What is the purpose of a buffer zone in a work zone?

• A. To provide space between moving traffic and workers/equipment, increasing reaction time and reducing contact risk.
• B. To store equipment
• C. To allow vehicles to park
• D. To improve aesthetics

Answer: (A)

A buffer zone is safety space that separates moving traffic from workers and their equipment. This zone gives drivers a clear boundary and extra room to see warning signs, slow down, and react to any unexpected situations, which reduces the chance of a vehicle crossing into the work area. It also shields workers and equipment from direct contact with traffic, providing a safer area for workers to operate and for operators of machinery to move without encroaching on live traffic. It’s not meant for storing equipment, parking vehicles, or improving appearance; its purpose is to enhance safety by creating a protective margin around the work zone.
