5 Major Hazards for Heavy Truck Drivers

Whether a driver is behind the wheel of a fire truck, flatbed, tractor-trailer, or dump truck, every type of heavy truck presents greater roadway risks than a standard passenger vehicle. Because these trucks often carry heavy loads or hazardous materials, crashes involving them can be especially severe.

“Some large commercial trucks can weigh up to 80,000 pounds when fully loaded, and drivers who make these trips daily can easily forget how much a load affects reaction time,” said Nathan Arnold, Risk Control Manager at Safety National. “Technology, such as automatic braking systems and in-cab cameras, can help prevent crashes, but eliminating driver distractions remains critical to reducing carelessness and inattentiveness.”

The following five significant dangers can increase the risk of a crash for heavy truck drivers.

1. Speeding

Drivers should remember that posted speed limits do not account for heavy loads or changing road conditions. Traveling at higher speeds dramatically increases the distance a truck requires to fully stop and reduces a driver’s ability to react to hazards. According to the Federal Motor Carrier Safety Administration (FMCSA), speeding is the most frequent driver-related factor in fatal crashes involving large trucks.

2. Driver Fatigue

The National Safety Council states that driving after more than 20 hours without sleep is equivalent to driving with a blood alcohol concentration of 0.08%. Drivers need adequate sleep and can benefit from taking regular rest breaks throughout the day. Employers should monitor compliance with applicable hours-of-service requirements and encourage appropriate rest breaks. Because fatigue slows reaction time, drivers should also consider whether any medications may cause drowsiness behind the wheel.

3. Improper Lane Changes

Blind spots cannot be completely eliminated on heavy trucks, but convex and wide-angle mirrors, radar systems, and cameras can give drivers a more complete view. Cameras that provide a full view of the truck and trailer can also help reduce the “no-zones” where visibility is limited. Drivers can further reduce lane-change risks by:

• Signaling turns, lane changes, and interstate entrances and exits well in advance.
• Choosing a lane and remaining in it whenever possible.
• Watching for pedestrians, checking blind spots for other motorists, and anticipating drivers who may enter the truck’s path during a turn.

4. Tailgating

Maintaining more distance behind another vehicle provides additional time to stop. Cars and medium trucks need a three-second following distance, but a large truck needs at least a seven-second following distance. A large truck and trailer traveling at 55 mph can take nearly the length of a football field to reach a complete stop. Weather, lighting, and road conditions can further impact the need for increased stopping distance.

5. Distracted Driving

Cell phones, navigation systems, eating, smoking, passengers, and other in-cab distractions can take a driver’s eyes and attention off the road. These distractions increase stopping time and create opportunities for improper lane changes. Federal regulations and state laws may restrict cell phone use while driving, depending on the driver, vehicle, and jurisdiction.  In 2024, crashes involving distracted drivers were associated with at least 3,208 deaths and 315,167 injuries, including with cell phone activity specifically involved in 437 fatalities.
