VA sits in the Mid-tier band. Most U.S. states sit between 30 and 50 percent on the front-window VLT minimum. The numbers vary state by state, so the safe move is to ask the shop to install at or above your state's legal floor and to check the most recent vehicle code text — laws change.

Across all fifty states, the only zone of the windshield where any non-reflective tint is legal is the strip above the AS-1 line — usually four to five inches at the top, marked on factory glass with a small "AS-1" etching. Below that line, windshield tint is not street-legal anywhere in the United States, regardless of state side-glass rules. A reputable shop will measure from the AS-1 line down before laying film, not from the top of the glass.

Laws change. Confirm the most recent VLT minimum directly with the shop and, when in doubt, with the most recent text of your state's vehicle code.

1. Get PPF and tint quoted as separate jobs.Paint protection film and window tint are different installs in different bays with different cure windows. Bundling them on one invoice is fine, but the timeline and warranty paper should be split. Ask which film brand the PPF crew installs (XPEL, SunTek, STEK).
2. Confirm the shop measures front-window VLT before install.A shop that measures with a photometer before installation is the one most likely to keep you legal in your state. If they ask you to sign that compliance is on the customer, that's a quiet yellow flag. Tint stops are 30–50 % on the front in VA.
3. Ask the cure time and what to do during it.Newly installed film cures for 3 to 5 days in summer, 7 to 10 in winter. During cure, do not roll windows down — the film can shift and the squeegee margins can lift. Light hazing or small water bubbles in this window are normal and clear up; bubbles after 30 days are not.
4. Verify the AS-1 line on your windshield before booking strip tint.Across all 50 states, the only zone of the windshield where any tint is legal is above the AS-1 line — usually marked with a small "AS-1" etching at the top of factory glass. Below the AS-1 line, no tint is street-legal anywhere in the U.S., regardless of your state's VLT rule on side glass.
5. Pull a window seal vs. cut on glass — ask what the shop does.Cut-on-glass installs save 15 minutes but risk scoring the rubber seal with a razor. The cleaner method pulls the rear-side or rear-glass window down a half-inch so the cut happens off-glass. It costs the shop time, not money — confirm during the quote.
