Relating to the use of a high occupancy vehicle lane by an operator of a motor vehicle who is pregnant.

HB 3539 allows pregnant drivers in Texas to use high occupancy vehicle (HOV) lanes regardless of how many people are in their vehicle, as long as only the unborn child (not additional passengers) is present. This bill amends the Texas Transportation Code to specifically exempt pregnant operators from standard HOV lane occupancy requirements. The law directly affects pregnant drivers who operate vehicles on Texas highways, removing the need for a second passenger to legally use these lanes. It takes effect September 1, 2025.
