INTRODUCTIONIn February 1992 Council Directive 62/6/EEC was issued which required certain categories of vehicle to be fitted with Road Speed Limiters. This was followed by Council Directive 92/24/EEC which set out, in the annex, the technical specifications for such limiters. These directives were then incorporated into UK legislation by amending Regulation 36 of the Road Vehicles (Construction & Use) Regulations 1986 by inserting sections 36A, 36B and 36C. (SI 3048/1993)In November 2002 the European Parliament and Council issued Directive 2002/85/EC which amended the original Directive 92/6/EEC to extend the range of vehicles to which the Directive applies. The Road Vehicles (Construction & Use) Regulations 1986 have now been amended (SI 2102/2004) to incorporate these new requirements which came into effect as of the 1st January 2005.From 1 January 2007 additional vehicles will now fall into scope under the speed limiter legislation introduced in January 2005. The changes affect all goods vehicles over 3.5 tonnes maximum gross weight and all passenger vehicles with 8 or more passenger seats, irrespective of weight. The relevant date for fitting speed limiters varies depending on the gross design weight of the vehicle, engine type (such as Euro III), international or national usage and the date of first registration.Specifically affected from January 2007 are goods vehicles between 3.5 and 7.5 tonnes and passenger vehicles with more than 8 seats, irrespective of weight, which were first registered between 1 October 2001 and 31 December 2004, have Euro III engines approved to Directive 88/77/EEC and are used on national operations in this country. In addition, goods vehicles first registered between 1 October 2001 and 31 December 2004 with a maximum gross weight between 7.5 tonnes and 12 tonnes, will have to have their existing speed limitation devices recalibrated from 60mph to 56mph.If a vehicle has, or is required to have, a speed limiter fitted and working, then it is not permitted to use the outside lane of a three or more lane motorway. If the vehicle is required to have a speed limiter fitted but it is not working, it will be illegal to use it on the public highway under the Road Vehicles (Construction and Use) Regulations 1986The new Speed limiter regulations apply to;passenger vehicles over 8 seats but not over 7500 kg Design Gross Vehicle Weight (DGVW)goods vehicles over 3500 kg but not over 7500 kg DGVWThe regulations are applied depending on vehicle age as follows:1. Vehicles first used prior to 1 October 2001 - No requirement.2. Vehicles first used on or after 1 October 2001 up to and including 31 December 2004 - For British domestic use only will require a speed limiter set such that the vehicle speed cannot exceed:100 kph (passenger vehicles) (62.14 mph) or90 kph (goods vehicles) (56 mph)The above were required to be fitted by 1 January 2007 if they had a Euro 3 engine with emissions approval under directive 88/77/EC.EURO 2All vehicles with Euro 2 engines are not subject to the requirements. In addition the following vehicle types DO NOT need a speed limiter as they do not have engines approved under the relevant directive, and include:Any petrol engine or petrol engine converted to run on LPGCitroen Relay 2.0 litre and 2.2 litre HDi enginesFiat Ducato with 2.0 engines (engine code RHV)Ford Transit (all)Iveco Cargo all, except vehicles with engine code F4AE---.Iveco Daily all, except vehicles with engine codes F1AE---, F1CE---, 8140.43B, 8140.43N and 8140.43S with PIC code 'G.' (The PIC code is found on the ID plate on the Shut panel for the bonnet identified by the 3rd character.)LDV (all)Mitsubishi Canter with 'R' as the 12th VIN characterNissan Interstar all except vehicles with engine codes ZD3-A202, G9U-A754, S9W-A702 & G9U-A724. All Primastar.Peugeot Boxer 2.0 litre and 2.2 litre HDi enginesRenault Master all except vehicles with engine codes ZD3-A202, G9U-A754, S9W-A702 & G9U-A724. All TraficVauxhall/Opel Movano with E,F,G,J,K,L,M,N,P,T or W as 7th VIN characterVauxhall/Opel Vivaro (all)Volkswagen (all except 2.5lt/2.8lt 109bhp/158bhp engine codes AVR & AUH respectively.)Other makes may similarly not be subject to the requirement for a speed limiter include, Vehicles first used on or after 1 January 2005: For British domestic use only these will require a speed limiter set such that the vehicle speed cannot exceed;100 kph (passenger vehicles) (62.14mph) or90 kph (goods vehicles) (56 mph) by 1 January 2008If used internationally then speed limiters set to this speed were required from 1 January 2005. The exemption list of engine types above does not apply to these newer vehicles.ANNUAL TESTSpeed Limiters are tested as part of the Annual MOT Test (plating) on HGV vehicles.REASONS FOR FAILURE1.

Set speed marked on Speed Limiter Plate greater than:•a. 90 km/h (56 mph) for a relevant goods vehicle.•b. 100km/h (62.14 mph) for a relevant bus/coach.3. Response speed of•a. More than 92 km/h for a vehicle described in paragraph A in the application section,Or•b. More than 107 km/h for a vehicle described in paragraph B in the application section.4. Speed Limiter:•a. Not fitted.•b. Insecure.•c. Actuating rods/cables disconnected or damaged so that the operation is obviously affected.•d. Wiring disconnected or can easily be disconnected by unauthorised means.•e.
