Highways, Roads and Bridges - As introduced, requires TACIR to study overall road safety and submit its recommendations to the chair of the committee in the house of representatives with jurisdiction over transportation matters, the chair of the transportation and safety committee of the senate, and the legislative librarian on or before January 15, 2026. - Amends TCA Title 4; Title 54 and Title 55.

HB 1224 requires Tennessee’s TACIR (Tennessee Advisory Commission on Intergovernmental Relations) to study road safety for all users - including drivers, pedestrians, cyclists, older drivers, teens, and transit riders - by identifying safety challenges per group and recommending behavior improvements and safety technologies. TACIR must submit its report with specific recommendations to transportation committee chairs in both legislative chambers and the legislative librarian by January 15, 2026, using existing agency resources. This bill does not fund new programs or change current laws; it mandates a study to inform future policy decisions. It directly affects TACIR’s work and indirectly informs legislative action on road safety.
