Mounted vs Trailer Message Boards: The Logistics Tradeoff

A message board on the truck moves with the crew; a trailer board can be dropped and left. Each choice changes how a fleet stages and moves equipment. Here is how to decide.

Changeable message signs come two ways: mounted on the truck or towed on a trailer. Both display the same warnings, but they change how a fleet operates. The right pick depends on how your crews stage, how often they relocate, and how many boards each job needs.

Mounted boards

• Travel with the truck, so the board is always where the crew is
• No separate unit to tow, drop, or retrieve
• One power and control system integrated with the truck
• The board is tied up whenever the truck is deployed elsewhere

Trailer boards

• Can be dropped at a location and left for the duration of a job
• One truck can place several boards across a corridor
• Positioned independently of where the truck parks
• Requires towing, staging, and a separate maintenance and charging routine

Matching the choice to the work

Mobile crews that move often lean toward mounted boards that stay with the truck. Long-duration closures or corridor jobs that need several signs favor trailers that can be dropped and left. Many fleets run a mix, keeping mounted boards on the TMA trucks and a set of trailers for larger setups.
