Express Lanes Safety Tips

  • Speed limits apply to the Express Lanes as well as the general purpose lanes. Motorists should not exceed the posted speed limits when using the Express Lanes.
  • Express Lanes should be entered and exited through the dashed line only. Weaving in and out of the Express Lanes and crossing the double white line could result in a violation and up to $1,000 fine.
  • Express Lanes should NEVER be used as a passing lane. Express Lanes are offered next to the free general purpose lanes to provide drivers with a choice and an option of reliable travel time, but it’s not safe to use Express Lanes as a passing lane.
  • While it might be tempting to use the Switchable HOV Transponder to avoid paying tolls, it is important to remember there is enforcement on the roadway. Our local law enforcement officers are out on the corridors; violations could cost up to $250.
