New customers using an E-ZPass Maryland transponder will no longer have to pay the $7.50 transponder fee. Eliminating the transponder fee will put $46-million back into Marylanders’ wallets over the next 5 years. The free transponders eliminate $6 million in fees and provide new E-ZPass Maryland customers $40 million in toll discounts over the next five years. Also – the Maryland Department Transportation Authority will replace nearly 400,000 aged transponders that are currently in circulation at no cost to customers. If you bought a transponder this year – you’ll be issued a $7.50 credit in the next several weeks as long as your account is registered and in good standing.
