HB 469 amends Section 644.101(c) of the Transportation Code to expand eligibility for sheriffs and deputy sheriffs in certain counties to apply for certification to enforce commercial motor vehicle safety standards. The bill includes counties that contain an international port, have specific population ranges and geographical characteristics, or generate significant tax revenue from oil and gas production. These updates aim to enhance the enforcement of commercial motor vehicle safety standards in strategic areas, such as counties near international borders and major transportation corridors, addressing changing demographic and economic conditions in Texas and ensuring increased oversight in regions with substantial commercial activity. The act takes effect on September 1, 2025.
