How long is a semi-truck?

Combining the tractor and trailer, a standard semi-truck's length is about 70 feet long.

The length can vary considerably, though, based on a variety of factors.

1. Type of tractor.

• Day cabs are typically 20 feet long, though each manufacturer and spec can alter that.
• Sleeper cabs, which have a bed inside for drivers who haul over-the-road, are also around 20 feet in length.
  

2. Type of trailer.

• A standard dry van trailer is 53 feet long. It overlaps a few feet over top of the tractor, making the unit about 70 feet.
• Pup trailers are typically 28 feet in length. It is common to see two pup trailers pulled together, making for a total length of around 56 feet.
• Intermodal containers are typically 20 or 40 feet long but can also reach the standard 53 feet.
• Tanker trailers, flatbeds and a variety of other trailer types all range between 48-53 feet.
• Extendable double drops and Removable Goosenecks (RGN) are some of the longest trailers available. Both reach 80 feet long when fully extended and typically carry other vehicles and large equipment.

3. State requirements.

Companies can often get creative with the length of their equipment for specialty freight needs, but each state has different regulations for overall length.

While Texas and Oklahoma allow trailers to be 59 feet long, most states cap trailer length at 53 feet.

How tall is a semi-truck?

A standard semi-truck's height is about 13 ½ feet tall.

The height of a semi-truck depends on various factors.

1. Type of tractor.

• Most tractors, sleeper or day, reach 13 ½ feet tall when including the height of the wind fairing.
• Cabs themselves range anywhere from 6-10 feet tall depending on their make and model.

2. Type of trailer.

• Standard dry van trailers are typically 13 ½ feet tall in total, with the door height making up 9 feet of that.
• Flatbed trailers are typically only 5 feet tall, but can hold cargo around 8 ½ feet tall.
• Intermodal trailers are typically 9 ½ feet tall, as they must adhere to standards for railways as well as roads.
• Less standard trailers, like step decks and double drops, go as low as 3 ½ feet and 1 ½ feet tall, respectively.

Defining semi trucks

Semi-trucks: despite their heft and size, it&#;s a wonder they&#;re called semi.

Before we explore the many different types of semi trucks on the market, we first want to understand what we mean when we say &#;semi&#; truck.

A semi-truck refers to a combination of two components:

1. The tractor unit (which is where the truck&#;s cab is located)
2. The trailer unit (which is attached to the tractor)

The truck area is where passengers sit, and the trailer area is where heavy equipment and goods are stored and transported.

The cool part about semi-trucks is that there&#;s one for virtually every need! With our newfound knowledge, let&#;s find out what our friends in the trucking industry have built.

We&#;ll explore the most common types of semi-trucks on the market in the next section.

The most common types of semi-trucks

The most common types of semi trucks on today&#;s market include:

• Day cabs
• Sleeper trucks
• Custom haulers
• 18-wheeler trucks
• Sloped-nose trucks
• Conventional-nosed trucks
• Trucks with raised and flat roofs

Day cab semi trucks

Day cabs are some of the most standard semi-trucks on the market. These trucks contain an area for drivers and passengers to sit, and they may be equipped with rear windows.

Because they don&#;t have a sleeper cabin attached, operating in reverse tends to be easier. Day cabs are often used for shorter trips that don&#;t require overnight hauls.

These types of budget-friendly semi-trucks have shorter bodies and are easier to drive in narrow areas. Best of all, almost any trailer can attach to it, making it one heck of a desirable commercial truck.

Sleeper semi trucks

If you&#;re looking for a semi-truck that can be taken on the road for days at a time, a sleeper semi-truck is the truck for your business.

Sleeper semis are built with sleeping quarters, helpful accessories, and other luxurious amenities. These trucks help people accomplish tasks for over-the-road hauling.

These trucks come in a variety of different sizes and styles. You can choose a simple sleeper truck with a basic sleeping area. Or, opt for an extended sleeping area with a full RV setup.

Like the day cab, a sleeper truck can be hooked up to a variety of trailers. Because of its flexibility and comfortable sleeping compartment (among other benefits), a sleeper semi-truck is a solid over-the-road truck.

Custom hauler semi trucks

Like its namesake, custom haulers are different from standard trailers and tractors.

If you want a specialized tractor with heavy-duty towing capabilities, say the word. With custom haulers, heavy lifting can be done. With custom haulers, you can even add sleeping quarters to the truck.

The benefit of opting for a custom hauler is that custom haulers tend to have some of the most powerful engines on the planet. These trucks help transport oversized loads and different types of cargo across long distances.

Defining semi-trailers

&#;So, why is the word &#;trailer&#; used with the word &#;semi-truck?&#;&#; you might ask. Great question.

Instead of calling a truck a semi-tractor semi-trailer truck, we just call the combination of the tractor and trailer a &#;semi-truck&#; (also known as tractor-trailer).

While we&#;re on the topic, semi-trailers are what we call the trailers attached to the tractor. Semi-trailers have one job (and one job only): to haul distinct goods.

Fortunately, trailers come in a variety of sizes and shapes. For example, some carry refrigerated goods, and others carry livestock. Hook a liftgate up to one of them, and you&#;re all set to load and unload goods for most jobs.

Different types of semi-trailers

Different semis use different trailers. As a result, becoming familiar with the most common types of semi-trailers can help you with your fleet operation.

The most common types of semi-trailers include:

• Belt trailers
• Drop deck trailers
• Dump trailers
• Flatbed trailers
• Grain hoppers
• Lowboys
• Sliding axle and hydraulic tail trailers
• Tank trailers

While not an exhaustive list, these are some of the most common semi-trailer types on today&#;s market. Find the right one for your fleet operation, and you&#;ll be well on your way to running a successful fleet operation.
