MI HB6299

Amends the Highway Advertising Act of 1972 to restrict local governments from adopting sign ordinances based on sign content unless narrowly tailored to achieve a compelling governmental interest.

Declares void any county, city, village, township, or charter township ordinance that restricts, prohibits, or limits signs based on content unless it meets the narrow tailoring and compelling governmental interest standard.

Preserves local authority to regulate sign operation, size, lighting, and spacing through ordinances, but prohibits content-based restrictions that are not narrowly tailored.

Allows existing local ordinances that are more stringent than state law, ordinances predating March 31, 1972 that prohibit signs, and zoning codes designating commercial or industrial areas to remain valid.

Takes effect 90 days after enactment.
