SB 840

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.
