Lane use turning — Delaware Permit Test
Lane use turning on the Delaware permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Where no signs or lane markings control turning, turn from the lane closest to the direction you want to go.
A car turning right from the left lane cuts across the car beside it.
Where there are no signs or lane markings to control turning, you should turn from the lane that is closest to the direction you want to go and turn into the lane closest to the one you came from.
Where no signs or lane markings control turning, turn into the lane closest to the one you came from, so you cross the fewest lanes of traffic.
A car swinging into the far lane crosses paths with traffic already in the near one.
Where there are no signs or lane markings to control turning, you should turn from the lane that is closest to the direction you want to go and turn into the lane closest to the one you came from.
On a right turn, avoid swinging wide to the left before making the turn.
The driver behind may think you are turning left and try to pass you on the right.
Right turns – On right turns, avoid swinging wide to the left before making the turn.
On a left turn, avoid cutting the corner so sharply that you run into someone approaching from the left.
A driver who cuts the corner meets the car waiting at the stop line on the street he turns into.
Left turns – When making a left turn, avoid cutting the corner so sharply that you run into someone approaching from the left.
Where signs or lane markings allow two or more turning lanes, stay in your lane during the turn.
Two cars turning side by side collide when one drifts across the line mid-turn.
Multiple lanes turning – If there are signs or lane markings that allow for two or more turning lanes, stay in your lane during the turn.
On the test
With no signs or lane markings, which lane should you turn from?
The lane closest to your turn. A car turning right from the left lane cuts across the car beside it. Delaware Driver Manual, p.87: “Where there are no signs or lane markings to control turning, you should turn from the lane that is closest to the direction you want to go and turn into the lane closest to the one you came from.”
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.
