An example of workzone traffic protective equipment is which of the following?

Truck-mounted crash cushions are specifically designed to protect workers and road users in work zones. These devices absorb the impact from vehicles to prevent injuries and fatalities during an unexpected collision. They are strategically placed to absorb the energy of a crashing vehicle, providing a crucial safety barrier at work zones where construction activities may obstruct normal traffic flow.

While cones, hay bales, and signage are important elements of work zone traffic control, they serve different purposes. Cones are primarily used to delineate safe paths for vehicles and pedestrians, while hay bales are often used as temporary barriers but do not offer the same level of protection as crash cushions. Signage informs drivers of the work zone and any detours or changes in road conditions but does not physically protect against collisions. Thus, truck-mounted crash cushions are a distinct form of protective equipment specifically engineered to enhance safety in work zones.
