AN ACT DECOUPLING THE STATE'S LIGHT DUTY MOTOR VEHICLE EMISSION STANDARDS FROM THE STANDARDS OF CALIFORNIA.

SB 315 would amend state law to stop automatically adopting California's light-duty vehicle emission standards for new cars and small trucks sold in the state. This bill directly affects the state's vehicle regulations and future emissions rules for manufacturers and consumers. It does not create new standards but severs the current legal link to California's requirements, allowing the state to set its own rules moving forward. The bill is procedural, focusing on regulatory separation rather than policy changes.
