## SIGNS WITHIN WORK AREAS 

Barricades, vertical panels, cones, tubes, and drums are the most commonly used devices to alert drivers of unusual or potentially dangerous conditions in highway and street work areas. They are used to guide drivers safely through the work zone. At night they are often equipped with flashing or steady burn lights.
