A 16-year-old in Missouri can legally work as late as they want. There is no state curfew, no nightly cutoff, and no cap on daily or weekly hours for workers who have reached their 16th birthday. The question of how late a 16-year-old can work in Missouri has no legal answer because the law simply stops regulating shift timing at that age. The real limits come from school attendance rules, a short list of federal hazardous jobs that remain off-limits until 18, and whatever your employer and family decide makes sense.
No State Curfew or Hour Cap at 16
Missouri’s child labor hour rules under RSMo 294.030 apply only to workers under 16. Those younger employees cannot work before 7:00 a.m., cannot work past 7:00 p.m. during the school year (9:00 p.m. from June 1 through Labor Day), cannot work more than three hours on a school day, and cannot work more than 40 hours in a workweek.1Missouri Revisor of Statutes. Missouri Code 294.030 – Hours of Work for Minors The Missouri Department of Labor confirms every one of those limits targets “Youth 14 and 15-years old” specifically.2Missouri Department of Labor and Industrial Relations. Youth Employment for Employers
Once you turn 16, those provisions no longer apply. Missouri’s child labor law as a whole governs youth under 16, so the state imposes no start time, no stop time, no daily hour cap, and no weekly hour cap on 16-year-old workers.3Missouri Department of Labor and Industrial Relations. Youth Employment A midnight close, an overnight stocking shift, a double on a Saturday — all legal under state law.
Federal Law Agrees
The Fair Labor Standards Act takes the same position. Federal regulations under 29 CFR Part 570, Subpart C set detailed hour and time-of-day restrictions for 14- and 15-year-olds, and those restrictions expire at 16.4eCFR. 29 CFR Part 570 – Child Labor Regulations, Orders and Statements of Interpretation The U.S. Department of Labor states that the federal youth employment provisions “do not restrict the number of hours or times of day that workers 16 years of age and older may be employed,” and that 16- and 17-year-olds “may be employed for unlimited hours in any occupation other than those declared hazardous.”5U.S. Department of Labor. Fact Sheet 43 – Child Labor Provisions of the FLSA for Nonagricultural Occupations
Because Missouri and federal rules line up, there is genuinely no legal ceiling on when or how long a 16-year-old can work in the state.
School Attendance Still Runs Through Age 17
This is where many families get caught off guard. Missouri’s compulsory attendance age is not 16. RSMo 167.031 requires children to attend school regularly through age 17 or until they have completed 16 credits toward high school graduation, whichever comes first.6Missouri Revisor of Statutes. Missouri Code 167.031 – School Attendance Compulsory No labor law restricts your shift end time, but you still cannot skip school to pick up more hours.
An employer who schedules a 16-year-old during required school hours is not violating a child labor statute, but the absence can trigger truancy consequences for the student and the parents. The practical effect is that weekday availability during the school year is limited to before and after school, plus weekends and school holidays. A late shift that ends at midnight is legal; one that overlaps with first period is a school problem, not a labor one.
Missouri does offer a formal workaround. A school superintendent or a court can excuse a student between 14 and 17 from attending school full time when the student has obtained legal employment.7Missouri Department of Elementary and Secondary Education. Compulsory Attendance Law That requires approval through official channels, not an informal arrangement with an employer.
Jobs and Tasks Still Off-Limits at 16
The fact that a 16-year-old can work at any hour does not mean every job is open. Federal Hazardous Occupations Orders prohibit anyone under 18 from performing certain categories of dangerous work, regardless of what state law allows. Among the prohibited tasks:8U.S. Department of Labor. What Jobs Are Off-Limits for Kids
- Power-driven woodworking machinery, including chain saws, nailing machines, and sanders
- Power-driven metal forming, punching, and shearing machines
- Power-driven meat slicers, saws, and choppers, including in restaurant and deli settings
- All work on or about a roof, including ground-level tasks
- Underground mining, open-pit mines, quarries, and wrecking operations
- Forklifts, skid-steer loaders, backhoes, boom trucks, and scissor lifts
- Power-driven bakery machines such as dough mixers, rollers, and sheeters
- Explosives manufacturing or storage
- Logging and sawmill operations
- Balers and compactors, including the trash compactors common in retail and fast food
That last item surprises more employers than any other. The compactor in the back of a grocery store or restaurant is a piece of equipment a 16-year-old cannot legally operate. Violations of the federal hazardous occupation rules carry civil money penalties that can reach tens of thousands of dollars per violation, with the DOL adjusting the amounts for inflation periodically.5U.S. Department of Labor.

Driving on Public Roads Is Banned at 16
One restriction matters especially for late shifts. Under Hazardous Occupations Order No. 2, no employee under 17 may drive a motor vehicle on public roads as part of their job. The ban is complete. It does not matter that the teen holds a valid driver’s license or only needs to cross a parking lot onto a public street.9U.S. Department of Labor. Fact Sheet 34 – Hazardous Occupations Order No. 2 – Youth Employment Provision and Driving Automobiles and Trucks Under the FLSA If a manager at a closing shift asks a 16-year-old to drop the deposit at the bank or run supplies to another location, that is a federal violation regardless of what Missouri allows.
No Work Permit Required at 16
Missouri requires work certificates for 14- and 15-year-old employees, issued by a school principal or superintendent and kept on file by the employer.10Missouri Revisor of Statutes. Missouri Code 294.045 – Work Certificates Because the child labor law targets youth under 16, the certificate requirement does not extend to 16-year-olds.3Missouri Department of Labor and Industrial Relations. Youth Employment You can start a job at 16 with the standard hiring paperwork any employee completes, and work whatever hours you and your employer agree on, subject only to school attendance and the federal job restrictions above.
