Tags must remain in the registered vehicles. If a tag is not read, the agency's new video enforcement will scan a license and match it with an existing account. Rental cars, for example, will not match an existing tag, which could result in penalties for the tag holder. Not any more. Problems can be averted in many cases because tag users can get up to three tags per account, Ms. Borst noted.
Tags are free, and the agency charges lower tolls for tag users than cash customers.
Tag users who use credit cards for tag billing should ensure that their tag accounts have valid credit-card numbers for the agency to use. If the credit card that has the toll tag account is about to expire, the motorist must update the information with the toll agency. Tollway officials typically send a warning letter for those cases, Ms. Borst said. The authority updated toll-dodger enforcement a few months ago. Video enforcement began in earnest around the first of the year with the opening of higher-speed express lanes along the President George Bush Turnpike.
