Each E-ZPass tag is specifically programmed for a particular class of vehicle, and while any valid, working tag will be read and accepted in any E-ZPass toll lane, the wrong toll amount will be charged if the tag's programmed vehicle class does not match the vehicle. This will result in a violation and possible large fine assessed to the tag holder, especially if a lower-class (e.g., passenger car) tag is being used in a higher-class vehicle such as a bus or truck. In an attempt to avoid this, E-ZPass tags for commercial vehicles are blue in color, contrasting with the white tags assigned to standard passenger vehicles. The blue E-ZPass is also used in government employee vehicles. In New York, an orange E-ZPass tag is issued to emergency vehicles as well as MTA, PANYNJ, and Thruway Authority employees.
