Explanation
Construction/Maintenance Signs & Signals. Various traffic control devices are used in road construction and maintenance work areas to direct drivers and pedestrians safely through the work site. Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in the construction zone. (Signs will indicate where speeding fines will be doubled when workers are present).
