Delaware window tinting legal limits and medical exemption certificates can save you from fines and failed inspections if you know the rules. Many drivers assume darker tint is fine, but Delaware’s laws are strict, and non-compliance means trouble during inspections or traffic stops. The state sets clear visible light transmission (VLT) percentages, and only approved medical exemptions bypass these limits.
As of 2026, Delaware requires at least 70% light transmission for front and rear side windows, with no tint allowed on the windshield except a 5-inch sunstrip.
Quick Answer
Delaware window tinting legal limits and medical exemption certificates allow 70% VLT on all side and rear windows. Windshields cannot have tint except a 5-inch sunstrip at the top. Medical exemptions remove VLT restrictions but require a physician’s certificate.
Non-compliant tint risks inspection failure and fines.
The Truth About Delaware Window Tint Laws (Why Accuracy Matters)
Delaware’s tint laws exist for safety. Darker windows can obscure a driver’s view, especially at night or in poor weather. Law enforcement actively checks tint compliance during traffic stops, and inspection stations will reject vehicles that don’t meet the standards.

These rules aren’t just suggestions. The Delaware Division of Motor Vehicles (DMV) enforces them under Title 21 of the Delaware Code. Ignoring them can lead to fines, mandatory tint removal, or even court appearances.
For drivers with medical conditions, the state provides a legal pathway to darker tint, but the process requires documentation.
Legal VLT Limits for Every Window on Your Car
Visible Light Transmission (VLT) measures how much light passes through your window tint. Delaware’s limits are straightforward but strict.
| Window | Minimum VLT % | Notes |
|---|---|---|
| Front side windows | 70% | Must allow at least 70% light in |
| Rear side windows | 70% | Same as front sides |
| Rear window | 70% | No exceptions for sedans |
| Windshield | 0% (no tint) | 5-inch sunstrip allowed at top |

The 70% rule means your tint can only block up to 30% of light. Anything darker is illegal unless you have a medical exemption. Factory-tinted glass often meets this standard, but aftermarket tint usually doesn’t unless it’s very light.
What's Banned: Reflectivity, Colors, and Windshield Rules
Delaware prohibits more than just dark tint. Reflectivity is another major concern. Tint that’s too reflective can blind other drivers, especially at night.
The state bans metallic or mirrored finishes that create a mirror-like effect.
Color restrictions also apply. Tint in red, amber, or blue is illegal because these colors are reserved for emergency vehicles. Neutral colors like gray, charcoal, or black are permitted as long as they meet the VLT requirements.
For windshields, the rule is simple: no tint is allowed except for a 5-inch non-reflective strip at the top. This sunstrip must also allow at least 70% light transmission. Any tint below this strip is a violation.
Medical Exemption: Who Qualifies and What It Covers
Not everyone can tolerate bright sunlight due to medical conditions. Delaware allows exemptions for drivers or passengers with documented light sensitivity. Common qualifying conditions include lupus, melanoma, and severe photosensitivity.

To qualify, a licensed physician must certify that the individual requires darker tint for medical reasons. The exemption removes the 70% VLT restriction, but the tint must still comply with other rules, such as no reflective or colored tints. The certificate must be carried in the vehicle at all times.
How to Apply for a Delaware Tint Medical Exemption Certificate
Start with a licensed physician. They must confirm your condition requires darker tint and specify the medical necessity. The Delaware DMV provides a form for this certification, which your doctor completes and signs.
Next, submit the form to the DMV in person or by mail. Include your vehicle registration and a copy of your driver’s license. The DMV reviews the application and issues the exemption certificate if approved.
Keep this document in your vehicle at all times.
The certificate is vehicle-specific. If you change cars, you’ll need to reapply. The exemption doesn’t expire unless your medical condition changes or you no longer own the vehicle.
The Risks of Running Illegal Tint in Delaware
Driving with non-compliant tint can lead to a traffic stop. Police use tint meters to check VLT percentages on the spot. If your windows fail the test, you’ll likely receive a citation.
Fines start around $25 but can go higher for repeat offenses. More importantly, your vehicle will fail its annual inspection until the tint is removed or replaced. This means you can’t renew your registration until the issue is fixed.
Insurance companies may also take notice. Some policies include clauses about vehicle modifications, and illegal tint could void coverage in an accident. The cost of removing and replacing tint often exceeds the fine itself.
How to Ensure Your Tint Is Compliant
The easiest way is to check before installation. Ask your tint shop to confirm the VLT percentage meets Delaware’s 70% rule. Reputable shops know the local laws and can provide compliant options.

If your car already has tint, use a tint meter to verify. These devices are available at auto parts stores or inspection stations. Measure each window, including the windshield sunstrip.
For DIY installations, follow the manufacturer’s guidelines. Use a high-quality film and apply it evenly to avoid bubbles or peeling. Poor installation can reduce visibility and still lead to a citation.
Expert Advice: Choosing the Right Tint and Installer
Not all tint is created equal. Ceramic films offer the best UV protection and heat rejection without darkening the windows too much. Dyed films are cheaper but may fade over time.
Look for an installer with experience in Delaware’s laws. They should offer a warranty on their work and use compliant materials. Ask for references or check online reviews to ensure quality.
Avoid shops that push darker tints without discussing exemptions. A good installer will explain the legal limits and help you stay within them.
