A Washington state man says he just paid more than $18,000 in bridge tolls for his son who crossed the 520 bridge daily for work but never got a Good To Go pass.

KING-TV reports that Tom Rose's son thought he would be billed for the tolls and that he could pay later.

His son never received a bill. He learned the total of what he owed when he tried to sell his car: more than $18,000. That's $1,360 in tolls and more than $16,000 in penalties.

The department says they tried to bill Rose but their letters were returned. He will have to pay the tolls, but officials say they will try to work something out concerning the penalties.

KING-TV reports a lawyer has filed a class-action lawsuit against the department concerning its policies.
