Traffic Magnet is a powerup used to slow down the leading player in a race. When a Traffic Magnet is activated, traffic cars will attempt to collide with the race leader. If the race leader crashes into a traffic car the race leader will lose time, allowing the other players behind to catch up.
This power-up can be blocked if the leading player triggers a Shield to protect him or herself. Juggernaut may also help the leader get through any collisions without losing much time.
