Vehicle breakdowns are never pleasant, but are especially problematic for semi-truck drivers with time-sensitive deliveries and pickups. Some breakdowns cannot be predicted, and towing companies will help with recovery and repairs. However, you can typically avoid malfunctions with proper maintenance. Here are a few ways to avoid issues on the road.

4 Common Sources of Semi-Truck Breakdowns

1. Brakes

Failing brakes account for nearly 30% of semi-truck accidents. Since commercial vehicles log miles more quickly than cars for personal use, pads wear out at faster rates. Semis also experience brake hose air leaks that decrease pressure and functionality.

To stay safe, schedule brake service if you hear unusual noises, which typically point to worn pads.

2. Tires

The weight of assorted products and equipment puts pressure on semi-truck tires, causing them to deflate. Deflated tires make more contact with the road, causing increased friction and wear. Underinflated units also let heat build up in the sidewalls, which can cause blowouts. Lack of tread depth increases the blowout risk as well.

To prevent these issues, routinely check the psi (pounds per square inch) of the wheels with a pressure gauge tool. This is particularly important before long trips.

3. Battery

Driving in colder regions of the country, including Wisconsin, subjects a semi-truck’s battery to performance issues. Battery life decreases by 20% in freezing temperatures, and by 50% at -22 degrees Fahrenheit. Without a functional power source, electrical components like the alternator, lights, and starter motor won’t work. A towing service may be able to replace or recharge the battery to get you back to work.

4. Engine

If you drive an older semi that hasn’t received regular maintenance, you’ll deal with engine problems. Older engines get overtaxed quickly compared to newer models, frequently experiencing efficiency issues that impact fuel economy.

If you notice differences in gas mileage, have the engine inspected for potential malfunctions to prevent breakdowns.
