SB 936 -- MOTOR VEHICLE EMISSIONS INSPECTIONS This bill allows motorists to operate their vehicle for 30 days after the vehicle's registration expires for the purpose of resetting the vehicle's readiness monitors to pass the on-board diagnostic emission inspection. Motorists must keep a copy of the most recent failing diagnostic test results in their vehicle to present to law enforcement. Motorists will still be required to pay any late registration penalties.Copyright (c) Missouri House of Representatives
