Are California Meal and Rest Break Rules Applicable To Interstate Truck Drivers?

August 26, 2025 Legal Team

California’s meal and rest break rules provide strong protections, but interstate truck drivers face federal preemption under FMCSA regulations. Preemption means that when federal and state laws conflict, the federal law overrides the state law. As a result, most drivers who cross state lines must rely on federal rules, not California’s laws.

The Preemption Issue

In 2018, the FMCSA determined that California’s meal and rest break laws are preempted for property-carrying commercial drivers subject to federal hours-of-service regulations. The agency concluded that California’s rules:

  • Were incompatible with federal hours-of-service regulations.
  • Created an unreasonable burden on interstate commerce.

This decision meant that many interstate truck drivers could no longer claim California meal and rest break protections when covered by federal law.

California Meal and Rest Break Rules

California requires most employers to provide:

  • Meal breaks: A 30-minute unpaid meal break if an employee works more than five hours in a day. A second 30-minute meal break if the employee works more than 10 hours.
  • Rest breaks: A 10-minute paid rest break for every four hours worked or “major fraction” thereof.

If an employer fails to provide these breaks, the worker is entitled to one hour of additional pay for each day a meal period or rest period is denied. These rules are strictly enforced across most industries.

Federal Regulations for Interstate Truck Drivers

Most truck drivers fall under federal law, specifically the Federal Motor Carrier Safety Administration (FMCSA) regulations. These rules limit the number of hours a driver may operate and mandate rest periods to protect public safety.

Federal Regulations for Interstate Truck Drivers

Key FMCSA rules include:

  • A maximum of 11 driving hours after 10 consecutive off-duty hours.
  • No driving after 14 consecutive hours since coming on duty.
  • A 30-minute rest break required after eight cumulative hours of driving.

Even though California’s meal and rest break laws are preempted for many interstate drivers, employers must still comply with federal regulations. Violations of those rules can form the basis of legal claims for unpaid wages, safety violations, or wrongful termination.

Court Challenges

Truck drivers’ advocates and labor organizations challenged the FMCSA’s preemption determination in federal court. In 2021, the Ninth Circuit Court of Appeals upheld the FMCSA’s decision, ruling that California’s meal and rest break rules do not apply to drivers governed by federal hours-of-service rules.

As a result, interstate truck drivers who cross state lines and fall under FMCSA regulations are generally not entitled to California’s separate meal and rest break protections. 

Truck Drivers Who May Still Qualify for California Break Rights

Not all drivers are exempt from California’s laws. The federal preemption applies primarily to interstate property-carrying drivers subject to FMCSA rules. Employees who may still benefit from California’s meal and rest break laws include:

  • Intrastate drivers: Drivers who operate only within California and are not subject to FMCSA interstate regulations.
  • Passenger-carrying drivers: Such as bus drivers, who may be governed by different standards.
  • Local delivery drivers: Who remain within California and work for employers covered by state law.
