There seems to be a lot of confusion as to which states or provinces/territories allow a GPS receiver to be mounted to a windshield and which do not. There have been various claims that say all states allow such mounting to only select states permitting. A lot of the confusion is due to selective enforcement of the law, such as in the example case here, where a New Jersey driver was pulled over for a non-existent infraction and fined by the officer for having the GPS mounted. It was because of the example case that I set out to determine what the law actually says regarding windshield placement of a GPS. The results are rather surprising in that 28 US states and 6 Canadian provinces or territories do not permit the GPS to be mounted on the windshield.
For the list below, the results are determined based upon the letter of the law in each state or province as well as the doctrine of "everything which is not forbidden is allowed."

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.
