What is the minimum overlap required for impact barrels over fixed objects on the traffic side?

• A. 30 inches
• B. 12 inches
• C. 24 inches
• D. 36 inches

Answer: (A)

The minimum overlap required for impact barrels over fixed objects on the traffic side is indeed 30 inches. This requirement ensures that the impact barrels provide adequate protection against vehicles colliding with fixed obstacles, such as guardrails, concrete barriers, or other structures. By having a 30-inch overlap, the barrels are positioned in a manner that allows them to effectively absorb the energy from an impact and reduce the likelihood of a vehicle striking the fixed object directly. This overlap is crucial for maintaining safety on roadways, particularly in work zones or areas where drivers may be diverted around obstacles. Proper installation and configuration of traffic control devices, including the placement of impact barrels, are vital for the protection of both road users and workers in the vicinity.
