HB 2266 amends Tennessee law to increase the penalty for vehicular homicide from a Class C felony to a Class B felony when the death results from a driver traveling more than 20 miles per hour over the posted speed limit. The bill directly affects drivers whose extreme speeding (defined as exceeding the speed limit by 20+ mph) causes a fatal crash. It creates a specific speed threshold ("extreme and excessive rate of speed") and upgrades the felony classification for such cases. This change applies to prosecutions under Tennessee Code Annotated Sections 39-13-213(a)(5) and (b)(4), effective July 1, 2026.
