Truck drivers work long hours, face tight deadlines, and often have rigorous schedules. Drivers often suffer from a lack of adequate sleep, extended work hours, and mental or physical exertion, all of which can impair their driving performance. Is it any wonder that one of the most dangerous causes for truck accidents is driver fatigue?
Fatigue is more than just feeling tired—it’s a state of physical or mental exhaustion that impairs reaction time, decision-making, and overall driving performance. According to the Large Truck Crash Causation Study (LTCCS), 13% of commercial motor vehicle (CMV) drivers involved in crashes were considered fatigued at the time. [Source: FMCSA]

The Federal Motor Carrier Safety Administration (FMCSA) published this list of practical tips to help drivers better manage fatigue on the road.
Getting enough sleep before getting behind the wheel is essential. Drowsiness slows reaction time and increases the risk of accidents.
Did You Know? FMCSA studies show that time of day affects alertness more than time-on-task. Most people are less alert at night, especially after midnight. This drowsiness may be enhanced if you have been on the road for an extended period.
A balanced diet and consistent meal schedule support better sleep and sustained energy.
Did You Know? A study conducted on the sleeping and driving habits of commercial motor vehicle (CMV) drivers concluded that an unhealthy lifestyle, long working hours, and sleeping problems were the main causes of drivers falling asleep while driving.
Short naps taken proactively can boost alertness and performance more effectively than naps taken when a person is already drowsy. The ideal time for most drivers to nap is early afternoon (between 1-3 p.m.) as it aligns with the body’s natural circadian dip in alertness.
Tip: Aim for naps between 10 to 30 minutes to avoid sleep inertia, the groggy feeling that can occur after longer naps. Short, controlled naps can restore alertness without leaving you sluggish or disoriented.
Avoid driving after taking medications that may cause drowsiness—especially common cold remedies.
Did You Know? Cold pills are one of the most common medicines that may make you drowsy. If you must drive with a cold, it is safer to suffer from the cold than drive under the effects of the medicine.
Know the Warning Signs of Drowsiness.Watch for frequent yawning, heavy eyes, and blurred vision.
Did You Know? Research shows that being awake for 18 hours is equivalent to a BAC of 0.08%, the legal limit for intoxication.
Alertness tricks are things like turning up the radio, drinking coffee, and opening the window. These offer a false sense of alertness and don’t last very long.
Tip: If you feel yourself fading, the safest option is to pull over and take a short nap or rest break. Even a 15-minute pause can restore alertness far more effectively than relying on temporary stimulants like caffeine or loud music.
Bonus Insight. Studies show that “alertness tricks” only mask fatigue for a short time. They don’t improve reaction time or decision-making, which are critical for safe driving—especially in high-risk situations.
The Federal Motor Carrier Safety Administration regulates and monitors trucking companies throughout the United States, setting forth regulations governing commercial motor vehicles and trucking companies.
To protect drivers and the public, the FMCSA enforces Hours of Service (HOS) rules that limit how long truckers can drive and work.
Within the FMCSA Regulations are a set of rules referred to as Hours of Service (HOS). These regulations govern commercial truck drivers and the hours they work and drive.
