Short answer: Texas driver's licenses can carry restriction codes — letters (and some letter-number combinations) printed on the license under authority of Texas Transportation Code § 521.221 — requiring things like corrective lenses, daytime-only driving, or other conditions. The most common violation by far is a Code A citation for driving without the required corrective lenses. A single violation is a misdemeanor with a fine of up to $200. It's the second conviction that becomes serious: two or more restriction-violation convictions can trigger a Department of Public Safety suspension of your license for 90 days up to a full year.
Under Texas Transportation Code § 521.221, the Department of Public Safety may place a restriction on a driver's license "for good cause" to help ensure the license holder can safely operate a motor vehicle. A restriction can relate to:
These restrictions are printed directly on the license as a code, and officers are trained to check for them during a traffic stop.
By far, the most common restriction violation is a Code A citation — a license marked "with corrective lenses" where the driver is stopped not wearing glasses or contacts. This one comes up constantly: a driver gets a license with a vision restriction, later feels their eyesight is fine, stops wearing their glasses, and gets pulled over for an unrelated reason (or even specifically because an officer notices no glasses) — resulting in a restriction violation citation in addition to, or instead of, whatever prompted the stop.
DPS publishes the following standard restriction codes that may appear on a Texas driver's license:
| Code | Meaning |
|---|---|
| A | With corrective lenses |
| B | A licensed driver 21 or older must be in the front seat |
| C | Daytime driving only |
| D | Speed not to exceed 45 mph |
| E | No manual transmission-equipped commercial motor vehicle |
| F | Must hold a valid learner license until a stated date |
| G | Transportation Code § 545.424 applies until a stated date |
| H | Vehicle not to exceed 26,000 lbs. GVWR |
| I | Motorcycle not to exceed 250cc |
| J | Licensed motorcycle operator 21 or older must be in sight |
| K | Intrastate driving only |
| L | No air-brake-equipped commercial motor vehicle |
| S | Outside rearview mirror or hearing aid required |
| T | Automatic transmission only |
| U | Applicable prosthetic devices required |
| V | Medical variance documents required |
| W | Power steering required |
| Y | Valid Texas vision or limb waiver required |
Several additional codes (M, N, O, P, Q, R, X, Z, and the numbered "P1"–"P40" series) apply mainly to commercial driver's licenses and specific commercial vehicle classes. Whatever code appears on your license, the same basic rule applies: driving in a way that violates that printed restriction can result in a citation.

Under Texas Transportation Code § 521.221(c), operating a motor vehicle in violation of a restriction printed on your license is a misdemeanor. Because this specific offense doesn't list its own fine amount, it falls under the Transportation Code's general penalty provision, § 521.461, which sets a fine of up to $200. On its own, a single restriction-violation citation is a fine-only matter — the real risk comes from accumulating more than one.
Yes, in specific circumstances. Under § 521.221(d), a court may dismiss the charge if all of the following are true:
The key detail many people miss: simply having had the vision-correcting surgery, or switching to contacts, isn't enough by itself. The restriction has to actually be removed from your license record with DPS before your first court date for the dismissal option under this section to apply.
Under § 521.221(e), DPS is required to remove a corrective-lens restriction and mail a new license without it if the license holder submits:
DPS maintains a process to submit this documentation electronically or by mail, separate from visiting a driver license office in person.
Yes — and this is where a single Code A ticket can turn into a much bigger problem. According to the Texas Department of Public Safety's own driver license enforcement actions reference, a person who receives two or more convictions for violating a license restriction is subject to a departmental suspension under Transportation Code § 521.292(a)(6):
In short: one restriction citation is a fine. Two convictions can cost you your license for months. This is functionally the same structure as the two-conviction rule for no-insurance citations — a pattern Texas uses in several places in the Transportation Code to escalate consequences for repeat violations.

Code A means the license holder is required to wear corrective lenses (glasses or contacts) while driving. It's the single most common restriction code violation.
Not by itself. You also need DPS to actually remove the restriction from your license record before your first court appearance, and you'll pay a reimbursement fee of up to $10.
A single conviction is a fine-only misdemeanor (up to $200). The real risk is a second conviction, which can trigger a 90-day to one-year license suspension.
Many, covering everything from daytime-only driving and speed limits to required mechanical devices and vehicle types — see the full table above.
A restriction violation ticket is easy to underestimate — especially if it's not your first one. If you've been cited for violating a license restriction in Houston or anywhere in Harris County, find out what's actually at stake, and whether dismissal is realistic in your situation, before your court date.
