FasTrak for Every Driver

FasTrak Flex Toll Tag

Most vehicles need a FasTrak Flex toll tag, which allows carpools and motorcycles to receive free or discounted tolls in express lanes. Just set the toll tag to indicate the number of people in your vehicle before you start your trip.

  • Solo drivers must set the toll tag in the ‘1’ position, and pay full-price tolls.
  • Carpools must have the FasTrak Flex toll tag set in the '2' or '3+' position based on the number of people in the car to get their toll discounts on express lanes.
  • Vanpools and motorcycles must have the FasTrak Flex toll tag set in the '3+' position to get their toll discounts on express lanes.

*Note: At toll bridges, carpools must use the designated carpool lane with a valid FasTrak toll tag – either a standard or FasTrak Flex toll tag.

Standard FasTrak Toll Tag

FasTrak no longer issues standard tags. Existing tags will be phased out by January 1, 2027. Until phase-out, solo drivers can use standard tags in all express lanes to pay full tolls.

Standard tags cannot be used by carpools, vanpools, or motorcycles to receive express lane toll discounts.
