Which steps should you take to preserve a roadway incident scene until law enforcement can assess the evidentiary value?

The most comprehensive approach to preserving a roadway incident scene involves taking multiple proactive steps to ensure that vital evidence remains intact and accessible for law enforcement. This means not only documenting the scene but also taking measures to manage the area effectively until authorities can arrive.

Keeping the scene clear of all vehicles is crucial as it prevents any possible contamination or alteration of the evidence. Documenting the scene with photographs is essential because it creates a visual record of the arrangement of vehicles, any skid marks, debris, and other key details that could be vital in an investigation. Alongside these actions, it is important to manage the scene to ensure safety for all involved and minimize further incidents.

Waiting for law enforcement to arrive without taking any action is not advisable, as it can lead to a loss of critical evidence or allow the scene to become chaotic. Therefore, taking a comprehensive approach as suggested by the correct answer not only preserves evidentiary value but also maintains the safety and integrity of the roadway incident scene until law enforcement can take over.
