depends on where you live if you get hassled or not.
I ran around for 3 years in my old ranger and never got stopped.. I had 5% too... but i had DWB so it wasnt a whole lot of contrast. lol.
as soon as i bought my current ranger (about a year ago now) I put 5% on it as well, but being silver, its easy to spot the dark tint. I got stopped once in fairfax and was metered at 3% but im going to wait to see if I get pulled again before i remove it.
