# Lap Manager

The Lap Manager keeps track of how many laps each vehicle has passed and invokes an event when a vehicle passes the [Finish Line](/arcade-racing-kit/systems/finish-line.md). In order to work properly, it requires a [Finish Line ](/arcade-racing-kit/systems/finish-line.md)to be in the scene.
