Exhaust Pipes / Exhaust Silencers
A motor vehicle must be equipped with an efficient exhaust silencer, 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 not in efficient working order; or
- is so placed and maintained that exhaust gas or smoke leaks into the driving cab or passenger compartment of the vehicle.
