When you are qualified we send you a list of specifications you can take to any window tint shop so they can narrow down which type of tints you can put on your vehicle and be legally exempt.
If you have an existing tint you can take your vehicle to any tint shop and show them these specifications to have them meter the tint on your windows to see if your existing tint meets the exemption requirements.
