Wyoming Trucking Rules and Regulations


Our Gillette Law Firm Talks Trucking Industry Regulations

When it comes to trucking in and across the state of Wyoming, there are rules in place that protect both truck drivers and the general public. For drivers of massive vehicles like semi-trucks, ignorance or disregard for these rules can have deadly consequences. Many accidents occur when these rules and regulations are neglected by trucking companies and truckers.

If you or a loved one has been in an accident with a semi-truck, you need an experienced Gillette tuck accident attorney on your side. Steven Titus & Associates, P.C., has taken on negligent truck companies and held them responsible for damage they’ve caused. Call us at (307) 257-7800 and see how we can get you and your family justice.

Truck Driver Fatigue Leading to Accidents

For truckers manning big rigs across the nation, a good night’s sleep is critical to pilot their vehicles in a safe manner. When drivers are fatigued, it leads to slower reaction times, which can lead to an accident. Truck drivers sometimes cannot assess their own fatigue levels accurately. Because of this, many laws and regulations are in place to try to keep drivers alert and attentive. These Hours of Service regulations include:

  • Truck drivers can only drive a maximum of 11 hours, and work a total of 14 hours after 10 consecutive hours of not driving or working.
  • Drivers must only drive for 60 total hours within 7 consecutive days, or 70 total hours within 8 consecutive days.
  • Drivers must take a 30-minute rest break within the first 8 hours of their work cycle.
  • Drivers are required keep a logbook showing their on-duty and off-duty time.

The Insurance Institute for Highway Safety (IIHS) survey of truck drivers indicates that many drivers violate federal limits and drive for longer than permitted in single stretches. Researchers with the IIHS found that truck drivers who reported violations in drive time were more likely to report having fallen asleep behind the wheel. It is not unheard of for truckers to take medications or drugs in an attempt to stay awake and alert longer.

Overloaded Trucks

The Federal Motor Carrier Safety Administration (FMCSA) has implemented stringent regulations when it comes to loading a semi-truck’s cargo. There are a few steps that truck companies need to take before sending their drivers onto the road.

  • Cargo Distribution: The truck’s cargo must be evenly distributed throughout the trailer, so no area of the truck is too heavy, making the rig unbalanced.
  • Cargo Must Be Sufficiently Secured: The cargo needs to stay in place during the drive because the moving cargo could cause the truck to fall over on a turn. Even if it doesn’t, the noise of the cargo hitting the sides of the truck would be a distraction to the driver.
  • Cargo Is Within the Allowable Weight: Each truck has a maximum weight that it is built to haul safely. The cargo should not exceed this amount.

These regulations are put in place for safety. When a truck company decides to ignore regulations, they’re also deciding to risk the truck driver’s life and the lives of everyone on the road.

Failure to Maintain a Truck

When trucking companies skip maintenance and/or cut corners, there can be deadly consequences. Since commercial vehicles can spend thousands of hours on the road each year, the resulting wear-and-tear can greatly increase the risk of malfunction. Truckers and trucking companies must routinely inspect, repair, and replace the following parts:

  • Windshield wipers
  • Air breakers
  • Trailer hitches
  • Hydraulic brakes
  • Headlights
  • Taillights
  • Tires
