School bus stop arm violation enforcement.

Provides that a registered owner of a motor vehicle commits an infraction if the owner's vehicle is used to violate the school bus stop arm law. Provides a defense for a registered owner who provides certain information to law enforcement and fully cooperates with law enforcement, if: (1) the vehicle was stolen; (2) the registered owner routinely engages in the business of renting the vehicle; (3) the registered owner provided the vehicle for the use of an employee; or (4) the registered owner provides documentary evidence that the owner was out of state at the time the violation was committed. Specifies that: (1) the bureau of motor vehicles may not assess points for the infraction; and (2) an adjudication for the infraction does not create a presumption of liability in a civil action.
