Chances are that, if you’re reading this article you are on the market for a new trailer such as the ones that are offered at With an abundance of options and technical specifications that are being thrown at you, you may not know if you need a semi or full trailer. In this post, we take a look at some differences between a semi and full trailer. Use it as a guide to help you decide which trailer would be ideal for you.

Full Trailers

A full trailer has rear and front axles as well as a drawbar that’s attached to the unit. These types of trailers are typically 40 feet long and have the ability to move vertically with the hauling unit, which controls the front axles’ direction. These types of trailers are permanently connected to their respective towing vehicles and cannot be detached without some serious modifications that require money and time


A semi trailer on the other hand, does not have a front axle. In addition to that, a large part of its weight is regulated by the road tractor unit. Semi trailers also have legs which are called landing gear that are lowered to keep the trailer upright once it has been detached from the unit. The brakes of a semitrailer automatically lock up once it has been detached from a unit as well. It’s also worth noting that whenever you link two smaller size semitrailers together the total length of them cannot exceed 63 feet in general, nor can they exceed 57 feet when it comes to transporting goods on the highway.

Differences Between The Two

While it may be true that full trailers and semi-trailers can be combined with other semi-trailers to increase hauling capacity, commonly referred to as a double or triple, semi-trailers can carry much larger loads and provide a much better ratio between laden and tare weight. In addition to that, their longer cargo beds make them more ideal for carrying long materials.

In addition to that, semi-trailers provide much better traction in the snow as a result of the fact that the weight lies on the drive axles. However full trailers feature their own cab, or in others their own commercial cargo capacity, while semi-trailers need the utilization of a road tractor before it can become a cargo vehicle.
When it comes to actually driving both types of trailers, semi-trailers have a much smaller turning circle than their real counterparts. This means they are more manageable than full trailers when it comes to navigating with them.
