Notice regarding windshield mounting legal restrictions:

Before using the suction cup mount on your windshield, check the state and local laws and ordinances where you drive. Some state laws prohibit drivers from using suction mounts on their windshields while operating motor vehicles. Other state laws allow the suction mount to be located only in specific locations on the windshield. Many other states have enacted restrictions against placing "non-transparent material" on the windshield or placing objects on the windshield in locations that obstruct the driver's vision.
