Volunteer first responders warning lights on personal vehicles when responding to a call specification provision

This bill allows volunteer firefighters, emergency medical first responders, and ambulance crew members to use red or red-and-white flashing warning lights on their personal vehicles while responding to emergency calls. It requires permits from the public safety commissioner, limits light size to under three inches, and mandates lights only be activated during actual emergency responses. The law amends existing statutes to explicitly permit these lights on personal vehicles for volunteer responders, specifying they must be deactivated when not responding to calls. It directly affects volunteer emergency personnel operating personal vehicles during emergency duties in Minnesota.
