SB840,,33Analysis by the Legislative Reference Bureau This bill authorizes snow removal vehicles to be equipped with lamps or other transmitters to communicate with traffic control signals equipped with traffic control signal priority devices. These devices allow the operator of the vehicle to request that a green signal be provided or maintained to allow the vehicle to proceed through the intersection.
Under current law, authorized emergency vehicles may be equipped with lamps or other transmitters to communicate with traffic control signals equipped with emergency preemption devices, which allow the operator of the vehicle to alter the normal traffic control sequence to provide or maintain a green signal to allow the vehicle to proceed through the intersection.
The bill provides that the authority responsible for maintenance of a traffic control signal may establish procedures for resolving conflicts between multiple requests for signal preemption or priority at a traffic signal, except that a signal preemption request from an emergency vehicle must be given priority over any signal priority request.
For further information see the state and local fiscal estimate, which will be printed as an appendix to this bill.
