HF3694

Purpose

• Update state transportation law to allow tow trucks to display portable variable message signs (VMS) during emergency work and to set lighting and visibility requirements for tow trucks.

Main Provisions

• Lighting requirements for tow trucks:
  • Tow trucks must have flashing or intermittent red and amber lights.
  • Lights must be placed on the dome of the vehicle at the highest practicable point and be visible from 500 feet.
  • The red light may be displayed only when the tow truck is engaged in emergency service on or near the traveled portion of a highway.
  • The amber light may be displayed when the tow truck is moving a disabled vehicle.
  • Lights must be of a type approved by the commissioner of public safety.
• Portable variable message sign (VMS):
  • A tow truck may display a portable VMS mounted on the truck while performing emergency service on or near the traveled portion of a highway.
  • The portable VMS must conform to the standards established in the Minnesota Manual on Uniform Traffic Control Devices (MUTCD).

Significant Changes to Existing Law

• Adds explicit authorization for tow trucks to carry and display portable VMS during emergency operations near highways.
• Establishes specific lighting requirements (red for emergency service; amber for moving a disabled vehicle) and visibility criteria (visible from 500 feet) and places for mounting (on the dome, at the highest practicable point).
• Requires lights and VMS to meet standards set by the commissioner of public safety and the Minnesota MUTCD.

Practical Effect

• Tow trucks engaged in roadside emergency work can use digital message signs to warn or guide traffic, improving safety for workers and drivers.
• Clear, standardized lighting and display requirements help ensure visibility and consistency across tow operations.
