Why Don the Changeable Message Signs Along the Highway Work?
Because motorists tend to become complacent to static messages, states nationwide are using changeable message signs to relay important messages. When messages appear on these signs, they are generally visible from a much greater distance than static signs. This makes motorists more prepared to read and respond to the message as they approach. If these signs are overused by providing routine or static information, they do not command sufficient attention during an emergency or other urgent situation. Usage rates vary from approximately three percent of the time in rural areas to well in excess of 20 percent of the time in urban areas. In some cases, the signs may have been recently erected or under construction and not yet operational. Although the sign structure may be in place, wiring and other connections may not be complete. If you see a problem with a changeable message sign, contact the local VDOT residency.
