Final answer:
Motor vehicles must not impede traffic in the left lane, and after a collision, vehicles need to be moved unless they're disabled or there's an injury.
Step-by-step explanation:
In traffic laws, motor vehicles are not allowed to continuously impede traffic by operating in the left lane of a multi-lane roadway. After a collision, the driver should move their vehicle off the roadway unless it is disabled or there is an injury.
When it comes to emergency or authorized vehicles, drivers are required to move to the lane farthest from the stopped authorized vehicle if possible, or slow down if not. Authorized vehicles are identified as having flashing, revolving, or rotating lights that are blue, red, amber, white, or green, and they may be emergency response, ADOT, contractor, utility company, or towing vehicles.Authorized vehicles include those with specific flashing lights and belonging to certain services; drivers must change lanes or slow down when approaching them.Following these rules, including the proper response to emergency vehicles and obeying traffic signals, ensures road safety and compliance with the law.
