Identification cards — Texas Permit Test
Identification cards on the Texas permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A Texas identification card may be issued to a person of any age, and anyone under 21 has UNDER 21 printed on it.
An ID card is for people who do not drive, so no age bar makes sense. The under-21 marking does the same job it does on a license.
ID cards can be issued to any person of any age. Anyone under the age of 21 will have “Under 21” printed on the card
An identification card is printed in a vertical format for a person under 21 and horizontally for a person 21 or older.
The card has to be read across a counter in a second. Turning it on its side says the age before anyone reads a date.
ID cards are displayed in a vertical format for individuals who are younger than 21 years of age and are horizontal for individuals who are 21 years of age and older
State law requires the department to print a directive-to-physician line and an emergency contact number line on the back of the card.
In a crash the card may be the only thing that can speak for the person holding it. The printed lines are there so somebody can be called.
On the reverse side of the card, state law requires DPS to print the statement “Directive to physician has been filed at telephone
The department does not print medical information on a license or identification card, so a holder writes an allergy on the back in permanent ink themselves.
The state will not carry a medical record it cannot keep current. Writing it by hand keeps it with the person and up to them.
To add medical information to the back of your driver license or ID card, use a permanent ink pen and write the name of medication that may cause an allergic reaction
On the test
Who may be issued a Texas identification card?
A person of any age, young or old. An ID card is for people who do not drive, so no age bar makes sense. The under-21 marking does the same job it does on a license. Texas Driver Handbook, p.5: “ID cards can be issued to any person of any age. Anyone under the age of 21 will have “Under 21” printed on the card”
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.

- 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.
