Hand signals — Louisiana Permit Test
Hand signals on the Louisiana permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver's left arm held straight out means a left turn.
Hand signals work when signal lights are broken. Others must read them right away.
Arm straight is for a left turn
A driver's left arm bent upward at the elbow means a right turn.
The driver's right arm cannot reach out the window, so the left arm bent up stands for right.
Arm bent up is for a right turn
A driver's left arm bent downward means slowing or stopping.
Drivers behind you need a clear warning to brake, even if your brake lights are out.
Arm bent downward is for slowing or stopping
On the test
What does a driver's left arm held straight out the window mean?
Left turn. Hand signals work when signal lights are broken. Others must read them right away. Class D & E Driver's Guide, p.93: “Arm straight is for a left 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.
What it costs

- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
