What type of vehicles are typically used in block positioning?

Block positioning is a traffic incident management technique aimed at safeguarding responders and the incident scene from oncoming traffic. The primary vehicles used in this method are larger emergency vehicles, such as fire apparatus. These vehicles are strategically placed to create a physical barrier between the traffic and the accident scene, which not only helps protect the responders working on the incident but also prevents secondary crashes.

The height and size of larger emergency vehicles provide a more substantial and visible obstruction against incoming traffic. Their substantial mass and visibility help alert drivers to the presence of an incident ahead, allowing them to slow down and navigate safely. This approach enhances the safety of all personnel on the scene, effectively reducing risks involved in handling emergencies on active roadways.

Other types of vehicles, such as standard passenger vehicles, motorcycles, bicycles, and small utility vehicles, do not offer the same level of protection or visibility as larger emergency vehicles. While they may be effective for other purposes, they are not suitable for block positioning due to their size and weight, which do not provide adequate protection from traffic.
