicle creates legal exposure well beyond a traffic citation. Two distinct doctrines come into play.

Under vicarious liability, an employer is typically responsible for damages when an employee causes an accident while performing job duties. Courts look at whether the driver was acting within the scope of employment. This liability applies regardless of whether the employer did anything negligent; the employee’s actions are attributed to the company.

Negligent entrustment is a separate, more damaging problem. It holds an employer liable for its own decision to let an unfit driver behind the wheel. If the company knew or should have known the driver was too young, unlicensed, or otherwise unqualified, the company bears direct responsibility. An employer who hands the keys to a 17-year-old for a nighttime delivery run is not only breaking child labor law; they are creating evidence a plaintiff’s attorney will use to argue the company knowingly endangered the public.

Quick Reference by Age

Under 16: Cannot drive a company vehicle under any circumstances.
17: May drive a company car or small truck under 6,000 pounds during daylight hours for occasional, incidental tasks within 30 miles of the workplace, but only if every federal child labor condition is met.¹
18 to 20: May drive non-commercial company vehicles without child labor restrictions. May obtain a CDL with a “K” restriction and drive commercial vehicles on intrastate routes only. Cannot drive commercial vehicles across state lines.³
21 and older: Eligible for interstate commercial driving with a full CDL and all endorsements, including hazardous materials.
Under 25: May face insurance-related restrictions or premium surcharges regardless of legal eligibility.

The legal minimum and the practical minimum rarely match. Before putting a younger worker behind the wheel, check three things in order: federal and state law, the company’s insurance policy, and the specific vehicle and route involved.
