All tolling authorities set their own fines for driving on toll roads without a toll tag and may charge late fees.
The North Texas Tollway Authority charges violators at least 50 percent more than drivers with toll tags, according to NTTA officials, and late charges apply.
The Texas Department of Transportation receives funding from toll roads owned and maintained by the state, including the Grand Parkway in Houston and SH 130 in Austin. The NTTA operates many of the toll roads in the Dallas area.
Motorists who use TxDOT toll roads without a tag are charged the toll road price and a $1.50 mailing fee, according to officials with TxTag, TxDOT’s toll-collection system. Past-due payments incur a $4 monthly late fee and can result in a $250 court fine.
Violators may also be notified by law enforcement if they continue using toll roads. The safest option, according to TxDOT, is to pay tolls by the due date.
