Bill Summary · HB 4301

Summary — HB 4301 (Michigan Vehicle Code amendments)

Status: Passed House (June 4, 2025); referred to Committee on Veterans and Emergency Services. Introduced: March 11, 2025. Sponsor: Rep. Brian BeGole. Tie bar: HB 4302 — neither bill takes effect unless both are enacted.

Purpose

HB 4301 amends the Michigan Vehicle Code (MCL 257.2 and 257.698) to (1) add certain vehicles owned by the Michigan Mutual Aid Box Alarm System (MABAS) to the statutory definition of “authorized emergency vehicle,” and (2) permit those vehicles, when operating as part of an emergency response, to be equipped with specific types and colors of emergency lighting.

Key provisions

  • Definition change (MCL 257.2): Adds an authorized-emergency-vehicle category for vehicles that both:
    • Are owned by the Michigan Mutual Aid Box Alarm System (a “public agency” under the Urban Cooperation Act), and
    • Are operated during an interlocal emergency under an interlocal agreement pursuant to the Urban Cooperation Act.
  • Lighting rules (MCL 257.698): Allows an authorized emergency vehicle owned by MABAS and operated as part of an emergency response to be equipped with flashing, rotating, or oscillating lights in one of these colors: red, white, amber, or green.
  • The bill is tied to HB 4302, which would address driver-training and commercial-license exemption issues for MABAS personnel; both bills must be enacted for either to take effect.

Who is affected

  • MABAS and its member agencies: vehicles owned by MABAS gain explicit emergency-vehicle status when operating under mutual-aid/interlocal emergency agreements.
  • MABAS personnel and participating fire/EMS agencies engaged in interlocal emergency responses.
  • Law enforcement, traffic-safety regulators, and the public insofar as authorized lighting and vehicle privileges are expanded during MABAS responses.

Background & context

  • MABAS is a statewide mutual-aid system that coordinates fire, EMS, technical rescue, hazardous-materials, and other specialized resources among signatory departments.
  • The change mirrors prior legislation introduced in the 2023–24 session (HBs 5341/5342).

Fiscal impact and positions

  • House Fiscal Agency: no apparent direct fiscal impact on state or local government.
  • Support: MABAS representative testified in support. Department of State took a neutral position.

Legislative timeline (selected)

  • Filed: 03/11/2025
  • Introduced/read first: 03/25/2025
  • Reported by committee: 05/20/2025

  • Referred to Committee on Veterans and Emergency Services: 06/10/2025

Note: HB 4302 addresses driver-license testing/endorsement exemptions for MABAS personnel; HB 4301 does not take effect unless HB 4302 is also enacted.
