Understanding Delaware Window Tint Laws and Regulations

Delaware has specific rules about how dark window tint can be on vehicles. The state measures tint darkness using a metric called Visible Light Transmittance (VLT), which refers to the percentage of light that passes through the tinted glass. Delaware's tint laws apply differently depending on which windows you want to tint on your vehicle.

For the front windshield, Delaware law permits non-reflective tint on the top six inches of the windshield. This means you cannot tint the entire front windshield—only a small strip at the very top is allowed. The front side windows must allow at least 70% of light to pass through, meaning your tint cannot be darker than 30% VLT. The rear side windows have the same requirement of 70% VLT minimum light transmittance.

The rear window (back glass) of your vehicle has different rules. You can use any darkness level of tint on your rear window, including complete blackout tint. This is one area where Delaware residents have the most freedom in customizing their vehicle's appearance.

Delaware also has rules about reflectivity. Window tint cannot be reflective or mirrored in appearance. This means you cannot use metallic or chrome-colored tints that bounce light away from the window. All tint must be applied in a way that looks like standard darkened glass rather than a reflective surface.

These rules exist across all Delaware counties, including New Castle County, Kent County, and Sussex County. Vehicle inspection stations throughout the state use these same standards when checking compliance during vehicle inspections.

Takeaway: Delaware law allows modest tinting on front windows but permits much darker tint on rear windows. Front windows must allow at least 70% light through, while your rear window can be completely darkened.

Medical Exemptions and How They Work in Delaware

Delaware recognizes that some people have medical conditions that require protection from sunlight. The state offers a medical exemption that allows certain individuals to use darker window tint than what standard regulations permit. This exemption acknowledges that conditions like lupus, photosensitivity disorders, and certain skin conditions can make exposure to sunlight harmful.

To obtain a medical exemption in Delaware, you must have a documented medical condition recognized by the state. The condition must be one that causes sensitivity to sunlight or requires UV protection. Your physician or dermatologist must provide documentation stating that you have this condition and that window tinting is medically necessary for your treatment or management of the condition.

The Delaware Division of Motor Vehicles (DMV) processes medical exemption requests. You will need to submit your medical documentation along with your vehicle information. The DMV reviews these requests to determine whether the medical basis supports the need for darker tinting than standard law allows.

Once approved, a medical exemption allows you to install darker tint than the standard 70% VLT requirement on your front side windows. The exact darkness allowed may vary based on your specific medical condition and the supporting documentation provided. The exemption is typically vehicle-specific, meaning it applies to a particular vehicle registered in your name rather than following you between multiple vehicles.

Medical exemption holders should carry documentation of their exemption status when driving. Law enforcement officers may request to see your exemption certificate if they notice tint darker than standard regulations allow. Having your exemption documentation available helps prevent citations and explains why your vehicle's tint exceeds normal limits.

It is important to note that medical exemptions must be renewed periodically. You should check with the Delaware DMV about renewal requirements for your specific exemption, as ongoing medical documentation may be necessary to maintain your exemption status.

Takeaway: Delaware offers medical exemptions for people with conditions requiring sun protection. You need physician documentation and must submit a request to the DMV to receive this exemption for your specific vehicle.

The Window Tint Waiver Process in Delaware

The term "waiver" in the context of Delaware window tint refers to the medical exemption process described above. A waiver allows you to deviate from standard tint regulations when you have a legitimate medical reason. Understanding this process helps you learn how Delaware balances safety regulations with individual health needs.

The waiver request process begins with obtaining medical documentation. Your doctor must examine you and determine that you have a condition sensitive to sunlight. The physician writes a statement confirming your diagnosis and explaining why window tinting is necessary for your health. This medical statement becomes the foundation of your waiver request—without it, the DMV cannot process your request.

After obtaining medical documentation, you will need to complete the DMV's waiver request form. Delaware provides this form through the Division of Motor Vehicles. The form asks for your personal information, vehicle details, and requires you to submit your medical documentation along with the completed paperwork. Some DMV offices allow you to submit these documents in person, by mail, or through other submission methods.

The DMV reviews your submitted materials and determines whether your medical condition meets the criteria for a tint waiver. They may contact you or your physician if they need additional information. The review process typically takes several weeks, so you should not expect immediate approval.

If your waiver request is approved, the DMV issues you a waiver certificate or notation in your vehicle's registration. This documentation proves that your vehicle is legally allowed to have darker tint than standard regulations permit. You should keep this certificate with your vehicle registration and insurance documents.

If your waiver request is denied, the DMV will explain the reason for the denial. You may be able to resubmit with additional medical evidence if you believe your condition was not adequately documented in your initial request.

Takeaway: The waiver process requires medical documentation from your doctor, a completed DMV form, and a review period of several weeks. Once approved, you receive documentation allowing darker tint on your vehicle.

Medical Conditions That May Support a Tint Waiver Request

Several medical conditions are recognized by healthcare providers and state regulations as conditions that may benefit from window tint protection. Understanding which conditions qualify helps you determine whether a waiver request may be appropriate for your situation. However, each case is individual, and your specific physician must make the medical determination for your health.

Lupus is one of the most common conditions associated with window tint waivers. Lupus is an autoimmune disease where the immune system attacks the body's own tissues. Many people with lupus experience photosensitivity, meaning sunlight exposure triggers or worsens their symptoms. Patients with lupus often experience rashes, joint pain, and fatigue that can be triggered or intensified by UV light exposure. For these individuals, window tint helps reduce UV exposure during driving.

Photosensitive disorders represent another category of conditions that may support tint waivers. These are conditions where exposure to light itself triggers symptoms. Some people experience migraines or headaches triggered by bright light. Others have skin conditions where sunlight directly damages or irritates their skin. Conditions like polymorphous light eruption cause skin reactions specifically in response to sun exposure.

Certain medications increase skin sensitivity to sunlight as a side effect. If you take medications like tetracycline antibiotics, sulfonylureas, or certain psychiatric medications, your skin may become photosensitive. This means you burn more easily or experience adverse reactions to sun exposure while taking these medications. Your doctor can document this medication-induced photosensitivity to support a tint waiver request.

Severe acne treatments, particularly isotretinoin (Accutane), cause significant photosensitivity during treatment. Patients taking these medications are advised to minimize sun exposure and protect their skin carefully. Window tint can be part of this protective strategy during the treatment period.

Some people have conditions affecting their eyes that make bright light uncomfortable or painful. Conditions like severe dry eye, keratitis, or photophobia (light sensitivity in the eyes) can make driving in bright sunlight difficult and uncomfortable. Window tint reduces glare and bright light exposure, making driving more tolerable for these individuals.

Takeaway: Conditions like lupus, photosensitive disorders, light-sensitive medications, and certain eye conditions may support a tint waiver request. Your physician must document your specific condition and explain why tinting is medically necessary.
