Overview of flashing light permits
What’s a flashing light permit?
Certain emergency or maintenance vehicles may be allowed to display lights other than most standard motor vehicle lights, known as flashing or siren lights (or safety lights/emergency lights). These lights and sirens alert other motorists of an emergency or maintenance situation.
The display of flashing lights on such emergency or maintenance vehicles requires a written permit from the DMV as described in CGS Section 14-96q.
