• Abstract:
  The intent of a move over law is to protect first responders as they respond to an incident. When first responders are positioned near or in active travel lanes, they and their vehicles may be put in harm’s way due to the close proximity of other vehicles. All 50 States have some form of a move over law, whereby approaching users are required to slow down and move over to ensure the safety of first responders. This CDA feature allows emergency response vehicles (ERVs) to broadcast a vehicle-to-everything (V2X) message containing the global positioning system point of the incident, along with a desired speed reduction and desired safety margins for the passing vehicles. Surrounding vehicles would receive and interpret this information to avoid the lane (or space, as shown in figure 1) adjacent to the ERV and reduce their speed when passing.
