Passing and turning signs — Texas Permit Test

Passing and turning signs 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 do not pass other vehicles.

It is posted where the road ahead hides what is coming. Passing here is the crash the sign exists to prevent.

Do not pass other vehicles

Texas Driver Handbook, p.30

This sign marks a zone where the distance a driver can see ahead is so limited that passing another vehicle is hazardous and may not be done.

The zone is measured by sight distance, not by how the road feels. What you cannot see is the oncoming car.

Texas Driver Handbook, p.30

Turning left at an intersection where this sign is posted is prohibited.

The turn would cross traffic that has nowhere to go. Texas closes the movement rather than timing it.

Texas Driver Handbook, p.30

Making a U-turn at an intersection where this sign is posted is prohibited.

A U-turn crosses every lane on the road at once, slowly. Where the sightlines are poor, Texas takes the option away.

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.
