In Halo 2, the traffic cones were a triangle with an exclamation point on them. There was a Scarab gun in Halo 2 that floated over a traffic cone on a ridiculously high bridge.
In Halo 3, it is on many Human based maps, such as The Pit and Foundry (Heroic Map pack). These cones are usually found around Fusion coils. If the Fusion coils are shot, or a grenade is thrown at them or they are stuck with a plasma grenade/spike grenade, the traffic cone will shoot across the map at great speed. It is possible to be splattered by a traffic cone. They also appear several times in Campaign.
- The first person to get killed by a traffic cone in Halo 3 received the Recon Armor. (Please note that Bungie employees did not appreciate getting constant emails about being cone-splattered.).
- If you get a splatter kill with an Elephant or Hornet and look on Bungie.net, it will say you were killed by a traffic cone.
- If you get a kill/killed by a traffic cone, on your Bungie.net profile it will say under classified: "I'm calling my lawyer!"
