How Old Do You Have to Be to Work at a Car Wash?

Under federal law, you have to be at least 14 years old to work at a car wash, and even then your tasks and hours are limited until you turn 16, with more restrictions dropping off at 18. The Fair Labor Standards Act sets the floor; some states raise it, so the exact rules depend on where the car wash operates.¹

What Each Age Unlocks

Federal child labor rules move in three steps at a car wash job.

At 14 and 15, you can work in retail and service settings like a car wash, but you can’t touch power-driven equipment and your hours are capped.²

At 16 and 17, the federal hour limits disappear. You can work any schedule, but you still cannot perform tasks the Department of Labor has classified as hazardous.¹

At 18, all federal child labor restrictions come off. You can operate any equipment and work any hours the employer allows.²

Hour Limits at 14 and 15

If you’re 14 or 15, federal law controls both how many hours you can work and what times of day you can be on the clock. The rules loosen when school is out.

During the school year:

3 hours maximum on a school day
18 hours maximum in a school week
Only between 7 a.m. and 7 p.m.

From June 1 through Labor Day:

8 hours maximum on a non-school day
40 hours maximum in a non-school week
Between 7 a.m. and 9 p.m.

These caps cover all your jobs combined. Working a second job doesn’t reset the counter.²

What You Can Actually Do at 14 or 15

The dividing line for this age group is power-driven machinery. Federal rules ban 14- and 15-year-olds from operating or tending any machine that runs on electricity or fuel, with narrow exceptions for standard office equipment and vacuum cleaners.³ At a car wash, that rules out the automated tunnel, pressure washers, mechanical buffers, and powered conveyors.

What’s left is still plenty:

Hand-drying vehicles with towels after the wash
Vacuuming interiors and floor mats (vacuums are specifically allowed)³
Cleaning windows with handheld spray bottles
Working the register, greeting customers, and explaining wash packages
Picking up trash and tidying the waiting area

Tasks That Stay Off-Limits Until 18

Even after you turn 16 and your hour restrictions end, some car wash tasks remain off-limits until 18. The Department of Labor has 17 Hazardous Occupation Orders that apply to all workers under 18. Two matter at car washes:⁴

Operating, servicing, or repairing power-driven hoisting equipment. Full-service car washes with vehicle lifts or hydraulic platforms fall into this category.
Driving on public roads, with one narrow exception for 17-year-olds covered below.⁵

Moving Customer Cars

Driving is where the rules trip people up, because car wash crews often need to pull vehicles forward or park them after service. If any of that driving touches a public road, the age floor is 18, with a narrow exception at 17.

A 17-year-old can drive on public roads for work only if every one of these is true:⁵

The vehicle weighs 6,000 pounds or less and has seat belts
Driving happens during daylight only
The worker has a valid state license and no moving violations
The worker has completed a state-approved driver education course
Driving is occasional — no more than one-third of any workday or 20 percent of the workweek
All driving stays within 30 miles of the workplace

Miss any one condition and a 17-year-old can’t legally drive for the job. Workers 14 through 16 can’t drive for work at all.

If cars are only being moved on a private lot and never touch a public road, the driving order may not apply. But the broader ban on power-driven machinery still keeps 14- and 15-year-olds out of the driver’s seat.

Pay for Younger Workers

The federal minimum wage is $7.25 per hour. Employers can pay a “youth minimum wage” of $4.25 per hour to any worker under 20, but only during their first 90 consecutive calendar days on the job. After 90 days, or when the worker turns 20, whichever comes first, the pay has to rise to at least the full federal minimum.⁶ An employer also cannot use the youth rate to push out an existing adult worker.

Many states set a higher minimum wage, and some don’t allow the youth subminimum at all. Where the state rate is higher, the state rate wins.

Work Permits

Many states require minors to get a work permit — sometimes called an employment or youth employment certificate — before starting a job. The application usually asks for proof of age, confirmation of school enrollment, and a description of the proposed duties from the employer. Some states issue permits through school guidance offices; others handle them at a labor department office. A handful of states don’t require permits at all. Check your state’s labor agency for the specific process.

When State Law Sets a Higher Age

Federal law is a floor. If your state’s child labor law is stricter, the state rule applies.⁷ Some states set the minimum age at 16 for commercial jobs, which would keep 14- and 15-year-olds out of car wash work entirely. Others cut back the allowed hours or require longer breaks. Before you apply, look up the rules in the state where the car wash operates.

If Your Parent Owns the Car Wash

A parent who is the sole owner of the car wash can employ their own children at any age. The Hazardous Occupation Orders still apply to workers under 18, so the same tasks stay off-limits, but the general age minimums don’t. This exemption only works when the parent is the sole owner — not a manager, partner, or franchisee at a corporate chain.⁸²
