Speed limit signs — Texas Permit Test

Speed limit signs on the Texas permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.

The rules

This sign tells a driver the maximum speed they are permitted to travel, and it also shows the maximum speeds permitted for day time and nighttime.

It is a limit, not a target, and it assumes everything about the road is normal. In rain it is already too fast.

This sign gives the highest speed at which a driver can safely travel around the curve ahead.

It is not the posted limit and it is not advice about traffic. It is the speed the bend itself will take.

On the test

What does this sign tell a driver?

The maximum speed they may travel. It is a limit, not a target, and it assumes everything about the road is normal. In rain it is already too fast. Texas Driver Handbook, p.30: “This sign tells you the maximum speed (in mph) you are permitted to travel”

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.
