Trucking has become high-tech with required electronic logging devices (ELD) and GPS systems. These safety measures record hours of service to prevent driver fatigue and pinpoint the truck’s location, which could be critical in an emergency. These are five of the most important parts of a semi-truck, but many others are things all drivers must maintain on their vehicles.
Wheels and Tires
Dented or damaged rims can lead to tire failure, as can improper inflation or wear from driving on tires past their useful tread life. We’ve all seen the remnants of blown-out truck tires in the middle of the road. Experienced truckers know that investing in quality tires pays off in the long run. Skimping on tires can result in costly accidents. In a worst-case scenario, tire failure can cause a driver to lose control, fishtail, or roll, possibly colliding with other vehicles, barriers, or trees.
Brakes
Semi-trucks are enormous and require heavy-duty brakes to overcome inertia—Newton’s first law of motion. A body in motion tends to stay in motion unless an outside force changes that. Truck brakes need maintenance and replacements more frequently than passenger cars. Modern truck brakes are complex systems of drums, brake pads, discs, springs, and compressed air that work together to engage and disengage the mechanism that stops the vehicle. All parts should be checked regularly for wear. In the case of air brakes, truckers should check for leaks that reduce the braking system’s effectiveness.
Lights
Sundown is not the time to discover your lights aren’t working. This goes not just for a semi-truck’s headlights, but also brake lights, rear lights, and any other lights required to illuminate the truck’s exterior for other drivers’ visibility. Stick with the truck manufacturer’s recommendations regarding what type of lights to install when replacements become necessary.
Seats
Commuters in passenger vehicles understand the importance of a comfortable seat. Now multiply that by an additional 8-10 hours behind the wheel, and you’ll understand how critical a supportive, comfortable truck seat is to professional drivers. A good seat is adjustable fore and aft, up and down, and reclinable. Truckers can be passionate about their seats, and many choose aftermarket semi-truck seats with additional features like cooling, heating, or adjustable armrests.
Mirrors
Most drivers learn that if they can’t see a truck’s mirrors, the trucker can’t see them. Mirrors are among the most important parts of a semi-truck. A good set of mirrors that provides a clear view of lanes on either side of the truck is critical for trucking safety. Lane changes and reversing rely on mirrors to give drivers notice of obstacles and other vehicles. Clean mirrors are essential, and cleaning them regularly can save lives.
