Semi Trucks: Numbers You Never Knew! (22 Questions Answered)

The trucking industry is crucial to the US economy. Like the taxes that we pay to the government, semi trucks are also the lifeblood of a country.

The majority of industries rely on the products shipped by a semi truck. These products include fuel, food, healthcare, construction supplies, and a lot more. 

Without semi trucks, any state would be in so much trouble.

If you want to be part of the trucking industry, the following facts and statistics might interest you. 

How Long have Semi Trucks been Around?

Semi trucks have been around for 123 years. It was first invented in 1898 by Alexander Winton when he felt the need to have a larger vehicle to transport his manufactured cars across the US. He started selling semi trucks in 1899, but it took him a while to be noticed by other car manufacturers.

Five years later, the trucking industry had only sold 700 semi trucks. But it increased in 1914 with 25,000 units sold.

How Far can Semi Trucks Drive?

In general, a semi truck with a full tank of 300 gallons and a fuel consumption rate of mpg of 7, can drive up to 2,100 miles. However, if we consider the 11-hour driving limit imposed by FMCSA, say a driver can travel 64 miles per hour, a truck can drive a maximum of 715 miles.

But realistically speaking, no driver can drive 11-hours straight. Any driver needs at least two hours to cater personal necessities and for unloading or loading of cargo.
