If the bike has a license, then it is an official vehicle and you need to ride it on the road and stop for the ambulance and get on the shoulder of the road.
Friction is what ultimately stops your bike
You push the brake.
It is impossible to say what the individual driver may do. By law, they must stop. Most emergency personnel would stop.
After an emergency stop on a bike, you need to start on a low note and low speed. You will keep accelerating as you gain momentum.
As an EMT, I work on the ambulance a lot and I've seen many ways people try to get out of the way of an ambulance. On ANY road, when an emergency vehicle is coming, SLOW DOWN, or STOP and pull to the RIGHT. That is the correct way to yield right of way to an ambulance. This will help ambulance crews AA whole lot.
