Exhaust systems shall comply with the Vehicle Code and the
following:
(a) Every motor vehicle propelled by an internal combustion engine shall be equipped with a
system to direct the discharge of combustion exhaust gases.
(b) No part of an exhaust system shall be
located where its position would likely result in burning, charring, or damaging the electrical wiring, the fuel supply, or any combustible part of
the motor vehicle.
(c) No exhaust system shall discharge to the atmosphere at a location directly below
the fuel tank or the fuel tank filler pipe unless a shield is installed in a manner that prevents spilled fuel from contacting the exhaust
system.
(d) The exhaust system of a Type 1 bus, other than a school bus, powered by a gasoline engine
shall discharge to the atmosphere at or within 6 inches forward of the rearmost part of the bus.
(e) The
exhaust system of a Type 1 bus, other than a school bus, using fuels other than gasoline shall discharge to the atmosphere either:
(1) At or within 15 inches forward of the rearmost part of the vehicle, or
(2) To the rear of all doors or windows designed to be opened, except windows designed to be opened solely as
emergency exits.
(f) The exhaust system of every truck and truck tractor shall discharge to the
atmosphere at a location to the rear of the cab or, if the exhaust projects above the cab, at a location near the rear of the cab. This requirement
shall not apply to airport tank trucks used exclusively to fuel aircraft.
(g) Exhaust system repairs
shall permit no leakage or discharge of exhaust gases at any location other than the discharge location required or permitted by this
section.
(h) The exhaust system shall be securely fastened to the vehicle.
(i) Exhaust systems may use hangers which permit required movement due to expansion and contraction caused by heat
of the exhaust and relative motion between engine and chassis of a vehicle.
(j) School Buses. The exhaust
pipe of each Type 1 school bus and each Type 2 school bus constructed on or after July 1, 1970, shall project beyond the rear or side of the body of
the bus but not beyond the bumper and shall not discharge near an entrance or exit, except that exhaust pipes may discharge near, but not directly
under, doors designed to be opened solely as emergency exits. No flexible pipe or tubing shall be used except where necessary to prevent
breakage.
