Shared center turn lane — Louisiana Permit Test
Shared center turn lane on the Louisiana permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When using a shared center left turn lane, watch for vehicles pulling out of entrances and side streets.
Cars leaving driveways and side streets may pull into the same center lane you are in.
Watch for vehicles pulling out of entrances and side streets and do not use a shared left turn lane for anything but turning left.
Do not move into a shared center turn lane too soon; the longer you stay, the more likely you meet someone coming the other way.
Both directions share that lane. Less time in it means less chance of meeting an oncoming turner.
Do not move into the lane too soon.
The solid yellow line beside a shared center left turn lane means you cannot use the center lane for passing.
Passing in the center lane would put you in the path of cars waiting there to turn.
The solid yellow centerline means you cannot use the center lane for passing.
On the test
While you are in a shared center left turn lane, what should you watch for?
Cars pulling out of side streets. Cars leaving driveways and side streets may pull into the same center lane you are in. Class D & E Driver's Guide, p.91: “Watch for vehicles pulling out of entrances and side streets and do not use a shared left turn lane for anything but turning left.”
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.
