Turns — Massachusetts Permit Test
Turns on the Massachusetts permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Signal your turn at least 100 feet before making it, and at least 500 feet before a turn on a highway.
A hundred feet is about seven car lengths. Signaling as you begin to brake is signaling too late.
Signal your turn at least 100 feet before making the turn. On a highway, signal at least 500 feet before a turn.
It is best to signal before you apply your brakes, so your intentions are known to other drivers.
Brake lights say you are slowing. Only the signal says why, and the driver behind needs the why.
It is best to signal before you apply your brakes, so you make your intentions known to other drivers.
Turn from the lane closest to the lane you want to enter: from the far right lane for a right turn, and from the lane closest to the center for a left turn.
Turning from the wrong lane crosses the path of whoever is in the right one. It is the commonest cause of a turning crash.
For a left turn, turn from the lane closest to the center lane.
Do not swing your vehicle out of your lane when making a turn, or swing wide through the intersection.
Swinging out first is how a truck turns and how a car hits the vehicle beside it. Keep the car centered in the lanes it leaves and enters.
Do not swing your vehicle out of your lane when making a turn or swing wide through the intersection.
Once you have started a turn through an intersection you must follow through, rather than stopping in mid-turn and changing direction.
Everybody around you has already committed to what you started. Changing your mind mid-turn is a decision they cannot see.
Once you have started a turn through an intersection, you must follow through. Do not stop in mid-turn and change direction.
Before a turn, check your mirrors for traffic behind you and check the blind spot on your turning side.
A bicycle or a motorcycle on the turning side is exactly what the mirror does not show.
Check your mirrors for traffic behind you and check the blind spot on your turning side.
On the test
How far before an ordinary turn must a driver signal?
At least 100 feet. A hundred feet is about seven car lengths. Signaling as you begin to brake is signaling too late. Massachusetts Driver's Manual, p.97: “Signal your turn at least 100 feet before making the turn. On a highway, signal at least 500 feet before a turn.”
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.
