Yes, truck drivers in Missouri must take breaks as required by the Federal Motor Carrier Safety Administration (FMCSA). Breaks fall under federal Hours of Service (HOS) regulations, and truck drivers must take a 30-minute break after 8 cumulative hours of driving without a minimum of a 30-minute interruption.
Federal Hours of Service Break Requirements
As per the Federal Motor Carrier Safety Administration (FMCSA), truck drivers are mandated to take a 30-minute break after 8 hours of driving. This means they can be off-duty, in their sleeper berth, or on-duty not driving.
After 11 hours of driving or 14 hours on-duty, truck drivers are also required to take 10 consecutive hours of rest off-duty. Truckers are also forbidden from driving beyond a 14th consecutive hour after they come on duty. The only exception to this is for any truck driver in Missouri who operates within a 150 air-mile radius and returns to their starting location.

Split Sleeper Berth Rules in Missouri
Interstate truck drivers in Missouri are allowed to split their required 10-hour breaks into two periods. One of those periods need to be at least 7 consecutive hours spent in the sleeper berth that is paired with another break that is either taken off-duty or in the sleeper berth of at least 2 hours. Neither of these periods will count against the 14-hour limit for the driving window.
Break Rules for Local or Intrastate Drivers
Hours of service rules governing trucker rest breaks in Missouri are the same as the ones set by the FMCSA. For an intrastate truck driver, which is one who drives only within Missouri, they still are required to take a 30-minute break if they drive more than 8 hours. They also can't drive after 11 hours of driving or 14 hours on duty, and must follow that with 10 hours off.
What Happens When Truck Drivers Violate HOS Regulations
Driver and trucking company liability for break rule violations is easy to prove through electronic logging devices (ELDs) in the event of an accident. If either the trucker or the trucking company does not abide, there are huge fines, temporary suspensions, and lowered safety ratings, not to mention legal issues if these violations resulted in an accident. Learning about what are common jackknife truck accident causes and injuries and how do blind spots cause truck accidents can help you understand how fatigue-related violations contribute to these devastating crashes.
