In Texas one can always spot a "northern" car whether they have gotten Texas plates or not, by looking at their windows....no dark tinting!
Can't imagine driving a car in Texas without window tinting.
Although, there are those on the shady-side whose windows are way too dark .. pun intended.
Texas inspection law used to have limits on depth of window tinting but apparently they have not been enforcing it for many years now.
They should.
