Relating to: repealing unconstitutional provisions related to operating while intoxicated.

AB 856 repeals and amends specific sections of state law related to operating while intoxicated (OWI) that were deemed unconstitutional by the U.S. Supreme Court. The bill primarily affects drivers of all-terrain vehicles (ATVs), utility terrain vehicles, and motorboats who face penalties for OWI or refusal to submit to chemical tests. Key changes include adjusting penalty tiers for repeat offenses (e.g., fines of $300-$1,100 for one prior conviction, up to $2,000 for four or more), clarifying when refusal constitutes a violation, and adding provisions for "additional chemical tests" for ATV/boat operators involved in accidents. The bill also revises procedures for law enforcement officers requesting tests and providing required information. These changes aim to align the statutes with constitutional standards while maintaining enforcement mechanisms for impaired operation.
