Arrow Boards

The arrow board is the device drivers obey first — a lit arrow visible a mile away telling them to merge, now. Every lane closure on a higher-speed road needs one, and it has to be the right type, in the right place.

What it is

Understanding arrow boards

An arrow board (flashing arrow panel) is the high-visibility electronic device that directs traffic to merge out of a closed lane. The MUTCD defines the types — with full-size Type C panels required for high-speed roadway closures — plus the display modes: merge arrows for closures, and the caution bar or four-corner mode for shoulder work where no merge is intended. Using an arrow where a caution display belongs sends drivers the wrong message, so mode discipline matters as much as the hardware.

Our arrow boards deploy as part of the closure itself: positioned at the start of the taper, at the height and brightness the standard requires, with the correct display for the operation. For mobile work — striping support, pothole patching, sweeping — truck-mounted or towed panels move with the operation.

Scope

What's included

  • DOT-compliant arrow panels matched to the road class
  • Delivery, positioning at the taper, and aiming/brightness setup
  • Correct display mode for the operation — merge vs. caution
  • Truck-mounted or towed panels for moving operations
  • Battery/solar service through the deployment
  • Integration with the full closure package and TCP

How we execute

From call to close-out

01

Right panel, right road

Panel type and size are matched to the roadway speed and the state DOT's requirements — full-size panels for freeway-class closures.

02

Placement at the taper

The board is positioned at the beginning of the merging taper, aimed at approaching traffic, at the mounting height and intensity the standard calls for — day and night settings verified.

03

Mode discipline

Merge arrow for closed travel lanes; caution display for shoulder work. Our crews set and check the mode with every zone change, because the wrong display trains drivers to ignore the board.

FAQ

Arrow Boards — common questions

When is an arrow board required for a lane closure?
As a rule: whenever a travel lane is closed on a multi-lane road, and on any higher-speed roadway. State DOT standards specify panel type by road class. If you tell us the road and the operation, we'll confirm what the standard requires.
What's the difference between merge arrow and caution mode?
The flashing arrow tells drivers to leave the lane — it's only for closed travel lanes. The caution display (bar or four corners) warns without directing a merge, which is what shoulder work requires. Using the arrow for shoulder work causes unnecessary, unsafe merging.
Do you provide arrow boards for mobile operations?
Yes — truck-mounted and towed panels that move with sweeping, striping support, patching, and similar operations, crewed and coordinated so the protection vehicle stays correctly positioned behind the work.
Can I rent an arrow board by itself?
Yes. We deliver, position, and service standalone units. Most clients pair rental with our setup service so the placement and display mode are compliant from hour one.
