There are all types of accidents and damages that happen on roads all over the world. These are events that cannot be predicted or even avoided as they tend to happen at unexpected times and locations. Some of these damages that happen to the guard rails and roads can be reduced by the use of proper signage, clear and visible road signs and the use of protective vehicles that may have attenuators mounted on them.

In most cases, these protective vehicles are used to safeguard numerous workplaces and workers from badly driven vehicles. These protective vehicles can also have signage devices to warn other drivers of accidents or upcoming conditions. Trucks and trailers are the two types of vehicles that are used as protective vehicles that have attenuators mounted on them. Each of the two vehicles has unique benefits and limitations, and this discussion focuses on highlighting this vital information to assist you to select the most appropriate vehicle when hiring:  

Truck with a mounted attenuator


  • In case a car crashes into the attenuator, the attenuator can easily be hosted and secured to the truck and transported to the repair shop for a replacement, which eliminates the need for hiring a tow truck.
  • It does not experience any tyre downtime or maintenance as its tyres rarely have any issues.
  • It is easier to manoeuvre and back the truck.     


  • The truck may have an extended downtime after the attenuator experiences an impact, which may be disadvantageous if you have a limited number of operational protective trucks.
  • The maintenance and replacement of the attenuator are high.
  • Removing the attenuator is a complex process, which limits the truck from engaging in other activities.
  • The immense weight of the attenuator may damage the truck's suspension as well as a decrease in the stability of the truck.  

Trailer with a mounted attenuator


  • The attenuator mounted on trailers has few parts, making the mounting process easier.
  • Trailers have a low attenuator assembly and maintenance costs
  • Since the attenuator is mounted on a secondary section, it can be detached after an impact and enable the trailer to engage in other activities such as cargo hauling.
  • Various trailers can use the attenuator, as it is not permanently attached to a single trailer, unlike with the truck.


  • After an impact, maintaining and replacing the attenuator can be expensive and reduce the profit margins of your business.
  • Manoeuvring the trailer can be difficult, especially when reversing around a corner, so it is recommended that the driver seeks the assistance of a spotter.
  • Because trailers are long vehicles, it can be hard to turn it around if the driver is on a narrow or small road.
  • The trailer must be driven carefully at all times to avoid the attenuator from shifting to the next lane and causing an accident.
