Left turn — District of Columbia Permit Test
Left turn on the District of Columbia permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
For a left turn, get into the left lane on your side of the highway well ahead of the turn, and turn into the left lane going your way.
Ending in the left lane keeps you clear of cars turning right from the other direction into the same street.
Get into the left lane on your side of the highway well ahead of the turn
When turning left, do not cut the corner or turn so wide that you get into the right lane going your way.
Cutting the corner puts you in the path of cars waiting at the far side, and a wide turn sweeps across the lane meant for right-turners.

When turning left, yield to oncoming traffic including bicycles, and do not block the intersection while waiting for oncoming traffic to clear.
A car stopped in the middle of the intersection holds up cross traffic when the light changes and invites a side crash.

On the test
Into which lane should a left turn bring you?
The left lane going your way. Ending in the left lane keeps you clear of cars turning right from the other direction into the same street. DC Driver Manual, p.73: “Get into the left lane on your side of the highway well ahead of the 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.
