Final answer:
Ambulances do not use police escorts as they are equipped with lights and sirens to navigate through traffic and ensure a clear path. The lights and sirens alert other drivers on the road and help ambulances reach the destination more efficiently.
Step-by-step explanation:
Ambulances do not typically use police escorts because they are equipped with lights and sirens to quickly navigate through traffic and for the safety of the patients inside. When an ambulance responds to an emergency, it uses its lights and sirens to alert other drivers on the road and ensure a clear path. Police escorts are not necessary because an ambulance can maneuver through traffic and reach the destination more efficiently with the help of its emergency lights and sirens.
