They may look alike from a distance, but even identically worded license plates in New Hampshire might be completely different – and that’s a problem for the state’s automated tolling system.

According to The Associated Press, the problem lies in the fact that New Hampshire’s Division of Motor Vehicles allows more than one vehicle owner to have the same wording on their plates, so long as the plate type – such as a veteran plate or moose-emblazoned environmental plate – is different.

To a human patrol officer, the difference in the plates is noticeable. But to an automatic tolling camera – such as the ones used on the state’s toll roads – the war veteran with a “BRN2RN” personalized plate looks the same as the moose lover’s plate with the same wording.

The DMV has put the automated ticketing system, which is manufactured by a Dallas, TX, based company, on hold until they can find a reliable way to identify like-numbered tickets.

Officers told The AP they have no idea how many duplicate plates are out there.
