Opticom emergency vehicle pre-emption (EVP) technology works alongside intersection controllers to help ensure emergency vehicles can move through intersections quickly and safely.

When an emergency vehicle needs to navigate an intersection, the Opticom EVP system onboard the emergency vehicle sends a request to the intersection’s controller ahead of its arrival. If the request is granted, the light turns green and the vehicle gets a clear path through the intersection.
