Which of the following can unnecessarily increase clearance time during a roadway incident?

Selecting the appropriate measures during a roadway incident is crucial for minimizing clearance time and ensuring the safety of all involved. The correct answer highlights how creating a medical helicopter landing zone can unnecessarily prolong clearance time, especially when there's no off-road option available.

When first responders decide to close a road for a helicopter landing, it can lead to significant delays. This is because the roadway is rendered unusable while waiting for the helicopter to arrive, land, and take off, which can stretch out the duration of the incident response. If there are no alternative routes for traffic or no flexibility with the incident management plan, the overall clearance time suffers, interrupting the flow of traffic and potentially causing further complications.

In contrast, the other options can be considered tactics that generally aim to expedite the process or manage the situation effectively without necessarily lengthening the clearance time. Utilizing multiple lanes for debris removal can facilitate faster clearance as it allows for a more efficient workflow. Having redundant emergency services on-site may seem like a duplication of efforts, but it can ensure a rapid response and enhanced support, which can ultimately help in resolving incidents more swiftly. Requesting additional traffic control units usually helps in managing the scene better, ensuring safety, and can also assist in speeding up the clearance process by directing
