Do You Know Your State’s TMA/Attenuator Truck Regulations?

Royal Truck & Equipment seeks to ensure that our customers are kept well-informed on how to best protect their employees in the work zone. Our commitment to our customers is that we will invest the resources necessary to provide the most up-to-date information on the attenuator truck regulations that have been put in place throughout the country. Our TMA Trucks are designed and built specifically to exceed the strictest standards throughout the U.S.

Unlike many other industries where federal regulation sets the baseline operational requirements, with attenuator trucks, each state has its own regulations as to how a truck needs to be built and when it needs to be used in a work zone operation.  Our commitment to our customers is to provide the most up-to-date information for attenuator truck regulations so that you can be sure you are fully prepared before your work even begins.

As a standard rule at Royal, all of our TMA trucks are designed and built to meet and exceed each individual state’s minimum build requirements.

Arrow Board

Arrow Board Requirements

Flashing Arrow Boards are used on vehicles in mobile operations and placed at the beginning of lane closure tapers. Every state is different when it comes to the number of lamps required on your arrow board. Some states require 15 lamps, some require 25 lamps. Always check your state guidelines before ordering an arrow board.  For your convenience, we offer both options.

CDL Requirements

Each CDL classification is distinguished by the vehicle’s gross vehicle weight rating (GVWR), among other items. TMA trucks vary in weight, which can impact CDL requirements. Our TMA Trucks are weighted at less than 26,000lbs GVWR. This means that in most states, you do not need a CDL license to drive our TMA trucks. Keep in mind that the CDL classification you apply for will determine not only the type of vehicle you are allowed to drive, but also which endorsements you may be required to obtain.

DPF Problems

DPF Requirements

With increasing needs to reduce emissions comes advancements in regulations. New technology has changed the way trucks are engineered and driving and maintaining them requires a new set of skills relative to new technology. The DPF traps the exhaust particulates, and it is not a disposable item – a new one could several thousand dollars. Do you know what to do when the DPF lights come on?  Learn more with our guide.

Virginia DOT Requirements – updated 11/13/2020

The 2011 Virginia Work Area Protection Manual (Standards and Guidelines for Temporary Traffic Control) with Revision 2 contains the most current standards, guidance, options, and support for the design, application, and placement of Temporary Traffic Control Devices on roadways in Virginia. The guide was revised in September 2019 and became “effective on all projects advertised on or after January 1, 2020”.

VDOT has recently started enforcing these regulations.  One of these regulations stipulates that “the rear panel of the TMA cushion shall have alternate 6 to 8-inch wide orange and black or yellow and black chevron (inverted v) stripes. Stripes shall be sloped at a 45 degree angle downward in both directions from the upper center of the rear panel. Fluorescent orange or yellow retroreflective sheeting shall be in compliance with Section 247 of the Road and Bridge Specifications.”

New York Work Zone Camera Systems – updated 3/11/2021

Recent projects in New York State have called for constantly recording cameras in the work zone to capture vehicles that pass the zone. At a high level, these specification requirements include solid-state high resolution cameras capturing up to 24 hours a day, 7 days a week, while the operation is ongoing. Additional requirement details specify storage and memory, resolution, accessibility, and post-impact event procedure. With work zone collisions and intrusions still occurring at a high rate, these guidelines help capture and provide critical insights for review and analysis when there’s an accident in a work zone.
