Interesting...
The statute describes view-obscuring "COLOUR" or "REFLECTIVE" material. However, if dark tint is not considered reflective, than I should be able to use it to protect my interior from harmful UV rays, No?
If the sole purpose of this section was to make certain that law enforcement can see the driver at all times, then why doesn't it just say that? (ex. "No material shall be place on any side window which would prevent the interior of the vehicle from being viewed from the outside?). The fact the the words "colour" and "reflective" are used seems to leave room for argument about whether all dark tint is "reflective". In fact, many tints actually "ABSORB" most of the light, and reflect very little.
Lets assume this definition of "reflection" applies to this statue:
"Reflectance" means the ratio of the amount of total light, expressed
in a percentage, which is reflected outward by the product or material
to the amount of total light falling on the product or material.
Now take a look at this site (http://www.snaptint.com/help.php?section=specs) and note the "reflection" vs. "absorption" numbers. Note that some tints actually ABSORB most of the light while REFLECTING very little. Visibility from the outside is definitely diminished, but by means of "absorption", not "reflection" as specified in the Act. So on the face of it, it would appear there are legal ways of obscuring the view of the interior.
This section also fails to specify the technical conditions necessary for "viewing" from the outside. Perhaps I could assume it means a small peephole could be cut out of the tint which would satisfy this section by allowing an officer to see in when his eyes are only an inch or less from the glass!
Keep in mind, interiors are not visible to the naked eye at night! So why is the daytime treated so differently? If the answer is that an officer can use his flashlight to observe an interior at night, then can we not just install sufficient interior lighting for illumination at a traffic stop?
I can imagine an awful lot of minorities don't want to be profiled as they drive by, just by the colour of their skin and wish to push the tint-level up as high as possible.
Also, visibility through tint changes as weather and lighting conditions change. What might be legal at 12:00 noon on a sunny day may become illegal at 8:00pm on an overcast evening.
Lots of stuff to consider when planning a defense.
