An arrow board's whole job is to be seen and understood from far enough away that a driver has time to merge before reaching the closure. MUTCD ties the required board class to posted speed: the faster the road, the longer the legibility distance has to be, which usually means a bigger board with more lamps.
Solar has become the default power source for most boards sold today. It skips the generator noise and fuel runs, and a fully charged unit can usually hold a display through a multi-day closure without intervention, weather depending.
Mount type is a separate decision from board class. A trailer-mounted board tows into place and sits for the duration of the job. A truck-mounted board rides on a shadow vehicle and moves with mobile or rolling operations, like striping or sweeping.

What to specify
Arrow board pricing varies more by class and mount than any other product line here, so exact specs get confirmed on the call rather than listed as one-size numbers.

Arrow board questions
What is a solar arrow board?
A trailer-mounted or truck-mounted panel of amber lamps that displays an arrow, flashing sequence, or four-corner warning pattern to direct traffic around a lane closure. Solar models charge off a roof panel instead of running off a generator or vehicle battery, which is the more common setup on longer jobs now.
What size arrow board do I need?
MUTCD groups arrow boards into classes by minimum legibility distance and lamp count, with the required class tied to posted speed. Lower-speed shoulder work can use a smaller board; higher-speed highway closures need a class rated for longer sight distance. Tell us your road's posted speed in the notes field and we'll confirm the right class.
Do I need a trailer-mounted or truck-mounted board?
Trailer-mounted boards can be towed into position and left unattended for the duration of a closure. Truck-mounted boards (often on a shadow vehicle) move with traffic and are common on mobile or moving operations. Most one-off lane closures use a trailer-mounted board.
