This bill would additionally authorize the department to allow the registration, or renewal or transfer of registration, for low-use vehicles and agricultural vehicles that meet certain requirements. Existing law authorizes the department, in its discretion, to issue a temporary permit to operate a vehicle when a payment of fees has been accepted in an amount to be determined by the department and paid to the department by the owner or other person in lawful possession of the vehicle. Existing law authorizes the department to issue a temporary permit to operate a diesel-fueled vehicle for which registration may be refused pursuant to specified emission standards requirements. This bill would additionally require the department to issue the permit within 48 hours of a determination of noncompliance with current emission requirements.
