  • They aim to reduce unsafe driving behaviors, such as crossing the solid line, weaving in and out of the Express Lanes and other violations.
  • Weaving in and out of the Express Lanes or crossing the solid line can yield up to a $1,000 fine and points off a driver's license.

Drivers are never forced to pay a toll; they can always use free general purpose lanes. The enforcement is on!
