The AS-1 line on your windshield: what Louisiana tint law actually allows
Louisiana allows tint on a front windshield in one place only: above the manufacturer's AS-1 line, or in the top five inches of the glass. It has to be non-reflective. That comes from La. R.S. 32:361.1, which also says no object or material may be placed on or affixed to the front windshield or the front side windows in a way that obstructs or reduces the driver's clear view. The statute applies to vehicles built on or after January 1, 1994. Film applied below the AS-1 line is not legal, and it does not become legal because the previous owner did it.
The part most drivers here learn the hard way is on replacement day. A tint strip lives on the glass, not on the car. When the glass goes in the dumpster, the strip goes with it.
Finding the AS-1 line on your own windshield
Sit in the driver's seat and look at the top corners of the glass, usually on the passenger side near the edge, sometimes on both sides. You are looking for a small etched or printed marking that reads AS-1, part of the block of stamped codes on the glass. Draw an imaginary horizontal line across the windshield from that mark. Everything above it is the zone Louisiana lets you tint.
On most vehicles that line sits just below the bottom edge of the interior mirror mount, which is why factory shade bands look the way they do. If your glass has no visible AS-1 marking, the statute's other measure applies: the top five inches. Measure down from the top edge of the glass itself, not from the headliner trim.
That is a narrower band than people expect. It is enough to cut the glare off the top of the sky. It is not enough to darken the part of the windshield you actually look through on Perkins Road at five in the afternoon.
Why drivers in this metro want a strip in the first place
There is a real reason sun strips are popular here and it is not cosmetic. Baton Rouge summers run from late May into early October with highs routinely in the 90s and a heat index that climbs past 100 for weeks at a stretch. A car parked in an open lot off College Drive or in the gravel at a plant gate in Gonzales turns into an oven, and the windshield is the biggest solar panel on the vehicle.
Glare is the other half of it. Westbound I-10 over the Horace Wilkinson Bridge in the late afternoon puts the sun directly in your face with the river throwing light back up at you, and the current widening work through the corridor means you are doing it at reduced speed in a narrowed lane rather than rolling through. A legal band at the top of the glass helps with the sun sitting high. It does nothing for the sun sitting low, which is when you actually need the visor.
Everything else people stick to a windshield
The obstruction language in R.S. 32:361.1 is not limited to film. It covers objects and materials placed on or affixed to the front windshield and front side windows that obstruct or reduce the driver's clear view. In practice that is a long list around here.
Contractor and plant access hang tags for the petrochemical corridor along LA 30 and the river. Port district credentials in Port Allen. LSU parking decals and the stack of old ones nobody scraped off. Suction phone mounts in the middle of the glass. Toll and gate transponders. Dash cams mounted low instead of up behind the mirror. None of that is automatically illegal, and none of it is automatically fine either. The test in the statute is whether it obstructs or reduces your clear view, and a windshield that is already cracked plus a mount in the sight line is a much easier stop for an officer to justify than either one alone.
The cheap fix is to move everything you can into the shaded band at the top or down behind the mirror, and scrape the dead decals.
Replacement day: the strip does not transfer
Two different things get called a tint strip and they behave differently when the glass is replaced.
Some windshields come from the factory with a tinted band built into the glass itself. If yours does, the replacement glass needs to be ordered with the same band. That is a part number question, and it is worth asking before the appointment rather than discovering it when the new glass is already in.
Aftermarket film is the other case. It was cut and applied to your specific piece of glass by somebody with a squeegee, and it cannot be peeled off and reused. If you want it back, it has to be applied fresh to the new windshield, and it has to go back above the AS-1 line to be legal. If the film on your old windshield ran below that line, the honest answer is that redoing it the same way puts you back out of compliance. Baton Rouge glass takes a beating in the I-10 construction zone and behind the loaded trucks on Airline Highway, so odds are decent this is not your last windshield. Getting the strip right once saves the argument later.
One more replacement-day note: the area at the top of the glass behind the mirror is crowded on newer vehicles, because that is where the forward-facing camera for lane keeping and automatic braking sits. If you are having film applied and your vehicle has that camera, tell the installer before they cut anything.
The brake tag is gone. This law is not.
House Bill 1085 ends inspection stickers for personal vehicles registered in Louisiana on January 1, 2027, and since June 30, 2026 law enforcement has not been able to cite a driver solely for failing to display one. In East Baton Rouge, West Baton Rouge, Livingston, Iberville and Ascension parishes, emissions testing continues under federal air-quality rules, so drivers in this five-parish area still have something periodic on the calendar when most of the state does not.
What matters here is that the sticker regime and the obstructed-view statute were always two separate things. R.S. 32:361.1 did not change. An officer on Florida Boulevard or at the Range Avenue interchange can still stop you for glass or film that makes it hard to see out, brake tag or no brake tag.
Questions we get about tint and glass
Can I have a strip applied to a brand new windshield? Yes, as long as it is non-reflective and stays above the AS-1 line or within the top five inches.
My truck is a 1992. Does any of this apply? The statute as written covers vehicles manufactured on or after January 1, 1994. Older vehicles sit outside that provision, though the general obstruction concern and basic visibility still matter.
Will the emissions test in East Baton Rouge Parish check my tint or my cracked windshield? Reporting on the transition indicates what remains in the five parishes is emissions testing, not a full safety inspection. We are not going to tell you windshield condition is part of it, because that has not been verified. Fix the glass because you have to see through it.
My insurer gave me a shop to use. Do I have to? No. La. R.S. 22:1892 prohibits an insurer from requiring that glass repair or replacement be done at a particular shop, and an insurer that recommends a network has to tell you that using it is optional.
If your windshield is due for replacement and it had a tint strip on it, mention that when you ask for a quote so the glass gets ordered correctly the first time. Call or send a quote request with your year, make, model and whether there is a camera behind the mirror, and we will tell you what your options look like.
