Oklahoma’s ordinary rule is 25% transmission for side and rear windows. The retrieved statute has specific older-vehicle and licensed-vehicle exceptions, rather than a blanket darker-rear allowance for SUVs.
Read the official sources ↓Rules by window
| Window | Requirement |
|---|---|
| Windshield | Transparent top strip, neither red nor amber, ending at AS-1 or five inches from the top, whichever is closer to the top. |
| Front side | At least 25% transmission and no more than 25% luminous reflectance under the ordinary rule. |
| Rear side | At least 25% transmission and no more than 25% luminous reflectance ordinarily. Pre-1996 vehicles have a 10% rear-transmission allowance, still capped at 25% reflectance and requiring qualifying exterior mirrors; licensed buses and taxicabs have separate exceptions. |
| Rear window | At least 25% transmission and no more than 25% luminous reflectance ordinarily. The pre-1996 rear-window allowance retains the 25% reflectance cap and qualifying-mirror condition; licensed bus/taxicab exceptions are separate. |
Mirrored films and written certification
The allowed device definition excludes mirror-like finishes. Sellers and installers must put a bold written compliance certification in the sale or installation contract, including a warning about other states’ side-window laws.
Medical application
Oklahoma’s DPS Medical Standards Forms page links a tint-exemption application with applicant, vehicle and licensed-healthcare-provider sections. The posted form requires an issued exemption letter; a provider’s recommendation alone is not an exemption. It also warns of possible driving-ability review and daylight-driving restrictions. Because the form retains legacy agency and rule references, confirm the current submission route and permit terms with Oklahoma authorities before sending medical records or installing exempt tint.
Before relying on a special allowance
For the older-vehicle 10% rear allowance, both outside mirrors must provide a view at least 200 feet behind. Have the installer measure the completed window.
Before you rely on this guide
This is general information, not legal advice, a vehicle inspection, or permission to install a particular film. Exceptions and enforcement procedures can depend on your circumstances.
- The live DPS form retains older agency and administrative-rule references. Official rules adopted in 2024 assign exemption letters to Service Oklahoma. Confirm the current submission office and approval terms before relying on the form. A current consolidated-rule check remains incomplete.
- No general SUV/pickup rear-window exception appears in the retrieved section; do not borrow one from another state.
