Traffic Message Boards and Advisory Arrows

Traffic message boards are similar to advisory arrows, except advisory arrows are usually smaller, have less electronics, and usually cost less.  Some traffic message boards have laptops that come with them to help operate them.  Advisory arrows have a photocell dimmer that allows motorists to be able to see the arrow 24 hours a day.

Typical models have left arrow, right arrow, double arrow and caution bar.  Split arrow style is also available.  These can be mounted to trucks, and magnetic mount kits are available for this.  Always research all types of advisory arrows and traffic message boards before purchasing.
