Signaling — Texas Permit Test
Signaling on the Texas permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver must signal continuously for at least 100 feet before turning or stopping.
A signal flicked on at the corner tells the driver behind nothing they can use. A hundred feet is enough distance to react in.
Signal continuously for at least 100 feet before turning or stopping, and be sure to turn off your signal lights once your turn is complete
A driver must turn the signal off once the turn is complete, because an unintended signal still means turn to other drivers.
A blinker left running invites the driver waiting at the side road to pull out. They are reading it as a promise.
Your unintended signal still means “turn” to other drivers
A driver must signal before changing lanes, making a turn, pulling away from a parking space parallel to the curb, slowing or stopping, entering or leaving a highway, and pulling over.
Every one of these puts the car somewhere the driver behind is not expecting. The signal is the only warning they get.
Always signal when you are going to: 1. Change lanes 2. Make a turn 3. Pull away from a parking space parallel to the curb
A driver may use turn signal lights or hand and arm signals, and a hand signal is given with the hand and arm well out of the car window.
An arm held inside the window is invisible from behind. The rule is about how far out it goes.
If using hand signals, extend your hand and arm well out of the car window as shown below
Hand and arm signals are usually hard to see during non-daylight hours, so signal lights must be working properly.
An arm out of the window disappears after dark. The lamps are what carry the message at night.
Hand and arm signals are usually difficult to see during non-daylight hours, so it is important to make sure your signal lights are working properly
When signaling a stop, a driver pumps the brakes a few times to attract attention.
A single brake light in heavy traffic is easy to miss. Flashing it is what makes the driver behind look up.

On the test
How far before a turn must a Texas driver signal?
At least 100 feet. A signal flicked on at the corner tells the driver behind nothing they can use. A hundred feet is enough distance to react in. Texas Driver Handbook, p.38: “Signal continuously for at least 100 feet before turning or stopping, and be sure to turn off your signal lights once your turn is complete”
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.
