EXHAUST SILENCERS / EXHAUST PIPES
A motor vehicle must be equipped with an efficient exhaust silencer system, which must;
• allow the exhaust gas from the engine to be projected through such silencer;
• not emit exhaust gas or smoke from the engine which is so dense as to cause a nuisance to, or obstruct the vision of other road users, or
• be in such a position that oil or other flammable liquid or material cannot drip or fall onto it,
• be so maintained that exhaust gas or smoke does not leak into the driving cab or passenger compartment of the vehicle.
A motor vehicle may not be used on a public road-
• without an efficient exhaust silencer.
• unless the gas from the engine is projected through such silencer
• if the exhaust gas or smoke from the engine is so dense as to cause a nuisance to, or obstruct the vision of other road users, or
• if the exhaust pipe or silencer thereof is in such a position that oil or other flammable liquid or material can drip or fall onto it, or
is so placed and maintained that exhaust gas or smoke leaks into the driving cab or passenger compartment of the vehicle.
