What the law says
Contrary to widely repeated advice, no cover is required in this state. Mounting a light bar is legal everywhere; what states regulate is using it on public roads, and the usual constraint is a mounting-height ceiling plus a per-type lamp count — a roof-mounted bar often falls outside the permitted category entirely.
Specific Limits
- Max lamps
- 2 each of spot, fog (12-30 in), auxiliary passing (24-42 in), and auxiliary driving lamps (16-42 in)
