The bill amends the Michigan Vehicle Code by updating definitions and regulations related to authorized emergency vehicles and the responsibilities of drivers when approaching such vehicles. It introduces new definitions for "road service vehicle" and "road work vehicle," while removing the previous definition of "road service vehicle." The bill also expands the types of vehicles classified as authorized emergency vehicles and specifies the requirements for drivers when approaching stationary emergency vehicles, including the need to reduce speed and yield the right-of-way.

Additionally, the bill modifies penalties for violations related to the approach of stationary emergency vehicles, changing the consequences from misdemeanors to civil infractions with specified fines. For example, a violation when the stationary vehicle has emergency personnel present incurs a higher fine. The bill also repeals a section of the Vehicle Code and stipulates that its enactment is contingent upon the passage of related legislation. Overall, the bill aims to enhance safety for emergency responders and clarify the legal framework surrounding vehicle operation in emergency situations.
