4A ISS is a restriction code that means you must wear corrective lenses while driving
4A ISS on your driver's license is a restriction placed by your state's Department of Motor Vehicles. It means you are required to wear eyeglasses or contact lenses every time you drive. The "4A" is the restriction code, and "ISS" stands for "Issued" — it indicates the restriction is currently active on your license.
This restriction appears on your license because you did not meet the vision requirements for unrestricted driving when you took your eye exam at the DMV. Most states require drivers to see at least 20/40 in each eye (with or without correction) to drive legally. If your uncorrected vision falls below that standard, the DMV adds this restriction to may support you drive safely.
Driving without your corrective lenses when this restriction is on your license is a violation. If you are pulled over and not wearing glasses or contacts, you can receive a citation. The penalty varies by state but typically includes a fine and points on your driving record.
Key Takeaways
- 4A ISS means you must wear glasses or contact lenses every time you operate a vehicle.
- The restriction is added when your vision without correction does not meet your state's minimum standard for driving.
- Driving without corrective lenses when this restriction is active can result in a traffic citation and fines.
- You can have the restriction removed by passing a new vision test at the DMV that shows you meet the uncorrected vision standard.
- The restriction applies only to driving — it does not affect your ability to obtain or renew your license in other ways.
How the restriction gets placed on your license
When you take your vision test at the DMV, the examiner checks how well you can see both with and without correction. If your uncorrected vision is below the legal minimum — usually 20/40 in at least one eye — the DMV places the 4A ISS restriction on your license. This happens automatically; you do not need to request it.
The restriction is added during the initial license exam or during a renewal if your vision has changed. Some states also add it after a failed vision screening during a traffic stop or after an accident. Once the restriction is on your record, it stays there until you pass a new vision test without it.
What you need to do if you have this restriction
If 4A ISS appears on your license, keep your corrective lenses with you whenever you drive. This means glasses in your car or contact lenses in your eyes before you start the engine. A police officer can cite you for this violation even if your vision is otherwise fine — the issue is not whether you can see, but whether you are following the restriction placed on your license.
Make sure your prescription is current. If your vision has changed since your last eye exam, an outdated prescription means you may not be meeting the restriction requirement. Schedule an eye exam with an optometrist or ophthalmologist to confirm your prescription is still correct.
How to remove the restriction
To have 4A ISS removed from your license, you must pass a new vision test at the DMV that shows your uncorrected vision meets the state's legal standard. This means you need to see at least 20/40 in each eye without glasses or contacts. If your vision has improved — for example, after LASIK surgery or other corrective procedures — you may now pass this test.
Schedule a vision exam at your local DMV. Bring your current license and be prepared to pay a fee, which varies by state. The exam takes only a few minutes. If you pass, the DMV will issue you a new license without the restriction, usually within one to two weeks.
If you have had refractive surgery like LASIK or PRK, wait at least three months after the procedure before taking the vision test. Your eyes need time to stabilize after surgery, and testing too soon may give an inaccurate result.
Other vision-related restrictions you might see
States use different codes for different vision restrictions. You might see 4A ISS (corrective lenses required), 4B (limited to daytime driving only), or 4C (restricted to certain distances or speeds). Some states use different letter codes entirely. Check your state's DMV website to understand what any other restrictions on your license mean.
If you have multiple restrictions, they all explore at the same time. For example, if you have both 4A ISS and 4B, you must wear corrective lenses and can only drive during daylight hours. Each restriction must be followed independently.
What happens if you drive without following the restriction
Driving without your corrective lenses when 4A ISS is on your license is a traffic violation. The specific penalty depends on your state, but typically includes a fine ranging from $50 to $250 and points added to your driving record. Points can increase your insurance rates and may eventually lead to license suspension if you accumulate too many.
If you are involved in an accident while driving without your corrective lenses, your insurance company may deny your claim or reduce the payout. The accident report will show that you violated a license restriction, which can be used against you in a lawsuit. This is why following the restriction matters even if you feel you can see well enough without glasses.
Frequently Asked Questions
Can I drive with contacts instead of glasses if I have 4A ISS?
Yes. The restriction requires corrective lenses, which includes either glasses or contact lenses. You can choose whichever works best for you, as long as you are wearing one of them while driving. Make sure your contact prescription is current and that you can insert and remove them safely before driving.
Does 4A ISS mean I failed my vision test?
Not exactly. It means your uncorrected vision did not meet the legal standard, but your corrected vision (with glasses or contacts) does. You passed the overall vision requirement — the restriction straightforward documents that you need correction to drive safely.
Will 4A ISS affect my insurance rates?
The restriction itself does not automatically raise your rates. However, if you receive a citation for driving without your corrective lenses, that violation will appear on your driving record and your insurance company may increase your rates as a result.
How long does it take to get a new license after passing the vision test?
Most states issue a new license within one to two weeks of passing the vision test. Some DMVs offer expedited service for an additional fee. You can usually drive with your old license until the new one arrives, since the DMV records the restriction removal in their system when ready.
What if I got LASIK and my vision improved — how do I prove it?
You do not need to bring documentation from your eye surgeon. straightforward take the vision test at the DMV. If your uncorrected vision now meets the legal standard, the restriction will be removed. The DMV does not care how your vision improved, only that it meets the requirement.
