Yes, you can smile in a driver’s license photo, but keep your lips together. A slight, closed-mouth smile is accepted in nearly every state; a wide, open-mouth grin that shows teeth almost always gets rejected. The reason is technical rather than aesthetic: every state now runs license photos through facial recognition software, and the systems need a near-neutral expression to match your face reliably across images.
Why the Rule Exists
Facial recognition software maps your face as a mathematical template, measuring the distances between landmarks like your eye sockets, cheekbones, jawline, and the corners of your mouth. Modern systems turn those measurements into a numerical fingerprint of your face. When you smile broadly, your cheeks push up, your eyes narrow, and the proportions between those landmarks shift enough to throw off the comparison.
The American Association of Motor Vehicle Administrators, which sets the photo standards most states follow, recommends a “neutral expression” because it “helps matching against other images with non-neutral expressions.”1AAMVA. Facial Recognition Program Best Practices That matching isn’t only for you. Agencies compare your new photo against every other license photo in their database to catch people holding fraudulent duplicate IDs, so consistency across images matters.
The federal REAL ID Act reinforced this. It requires every state to subject applicants to mandatory facial image capture, and the implementing regulation at 6 CFR 37.17 directs states to follow the international photo standard ISO/IEC 19794-5, which calls for a straight, centered, neutral-expression image.2eCFR. 6 CFR 37.17 – Requirements for the Surface of the Driver’s License or Identification Card That is the same standard used for U.S. passports, which is why the rules for the two photos look so similar now.
What Actually Passes
The practical line is simple: closed mouth, no teeth. A slight, natural smile with your lips together is fine in most jurisdictions. What gets rejected is an open-mouth grin, because that is what distorts your facial geometry the most. Exaggerated expressions like frowning, squinting, or raising your eyebrows will also be flagged.
Think relaxed, not robotic. You do not need to look like a mugshot. A gentle, closed-lip smile reads as pleasant on the card without creating problems for the software. The technician will usually tell you if your expression is not going to work before they take the shot.
For reference, the U.S. State Department applies the same standard to passport photos: both eyes open, mouth closed, face aimed directly at the camera. Passport applicants have not been allowed to show teeth since 2004, and driver’s license rules followed a similar path as states adopted facial recognition over the following decade.
Glasses Are Coming Off
If you wear prescription glasses, plan to remove them. The AAMVA best practices recommend against eyeglasses in license photos because “glare affects enrollment” and “heavy glasses affect comparison.” Most states have adopted this as a hard rule rather than a suggestion. Even anti-reflective lenses can produce enough glare under DMV lighting to obscure your eyes, and the AAMVA is blunt about the consequence: “if something blocks the pupils of the eyes, FR results will be inaccurate.”1AAMVA. Facial Recognition Program Best Practices
Sunglasses are never allowed. Tinted lenses, transition lenses that have not fully cleared, and colored contacts that alter the appearance of your iris will all cause problems. If you have a documented medical condition requiring you to wear glasses at all times, you can typically request an exception with supporting documentation from your doctor.
Head Coverings and Religious Exemptions
Hats, scarves, bandanas, and other headwear come off unless you wear a head covering for sincerely held religious beliefs or a documented medical condition. Every state offers some form of religious exemption, though the process varies. Some states ask you to sign an affidavit attesting that your religion requires the covering; others allow it without formal paperwork as long as your full face remains visible.
The AAMVA guidelines set clear boundaries even when headgear is allowed: “the chin, ears, and forehead should be visible.”1AAMVA. Facial Recognition Program Best Practices The covering also cannot cast shadows across your face. In practice, it can frame your face but cannot drape over your forehead or hide the sides of your face near your ears.
Other Rules That Can Trip You Up
Expression and eyewear get the most attention, but a few other requirements matter at the counter:
- Face the camera straight on, with both eyes open. No head tilt, no looking off to the side. The AAMVA describes the ideal pose as your face being “perpendicular to an imaginary plane formed parallel to the front surface of the face,” which is a technical way of saying: aim your nose at the lens.1AAMVA. Facial Recognition Program Best Practices
- Hair should not fall across your face or cover your eyes. Tucking it behind your ears helps.
- Only you can appear in the frame. No children on your lap, no bags over your shoulder, no visible headphones.
- Facial piercings and heavy jewelry sit in a gray area. Most states do not have an explicit written ban, but a technician can ask you to remove anything that obscures your features or creates glare. Small studs are rarely an issue; large hoops or chains across your face will be.
If Your Photo Comes Out Badly
You are not stuck with a bad photo forever, but fixing it is not free or instant. In most states, you have to request a duplicate or replacement license and take a new photo at that time. You generally cannot request a retake during the same visit after the card has been processed. You wait for the card to arrive, return to the DMV, and pay the replacement fee.
Replacement fees vary widely by state, typically between $5 and $40. The visit has to be in person because you need to be photographed again. Some states will only issue a new photo if you are already making another change to your license, such as an address update, or if your license is close enough to expiration that you may as well renew. Check your state’s DMV website before making the trip.
While you wait for the new card, most offices issue a temporary paper license without a photo. That document is valid for driving but may not be accepted as photo ID for other purposes, like boarding a flight.
Small Things That Help
Wear a solid-colored top that contrasts with the background. Avoid white and very light blue, which are the most common backdrop colors and will wash you out. Darker, saturated colors work best.
Practice your expression in a mirror beforehand. Aim for a relaxed, closed-mouth look where your jaw is not clenched. If you tend to look stiff in photos, try exhaling just before the technician takes the shot. Take your glasses off before you reach the counter so you are not fumbling at the last second, and push your hair away from your face and ears.
If the lighting at your DMV office is harsh, a light layer of translucent powder can cut down on shine without changing your appearance. The goal is a photo that looks like you on a normal day. That is what identification requires, and it is what the facial recognition system matches best.
