Traffic Safety - As enacted, clarifies the areas in which a personal delivery device may be operated and where such devices are prohibited; authorizes local resolutions or ordinances to both regulate and prohibit such devices but only in compliance with state law. - Amends TCA Title 55, Chapter 8.

SB 1625 allows personal delivery devices (like delivery robots) to operate on bicycle paths, shoulders, parking lots, and areas adjacent to roadways across Tennessee, overriding local government bans. It removes local authority to prohibit these devices entirely, instead permitting only safety-related regulations that align with state rules. The bill sets a 20 mph speed limit for such devices and grants them pedestrian or bicyclist rights depending on where they operate. This directly affects delivery companies and local governments, standardizing rules statewide starting July 1, 2026.
