Stationary emergency vehicles — Massachusetts Permit Test
Stationary 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

You must slow down and stay alert when you see an “emergency response vehicle” stopped ahead of you with its emergency lights flashing.
Always be ready to stop if necessary when passing a stationary emergency vehicle, and dim your high beams at night.

On the test
What must a driver do when an emergency response vehicle is stopped ahead with lights flashing?
Slow down and stay alert. Somebody is working in the lane beside it, and they have their back to the traffic. Massachusetts Driver's Manual, p.120: “You must slow down and stay alert when you see an “emergency response vehicle” stopped ahead of you with its emergency lights flashing.”
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.
