What type of signage is typically used in TTC?

Answer: B — Warning and regulatory signs

The use of warning and regulatory signs in Temporary Traffic Control (TTC) is critical because they inform drivers about unexpected changes in roadway conditions, restrictions, and potential hazards in work zones. Warning signs alert motorists to the presence of construction or maintenance activities, advising them to slow down and stay alert for personnel and equipment on the road. Regulatory signs, on the other hand, provide instructions that must be followed, such as detour routes, lane merges, or speed limits through the work zone. Together, these signs play an essential role in maintaining safety for both workers and drivers by conveying necessary information that helps in navigating through altered traffic patterns. This is crucial for preventing accidents and ensuring that all road users are aware of their surroundings. The other types of signage listed do not fulfill this primary safety role within work zones.
