Buses trolleys and slow vehicles — Massachusetts Permit Test
Buses trolleys and slow vehicles on the Massachusetts permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You must not drive closer than eight feet to a trolley passenger step when the trolley is letting passengers on or off.
Passengers step straight off the trolley into the road. Eight feet is the room they need to be there.
You must not drive closer than eight feet of a trolley passenger step when the trolley is letting passengers on or off.
Look for oncoming trolleys before crossing any tracks, and do not turn in front of an approaching trolley.
A trolley cannot swerve. Its path is the tracks, and nothing you do changes where it is going.
Remember, a trolley’s path is limited to the tracks. A trolley driver cannot swerve to avoid you.
Be courteous and allow signaling buses to pull away from bus stops.
A bus rejoining traffic is the vehicle least able to find a gap, and it stops again a few hundred feet later anyway.
Be courteous and allow signaling buses to pull away from bus stops.
Most farm vehicles, construction rigs, and other slow-moving vehicles carry orange warning signs on the back, and you should reduce speed and use caution.
The orange triangle means the vehicle may be doing fifteen miles an hour. Closing on it at fifty happens faster than it looks.
Most farm vehicles, construction rigs, and other slow-moving vehicles have orange warning signs attached to the back.
Treat slow-moving vehicles like bicyclists and pedestrians, and leave plenty of space around them if you plan to pass.
They cannot get out of your way and they may turn into a field without much warning.
Treat them similar to bicyclists and pedestrians. Leave plenty of space around the vehicle if you plan to pass.
On the test
How close may a vehicle come to a trolley passenger step while passengers board?
No closer than eight feet. Passengers step straight off the trolley into the road. Eight feet is the room they need to be there. Massachusetts Driver's Manual, p.107: “You must not drive closer than eight feet of a trolley passenger step when the trolley is letting passengers on or off.”
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.
