Pennsylvania is one of the strictest states for tint: passenger cars need at least 70% VLT on the front side windows, the rear side windows, and the rear window alike — there's no darker option for a sedan's back glass. SUVs, vans, and trucks get relief only behind the driver, where any darkness is legal with dual mirrors; their front side windows still need the same 70%. This is set by 75 Pa.C.S. Section 4524, applied the same statewide.
Pennsylvania VLT limits by window
- Front side windows (driver + front passenger), all vehicles: must allow at least 70% VLT.
- Rear side windows and rear window, passenger cars: also at least 70% VLT — Pennsylvania doesn't relax the standard behind the driver on a sedan the way most states do.
- Rear side windows and rear window, SUVs/vans/trucks: any darkness, provided the vehicle has dual outside mirrors.
- Windshield: a non-reflective strip is allowed only on the top 3 inches — one of the narrowest windshield allowances in the country — with the rest of the glass held to the same 70% VLT.
- Reflectance: reflective and mirrored tint is banned outright on every window, regardless of vehicle type.
Medical exemptions Pennsylvania requires more than a doctor's note: a physician or optometrist documents the qualifying condition, but PennDOT itself issues the certificate of exemption, and that state-issued certificate — not the doctor's letter alone — has to be carried in the vehicle at all times.
Enforcement and penalties Illegal window tint is a summary offense under the Pennsylvania Vehicle Code, with a fine of up to approximately $110 and no criminal record or jail exposure for the driver.
What this means when you're quoting a job Pennsylvania's 70% floor applying to a sedan's rear glass, not just the front, is the detail that trips up installers coming from a state where the back can go dark regardless of the front — quoting a "dark rear package" on a customer's sedan here is quoting something the statute doesn't allow. The narrow 3-inch windshield strip is the second trap, tighter than the 4-6 inch allowance common elsewhere. A [window tint shop software](/industries/tint) tool that holds a sedan's rear glass to the same 70% as the front, and flags SUVs/vans separately, keeps a quote from drifting into Pennsylvania's stricter-than-typical territory.
