Warning signs hazards — Texas Permit Test

Warning signs hazards on the Texas permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

This sign means a driver should slow down on a wet road and not suddenly turn, speed up, or stop.

A road that grips in the dry can let go entirely in the wet. Every sudden movement is what breaks the grip.

Slow down on wet road. Do not suddenly turn, speed up, or stop

Texas Driver Handbook, p.27

This sign means there is a sudden high place in the road ahead, so a driver should slow down to avoid losing control or an uncomfortable jolt.

Hitting it at speed lifts the wheels off the road for a moment. What comes after that is not steering.

There is a sudden high place in the road ahead. Slow down in order to avoid losing control of your vehicle or an uncomfortable jolt

Texas Driver Handbook, p.29

This sign means a driver is approaching a downgrade and may need to use a lower gear to slow the vehicle.

Riding the brakes down a long hill boils them until they stop working. A lower gear does the slowing instead.

You are approaching a downgrade; all drivers approach with caution. It may be necessary to use a lower gear to slow your vehicle

Texas Driver Handbook, p.29

This sign means a driver should slow down and stay alert, and be prepared to stop if animals appear.

Animals move in groups and at dusk. The one you see crossing is rarely the only one there.

Slow down and stay alert. Be prepared to stop if animals appear

Texas Driver Handbook, p.29

On the test

What does this sign tell a driver to avoid doing?

Turning, speeding up or stopping suddenly. A road that grips in the dry can let go entirely in the wet. Every sudden movement is what breaks the grip. Texas Driver Handbook, p.27: “Slow down on wet road. Do not suddenly turn, speed up, or stop”

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

  • One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
  • Free to start: a 10-question test and the first section of cards. No sign-up and no account.
  • 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.
