Warning signs ahead — Texas Permit Test
Warning signs ahead on the Texas permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
This sign warns of a traffic control signal ahead.
A signal hidden behind a rise or a bend gives no time to stop. The sign is the warning that one is coming.
Warns of a traffic control signal ahead
This sign means a driver should be prepared for a stop sign ahead.
A stop sign that appears late leaves a driver braking hard into an intersection. This one buys the distance back.
Be prepared for a stop sign ahead
This sign means a cross road is ahead, so a driver should slow down and look carefully in all directions for cross traffic.
Traffic can arrive from either side at once here. Looking one way and going is how people are hit.
Cross road ahead; slow down and watch for cross traffic. Look carefully in all directions for traffic
This sign means other traffic lanes come together with the lane a driver is in, so they should watch for traffic from that direction.
Two streams of traffic are about to become one. Somebody has to make room and it is easier if both expect it.
You are approaching a point where other traffic lanes come together with the one you are in. Watch for traffic from that direction
This sign means the lane ends ahead, and a driver in the right lane should merge into the left.
The lane simply runs out, usually at speed. Merging early is easier than merging at the last cone.
The lane ends ahead. If you are driving in the right lane, you should merge into the left

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.
