Relating to the authority of a local authority to install a temporary traffic-control device on certain highways.

HB 1624 allows local governments (like cities or counties) to temporarily install traffic signs or signals on state highways without Texas Department of Transportation (TxDOT) permission when an existing device breaks. To do this, they must notify TxDOT of the temporary device, remove it as soon as the original device is fixed, and only use it while the original device is inoperable. The bill amends Texas Transportation Code sections 544.002 and 553.002 to create this exception, affecting local traffic management on state highways. It takes effect September 1, 2025.
