After fielding thousands of complaints, Virginia officials on Monday said only new E-ZPass holders would be charged a monthly fee and not those who already have such passes.

The compromise means new customers will have to pay 50 cents a month for each standard transponder or $1 a month for each Flex transponder, which allows carpooling drivers to use express lanes for free, according to the Virginia Department of Transportation. Drivers would begin paying the fees Sept. 1.
