Texas Permit Test Cheat Sheet: Key Numbers to Memorize

A useful Texas permit test cheat sheet pairs each number with the situation it applies to. For example, the Texas Driver Handbook sets a 70% knowledge-test passing standard, but speed and parking questions need more than a percentage to answer correctly. Use this sheet to review before testing; it is a study aid, not something to use during an exam.

Which speed limits should you memorize for Texas?

Learn the default road categories, then check whether a posted limit or hazard changes the answer. The Texas speed statute requires reasonable and prudent speed for the conditions. A default number is not permission to ignore a sign or drive too fast for poor visibility.

These ordinary-car defaults do not cover every vehicle class or locally altered limit. Read the sign, road category, and conditions together. Our Texas speed limits guide explains why “Texas allows 85” is not a complete answer to a question about an ordinary road.

What parking distances belong on your review sheet?

The handbook parking chapter distinguishes places where you must not stop or stand from places where parking is restricted. Memorize both the distance and the object it belongs to. Do not carry a number from a hydrant question into a crosswalk question.

These are not the complete parking rules. Signs, driveways, accessible spaces, and other locations add restrictions. Draw a simple intersection and label the distances so you can remember which boundary a question refers to. Read the full handbook passage when you are unsure whether a rule concerns stopping, standing, or parking.

What following-distance and signaling numbers matter?

The DPS drive-test guide recommends the two-second rule for following space, with a larger gap when weather, road, or traffic conditions are poor. It also tells drivers to signal 100 feet before a turn or lane-change maneuver. Increase following space as conditions require.

Try counting from a fixed roadside point when a vehicle ahead passes it. If road conditions worsen, give yourself more room to respond. During supervised practice, ask your accompanying driver to help you notice when a gap is shrinking instead of waiting until you have to brake sharply.

Which alcohol and learner-license numbers should you know?

Texas uses a 0.08% intoxication threshold, but impairment is illegal below that level; drivers under 21 may not drive with any detectable alcohol. Do not memorize “under 0.08 is safe.” The relevant decision is to avoid driving after drinking, not calculate how close you can get to a threshold.

For teen licensing, remember 15 for learner eligibility and a supervisor age 21 or older in the front seat. Keep those age requirements separate from provisional milestones. Our Texas GDL guide covers practice hours and later driving restrictions.

Can you match a number to the right road type?

Try this app question without looking back at the table, then explain why its road category matters.

If you remembered only the number but not “unless otherwise posted,” reread the question. Our Texas written test guide helps you connect details like that with the exam’s broader topics.

Key takeaways

• Pair each number with its road, location, age group, and exceptions.
• Posted limits and unsafe conditions can change a speed answer.
• Review the handbook passage when similar parking distances blur together.
