1. A vehicle guidance device comprising:
at least one light reflector including:
a retroreflector configured to reflect laser light for distance measurement emitted from a vehicle for autonomous driving; and
a reflection setter configured to set either a first state in which the laser light is retroreflected from the retroreflector toward the vehicle, or a second state in which the laser light is not retroreflected from the retroreflector toward the vehicle; and
a controller configured to cause the reflection setter to set the first state by setting a target position of the vehicle associated with the light reflector and causes the reflection setter to set the second state after the vehicle arrives at the target position.
