10	Safety Applications Vehicle to Vehicle (V2V) Forward Collision Warning Lane Change Assist Intersection Movement Assist Electronic Emergency Brake Light (EEBL) Vehicle to Infrastructure (V2I) Curve Overspeed Warning (spline, speed distribution, or min curve speed methods) In-vehicle signage applications (speed limit, construction zone, or other)
11	Forward Collision Warning Helps drivers avoid or mitigate rear-end vehicle collisions in the forward path of travel Remote vehicle (RV) must be ahead of host vehicle (HV) HV above minimum speed threshold Two threat levels when range less than threshold Warning suppressed if HV brake applied
12	Blind Spot Warning/Lane Change Warning Helps drivers avoid or mitigate collisions with vehicles in or approaching blind spot RV must be behind left or behind right to be in blind spot zone HV and RV must be above minimum speed threshold Two threat levels depending on use of turn signal and RV in or approaching applicable blind spot
13	Emergency Electronic Brake Lights Helps drivers avoid or mitigate rear-end collisions with braking vehicles in the forward path of travel RV broadcasts hard brake event and must be ahead, ahead left, or ahead right of HV to be potential threat HV must be above minimum speed threshold Two threat levels depending on range, RV deceleration, and zone Warning suppressed if sufficient HV brake applied
14	Intersection Movement Assist Helps drivers avoid or mitigate vehicle collisions at stop sign controlled and uncontrolled intersections Vehicles must be intersecting left or right Vehicle 1 braking or creeping forward Two threat levels depending on scenario Warning suppressed if speeds or paths altered enough to avoid collision
