Windshield mounts illegal in 28 states?
In a surprising (and questionable) bit of gumshoe work, a POI Factory contributor has concluded that windshield mounts are illegal in 28 states and six Canadian provinces.
According to the article, windshield mounting is against the law in the states shown in red, and limited placement is allowed in specific windshield zones in the states in yellow. Green should mean you’re good to go, but I’d take it all with a grain of salt. The commenters on one site linking to the post found quite a few errors and/or misinterpretations. If you have questions, I’d advise you to follow the links below and read the law for yourself.
As for me, I prefer friction/dashboard mounts. While they can still be placed in such a way as to block your view, technically they aren’t attached!
Yes – GPS receivers can be mounted on the windshield. This is either through being specifically mentioned as being exempt from a regulation, or through the law not specifically mentioning GPS receivers at all while mentioning other items as being prohibited. See the appropriate law for details.
Yes (Limited) – As “Yes” above, but the law limits the location where the receiver may be mounted, usually at the bottom of the windshield in a 5″ square on the driver’s side or a 7″ square on the passenger’s side. See the appropriate law for details.
No – GPS receivers may not be mounted on the windshield. This is generally because of a mention of “non-transparent material” not being allowed on the windshield. A GPS mount would fall under this definition. See the appropriate law for details.
