How should vehicles be positioned in the tapered portion of a closed lane?

In a traffic incident management context, it is crucial to maintain safety and optimal traffic flow, especially in areas where lanes are closed. The tapered portion of a closed lane serves as a transition area where vehicles are moved from a full lane to adjacent lanes or are directed to divert off the road.

Positioning no vehicles in this area is essential to allow for safe operations. This space is intended to be clear so that drivers can make necessary maneuvers without being hindered or confused by parked vehicles. Having a clear tapered portion ensures that other road users can readily see and respond to changed traffic patterns—this is particularly important in emergency situations where rapid response is needed.

In contrast, other approaches, such as parking vehicles to block the lane or positioning them alongside the lane, would create additional hazards. They could obscure visibility, lead to confusion among drivers, and increase the risk of collisions. Allowing vehicles to pass through this tapered area could disrupt the flow and complicate the situation further. Therefore, keeping the tapered portion completely clear of vehicles is critical for the safety and efficiency of incident management operations.
