What’s The Difference Between A Truck And A Semi? (Classic Road Rage)

Have you ever seen giant vehicles operating on the road and wondered what are they?

The thing that confuses the people most is that they can’t seem to differentiate between a semi and a truck; here’s everything you need to know about it.

A truck is a vehicle with four to 18 wheels. On the other hand, a “semi” is a trailer that is pulled by a truck.

If you want an in-depth overview of trucks and semis, hop on this ride and let me drive you through it. And read this blog post till the end.


A truck is a giant vehicle that is used to transport goods and materials. Trucks carry out general transportation tasks inter-city and intra-city.


A trailer that is pulled by a truck is known as a “semi.” A semi-truck has two parts: a tractor unit and a semi-trailer. Since there are no wheels in the front of the semi, its reliance is on the tractors.

Different countries use different terms for semi-trucks. Canadians call it a semi-truck, while semis, eight-wheelers, and a tractor-trailer are the names used in the U.S.

Truck With a Semi-trailer vs. Truck With a Full Trailer

A full trailer moves on its wheels, while a semi-trailer is detachable and can only operate with the support of a truck.

Semi-trailer trucks are often used in the transportation of goods, while full-trailer trucks are mainly used to transport heavy equipment. The interesting fact about semi-trailer trucks is that you can haul two separate loads on them simultaneously, while full-trailer trucks can only haul one load at a time.

Do Semi-trucks Ruin Roads?

Semi-trucks are a common sight on our roads. They can be seen hauling goods, so they’re often the first thing people think of when they hear the word “truck.”

Semi-trucks are bad for roads. It’s not just that they cause more damage than other types of vehicles, but also because they are more powerful and heavier than passenger cars.

Trucks also have a longer lifespan than passenger cars, which means that they’re used for long periods on the road. This means that trucks generate more wear and tear on the road over time.

What Do Semi-truck Drivers Eat in America? 

Study shows that only 24% of truck drivers have normal weight, while 76% are overweight due to their wrong eating patterns.

A semi-truck driver can burn around 2000 calories. So, it’s really important for truck drivers to eat healthy and engage in physical activities.

Here’s a healthy food chart for American semi-truck drivers:

  • Breakfast: 7-8 hours before departure, have a high protein breakfast that contains carbs and fat.
  • Lunch: 4-5 hours before departure, have a light lunch that’s low in carbs.
  • Dinner: 2-3 hours before departure have a light dinner that’s low in carbs.
  • Snacks: During the day, semi-truck drivers can snack on fruit or vegetables as they see fit. At night, they should avoid snacking after dinner because it will make them feel hungry again in the morning.

How Long Does A Semi Driver Need To Sleep? 

When it comes to the amount of sleep recommended for American semi-truck drivers, there is no standard number because it depends on many factors such as age, gender, and level of physical activity.

According to the Sleep Foundation, adults should get between 7 and 9 hours of sleep per day.

Why Are There Spikes on Semi-wheels?

Made out of thin plastic, chrome-painted spikes are lug nut covers that keep them safe from wear and tear. 

Semi-truck wheels are designed to best withstand the wear and tear of heavy-duty trucking. The spikes on semi truck wheels function as a protective measure, helping to prevent the rim from getting damaged or worn out.

It’s worth mentioning that many people confuse these plastic spikes with steel spikes. They’re chrome painted, therefore they appear to be made with shiny steel. 

How Much Fuel Does a Semi-truck Consume?

A semi-truck can go seven miles per hour while one tank can hold up to 130 to 150 gallons. Make sure to never fill the truck to the top to eliminate the risk of spilling and diesel expansion. 

The fuel consumption of a semi-truck is measured in miles per gallon, and the average fuel consumption for a semi-truck is around 6 to 21 mpg. For comparison, an average car only gets about 25 mpg.

The fuel semi-trucks consume when idle ranges between ½ and ¾ gph. 

The reason for high fuel consumption is that semi trucks are very heavy and have large engines that need to be able to handle the weight of the vehicle as well as all of its cargo. 

Semi-trucks also have large rear axles that make up most of the weight and force them to use more fuel than other vehicles because they have to compensate for their extra weight by using more power from their engines.

There’s no doubt that semi trucks are huge. 

Despite this, the real question is “why do semi-trucks need to be such a huge size?” It’s not just about the length, but also the weight and payload of the truck.

The answer is that they’re designed to haul big items. The semi-truck also decreases the cost of transportation as it can efficiently carry the load that 10 trucks would with increased cost. 

A trailer attached to a truck weighs anywhere between 30,000 and 35,000 pounds. 

U.S. Federal Law only allows you to load a semi-truck with up to 80,000 pounds.
