If you are in an intersection and see an emergency vehicle, stop immediately and give them the right-of-way.
true or false?

False

In highway or any intersection, stopping the vehicle might cause crash as vehicles coming behind the first vehicle might hit other vehicle sin front when stooped abruptly.

In case of an emergency vehicle, there will be a traffic sign showing the direction from where the vehicle is approaching. Thus stopping the vehicle at once is not advisable, it may cause accidents.
