Relates to the expiration of vehicle registrations

This bill changes when vehicle registrations expire, setting the expiration date to the last day of the month the registration is valid. It specifically states that registrations for most vehicles (excluding taxis or buses) will expire on the last day of the month, unless that date falls on a weekend or state holiday - then they remain valid until midnight of the next business day. Vehicle owners will need to renew registrations by the month's end, with the holiday exception preventing last-minute issues. The bill also adjusts renewal rules for cases where expired registration documents weren't surrendered before expiration.
