WESTFIELD, Mass. (WWLP) – Starting Friday, you’ll pay Massachusetts Turnpike tolls through your E-ZPass transponder, and how you register your E-ZPass account matters. If you do it wrong, you’ll rack up fines.

If you drive the Mass Pike without a transponder, you’ll get a bill in the mail with a surcharge. Transponders are accepted throughout New England, New York, Pennsylvania, and several other state toll roads across the country. It takes five days to activate a transponder, so if you ordered one this week, it might not scan when E-ZPass goes live Friday night.

The MassDOT said as soon as you get one of these transponders, you’re not allowed to share it with anybody unless the license plates of the cars you’re switching it between are all registered under the same account. The overhead gantries take pictures of your license plate, and they match it up to the transponder. If the two don’t match, you’ll receive a fine. So you can only use a transponder in your registered vehicle, you can’t share.

“I think they’re going to get caught. I think they need to have their own and not fight the system,” said Hellen Johnson of West Springfield.

If you plan to use it in a rental cars, that vehicle must be added to your account. Leased cars must be added as well, and if you get a violation, it’s sent directly to the leasing company.

You don’t need a separate transponder on a trailer you tow, but the trailer’s plate must be registered on your account. Families can have up to four separate transponders on one account.

They also have E-ZPass transponders for motorcycles.
