FOR AN ACT ENTITLED, An Act to  revise the requirements for the location of side exhaust on certain motor vehicles.
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF SOUTH DAKOTA:
     Section  1.  That § 32-15-17 be amended to read as follows:
     32-15-17.   No person may drive a motor vehicle on a highway unless the motor vehicle is equipped with an exhaust system and a muffler both in good working condition and in constant operation to prevent excessive or unusual noise.

     Exhaust systems on passenger or passenger-carrying vehicles used on any highway shall discharge the exhaust fumes at a location to the rear of the vehicle body or direct the exhaust fumes outward from the side of the vehicle body at a location rearward of any operable side windows. Any motor vehicle equipped with side exhaust according to the original vehicle manufacturer specifications is exempt from the location requirements. A bus used for the purpose of carrying school children may discharge the exhaust on the left side in front of the rear axle.

     Exhaust systems on property-carrying vehicles used on any highway shall discharge the

exhaust fumes at a point rearward of the passenger-carrying compartment.

     No person may use a " muffler cut-out " on any motor vehicle upon a highway.

     A violation of this section is a Class 2 misdemeanor.
