Part 7—Control of emissions and LPG fuel systems
Note: This Part sets out requirements to ensure that motor vehicles do not put out too much smoke or noise, and that exhaust gases cannot enter the passenger compartment of a vehicle. It also deals with rules to ensure that LPG fuel systems are safely installed in vehicles, and that vehicles with LPG installed can be identified.

7.1  Crank case gases

7.2  Visible emissions

 (b) not pass through the passenger or driving compartment; and
 (c) if the vehicle is fitted with an exhaust system with a vertical outlet pipe that does not direct the main exhaust flow straight up—direct the flow rearwards at an angle within 0° to 45° of the longitudinal centre line of the vehicle; and
 (d) if a rain cap is fitted—be installed so that the hinge of the cap makes an angle of 90° (plus or minus 10°) with the longitudinal centre line of the vehicle when
