Moving emergency vehicles — Massachusetts Permit Test
Moving emergency vehicles on the Massachusetts permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Always yield to fire engines, ambulances, police cars, and other emergency vehicles using a siren or flashing lights.
The siren is asking for road that you are currently occupying. Everything else can wait.
Always yield the right-of-way to fire engines, ambulances, police cars, and other emergency vehicles that are using a siren and/or emergency flashing lights.
If an emergency vehicle is coming from any direction, pull as close as possible to the right side of the road and stop, because slowly rolling is not acceptable.
A rolling car is still moving into space the ambulance needs. Stopped is the only state that helps.
If an emergency vehicle is coming from any direction, you must pull as close as possible to the right side of the road. Stop until the vehicle has passed. Slowly rolling is not acceptable.
Never stop in the middle of an intersection for an emergency vehicle; drive through and pull over as soon as it is safe.
A car stopped in the box blocks every direction, including the one the ambulance is taking.
NEVER stop in the middle of an intersection. Drive through the intersection and pull over as soon as it is safe.
Do not pull to the left or slam on your brakes for an emergency vehicle; check your mirrors, use your right turn signal, and find a safe place to pull over.
The driver behind is watching for the same siren. A sudden stop or a swerve left is what they cannot predict.
You should not pull your vehicle to the left or slam on your brakes. Do not stop suddenly.
It is illegal to follow closer than 300 feet behind an emergency vehicle responding to an alarm.
Following one to get through traffic puts you inside the space it may need to stop or turn.
It is illegal to follow closer than 300 feet behind an emergency vehicle responding to an alarm.
After an emergency vehicle has passed, use your left turn signal, make sure the lane is clear, and check that no other emergency vehicles are approaching.
They often travel in groups. Pulling back out in front of the second one is the ordinary mistake.
Be sure there are no other emergency vehicles approaching.
On the test
Who must a driver yield to when a siren or flashing lights approach?
Fire engines, ambulances, police cars, and other emergency vehicles. The siren is asking for road that you are currently occupying. Everything else can wait. Massachusetts Driver's Manual, p.120: “Always yield the right-of-way to fire engines, ambulances, police cars, and other emergency vehicles that are using a siren and/or emergency flashing lights.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
