Do I need a MacPass tag for each vehicle?
Yes, you must have a MacPass tag for each vehicle. MacPass tags must be placed on the inside of your windshield just below the rear-view mirror to work most efficiently. MacPass are not allowed to be moved from one vehicle to another. You can have multiple tags on your account, and you will be required to enter individual vehicle information for each MacPass tag. If a MacPass tag is removed from the windshield after being adhered, the tag will no longer work and must be replaced.
