Over the past decade, there’s been a significant rise in spending on highway construction and maintenance, culminating with the 2021 Bipartisan Infrastructure Bill allotting $110 billion to improving our nation’s aging infrastructure. With Americans generally driving more than ever, completing construction and maintenance operations as safely and efficiently as possible has never been so important. Let’s learn more about the driving force behind the maintenance of traffic: the traffic control truck.

What is a TMAs (Truck Mounted Attenuators) ?

Also known as a pattern truck, cone truck, safety truck, or MOT (maintenance of traffic) truck, this type of vehicle is critical for road maintenance operations. A traffic control truck mainly serves to facilitate sign and cone placement when closing travel lanes in order to perform road work. These trucks are outfitted with an arrow board that visually warns travelers of changing traffic conditions.

What Safety Features are Typically on a Traffic Control Truck?

Depending on the operation, the type of traffic control truck and equipment needed may differ and body designs can vary widely to accommodate different types of operations. Some of the determining factors include:

  • Size of the operation: Are you closing several miles or a few hundred yards of roadway? Answering this question will steer you in the right direction of what size body is needed when comparing traffic control trucks. If you frequently perform large-scale operations, you would likely opt for a truck with a longer bed and taller racks to securely transport your traffic control devices to and from the work zone.
  • Work zone location: The difference in traffic control trucks used for highways with higher speed limits versus local roadways with lower speeds is significant. If your operations are typically not on the highway, a specially designed man basket mounted on the rear of a smaller class truck (e.g. class 2 or 3) may be an appropriate solution.
  • Traffic control device type: Depending on which state you operate in, you may be required to use a specific kind of traffic control device, with cones and barrels being the most frequently used. To increase your team’s efficiency, you should aim to use a rear basket tailored to the specific devices you use.

What Makes Using Traffic Control Trucks the Safer Option?

These types of trucks are specially designed for traffic control and maintenance operations. Alternative options are very unsafe and a liability for your company with higher risk of injuries and fatalities. When using an improper truck to perform a lane closure, crews may be faced with performing the task one of two other highly dangerous ways.

  • On foot: By placing and retrieving cones on foot for a lane closure operation, workers are completely exposed to oncoming traffic with little to no safety. Not only does this make your operation less efficient, but it also makes it significantly more dangerous. Between 2017-2019, 45.3% of fatalities in work zones were workers on foot struck by vehicles. With no form of protection, a work zone intrusion could result in the death of a crew member.
  • Off the back of a pickup truck: While this method is a step up from performing the job on foot, performing traffic control from the bed of a pickup truck is still a significant risk. If an intruding vehicle does hit your truck, any person in the bed is liable to be thrown into live traffic from the force of the impact.

When safety and efficiency are your primary priorities in MOT operations, not having a traffic control truck in your fleet is the easiest way to leave your company vulnerable to lawsuits and claims.
