What Is High Mileage for a Semi Truck

All vehicles have a lifespan determined by how much use and abuse they endure. A semi-truck’s usage is typically measured in miles. This article provides information on high mileage for semis and how to extend the truck’s life.


What is the high mileage for a semi-truck?

A typical semi-truck can last up to around 750,000 miles or more; some have hit the one million-mile mark. On average, a semi-truck drives about 45,000 miles per year. The years of use will depend on how well the truck is taken care of and how often it’s used. If the truck is well-maintained and only used for occasional hauls, it could last for 20 years or more. In contrast, a neglected truck used for frequent long-distance hauls may last only ten years. Thus, choosing a semi-truck that meets your needs for many years is essential.

How many miles are too many for a semi-truck?

For drivers of semi-trucks, 500,000 miles is considered the “breaking in” point. However, the “break-in” on a large-bore diesel engine is done at approximately 50,000 miles. With proper maintenance, semi-trucks are designed to last hundreds of thousands of miles and reach the 1.5 million mark. Drivers who treat their trucks well and keep up with regular maintenance will be the ones who are most likely to see their trucks reach the coveted 1.5 million-mile mark.

What is the highest mileage recorded on a semi-truck?

William Coe, Jr., of Tallahassee, Florida, drove a commercial truck safely for 3,001,276 miles. Coe began driving trucks in February 1986 and had no preventable accident in 23 years. The Florida Trucking Association rewarded him with the Trucking’s Top Rookie award to celebrate his accomplishment. Coe attributed his spotless driving record to three simple rules: always driving within the speed limit, never tailgating, and never driving while weary.

What is the average life of a semi-truck?

Most semi-trucks can drive around 750,000 miles or more, and some have driven over 1,000,000 miles. On average, a semi-truck drives around 45,000 miles annually, and drivers can expect about 15 years of use out of their truck. The truck’s lifespan will depend on how well it’s maintained and how many miles it’s driven per year. Even if the truck lasts only ten years, it’s still a good investment.

What is the most reliable semi-truck?

Founded in 1939, Peterbilt is one of the oldest semi-truck brands in the United States. The company is best known for its rugged and reliable trucks, used in various construction and transportation industries. PACCAR owns the Peterbilt brand, offering the most alternative fuel options of any semi-truck brand on the market. In addition to traditional diesel models, Peterbilt manufactures electric, hybrid, and natural gas trucks. As a result, the company is well-positioned to meet the needs of a changing marketplace.

The Frequency of Semi Truck Breakdowns

A recent study revealed that roadside truck breakdowns happen every 10,000 miles, meaning there is a chance of a breakdown for every hour a truck is driven. The study also found that most breakdowns occur within the first 100 miles of driving. This is likely because trucks carry heavy loads and are often improperly maintained. Truckers must be aware of the risks and take steps to prevent them from reducing the risk of a breakdown. Simple tips, such as regularly checking a vehicle’s fluids and tire pressure and paying attention to unusual sounds or vibrations, can go a long way in preventing breakdowns.

Determining a Semi Truck’s Age

While a truck’s life expectancy typically ranges between 500,000 and 1,000,000 miles, a more accurate way to determine, its age is by looking at its engine hours. The average engine lasts between 12,000 and 15,000 hours, so a truck with 19-24,000 hours is considered well-worn. However, many factors can affect a truck’s lifespan, such as the make and model of the vehicle, how well it has been maintained, and the driving it has done. Despite these variables, 24,000 engine hours is still considered high for a semi-truck. Therefore, when considering purchasing a used truck, inquire about its engine hours to avoid ending up with an unreliable vehicle.

Is Owning a Semi Truck Worth It?

There are several benefits to being a trucker, including the freedom to drive your vehicle and the opportunity to earn higher wages. Owner-operators can make more money than company drivers because they can operate for longer and control their gasoline standards. However, purchasing a semi-truck is a significant decision that requires careful consideration of cost, brand, and engine hours. By conducting thorough research and making an informed decision, you can find a truck that will serve you well for years. Rather than focusing solely on the high initial cost of a semi-truck, consider it an investment that will pay off over time.
