What kind of vehicles should drivers be particularly cautious around due to their audible/visual signals?

Drivers should be particularly cautious around emergency vehicles due to their audible (siren) and visual (flashing lights) signals. These signals are designed to alert other drivers and pedestrians of the vehicle's presence and the need to yield or clear the way for urgent responses, such as police cars, ambulances, and fire trucks. Emergency vehicles often operate under high-pressure situations where time is critical, so it is essential for other road users to be aware of their presence and react appropriately. By understanding that these vehicles have the right of way and that they may make abrupt maneuvers to navigate traffic, drivers can contribute to safer road conditions when sharing the road with such vehicles.
