Why does Colorado have 2 different laws?

On my tint chart it shows CO as having 2 very different laws, I think I heard why once but I forget now. Anyone?

my guess would be, one for passenger vehicles and one for multi-purpose vehicles...like every other state.

I take it your not from CO with 22 yrs experience otherwise you would know the law. Two part law. IF the fronts are tinted the whole car cannot be below 27 vlt. IF the fronts are NOT tinted murder that biotch out. oh yea 6 inch max visor strip.

kinda cool law

That doesn't sound too bad...........

my chart say's no for the front and any for the back with 4" strip on one
and the other say's 27 all the way around with a 4" strip
this is crazy but it doesnt say where in co.

The strip is 6"inch now I believe it changed a year or so ago, but hell if I can find it now.
