A bill for an act relating to operators of motor vehicles approaching certain slow-moving authorized emergency vehicles, and making penalties applicable.

HF 542 requires drivers to approach slow-moving authorized emergency vehicles (operating at 15 mph or less) with caution, mirroring existing rules for stationary emergency vehicles. Drivers must change lanes if safe, or reduce speed below the limit and be prepared to stop if lane changes aren't possible. The bill defines "slow-moving" as 15 mph or less for emergency vehicles performing official duties. Violations remain a simple misdemeanor with a $135 fine, plus potential higher fines and license suspensions if accidents cause injury or death. This applies only to emergency vehicles, not other slow-moving vehicles like construction or utility vehicles.
