The Vehicular Manslaughter medal resembles a wheel on top a five pointed bronze star in Halo 3 & Halo 3: ODST, or a yellow road sign of a black stick figure split in half with entrails and green blood pouring out on top of a five pointed bronze star; it is awarded to individuals after killing 10 opponents without dying using a drivable vehicle on multiplayer matchmaking, in Firefight, and in Campaign in Halo: Reach. The Vehicular Manslaughter medal is the last of the vehicle spree medals in Halo 3 & Halo 3: ODST, and the seconds of the vehicle spree medals in Halo: Reach. This medal can be awarded on any gametype containing a vehicle.
- The easiest playlist to earn the Vehicular Manslaughter medal is Big Team Battle. This is due to the maps containing a large number players and vehicles, and being large enough to avoid power weapons. Players should try to obtain an agile vehicle such as the Ghost or the Revenant and use the Covenant vehicle boost ability to run players over whilst maintaining an avoidance to danger.
