This bill amends various sections of the Oklahoma Statutes related to motor vehicle lighting requirements. Key changes include the requirement for all vehicles to display lamps and illuminating devices at all times, regardless of atmospheric conditions, as specified in Section 12-201. The bill updates statutory language and references, ensuring that the United States Department of Transportation specifications for lighting equipment are adopted by the state. Additionally, it clarifies that the visibility requirements for lamps and devices apply at all times, not just during specific times of day or under certain conditions.

The bill also introduces specific provisions for bicycles, mandating that they be equipped with front and rear lamps visible from a distance of at least one thousand feet at all times, with exceptions for bicycles operated on streets or highways with a speed limit of twenty-five miles per hour or less. Other amendments include the requirement for animal-drawn vehicles to have proper lighting and reflectors visible from a distance of one thousand feet. The act is set to take effect on November 1, 2026.
