Relating to the use of dynamic message signs for the Keep 'Em Safe Texas Gun Storage Campaign.

HB 737 requires the Texas Department of Transportation (TxDOT) to work with the Department of Public Safety (DPS) to use existing highway dynamic message signs for the "Keep 'Em Safe Texas Gun Storage Campaign," providing public information about safe firearm storage. The bill mandates TxDOT to implement this using current signage systems across the state, unless federal transportation authorities threaten loss of funding or penalties for noncompliance. It does not create new requirements but directs existing resources toward promoting safe gun storage practices. The law takes effect on September 1, 2025.
