This
inspection applies to all vehicles which are required to be fitted with a Speed
Limiter.
Vehicles requiring a speed limiter
Vehicles required to be fitted with a speed limiter are: Vehicles with more
than 8 passenger seats
• a maximum speed in excess of 100km/h (62.14mph), if a speed limiter were
not fitted, and
• with a DGW not exceeding 7500kg and first used on or after 1 January 2005,
or
• with a DGW exceeding 7500kg and first used on or after 1 January 1988
Vehicles with more than 16 passenger seats
• with a maximum speed in excess of 112.65km/h (70mph), if a speed limiter
were not fitted, and
• with a DGW exceeding 7500kg, and
• first used between 1 April 1974 and 31 December 1987 and
Note: Vehicles with a DGW not exceeding 7500kg with Euro III (or later)
engines, first used between 1 October 2001 and 31 December 2004 are required to
be fitted with a speed limiter. Specific identification of these vehicles is not
required; however, if it is obvious that a speed limiter is fitted then it must
meet the requirements of this inspection.
Modified vehicles
Some vehicles may have been modified by, for example, changing the rear axle
ratio and will no longer be capable of exceeding 100km/h.
If a vehicle presenter claims that this is the case, he must produce a signed
declaration stating the specific reason (e.g. low ratio axle fitted) why the vehicle
is no longer capable of 100km/h.
Note: Speed limiters wired through ‘ignition switches’ are acceptable but any
other devices that could enable the speed limiter to be switched off while driving
are not.
Tamperproof Devices
Mechanical and electrical connections that require the use of special tools,
normally only available from vehicle/component manufacturers for disconnection
or adjustment purposes, are acceptable instead of the tamperproof devices referred
to in MoI 6. Modern tamperproof devices are electronic and therefore not possible
to check.
Determining Design Gross Weight
The DGW should be taken from the manufacturer’s plate. For vehicles first
used before 1 April 1982 not fitted with a manufacturer’s plate, multiply the
maximum number of passengers and crew, excluding the driver, by 63.5kg and add
the kerb or unladen weight displayed on the side of the vehicle to obtain the
calculated laden weight, which should be used instead

1. Check that a
speed limiter plate is securely fixed in the driver’s compartment in a conspicuous
position.
Note: If the plate is fixed to the driver’s compartment window it is acceptable
for the details to face inwards or outwards, provided that exterior facing plates
can be read by a person of average height.
2. Check that the plate is clearly and indelibly marked with the speed at which
the speed limiter has been set (the speed may be shown in mph or km/h)
Note: The character and composition of the plate and size of lettering
are not important provided the details are legible.
Speed limiter
This inspection is confined to those parts that are readily visible without dismantling.
3. Check that a speed limiter is fitted and secure.
4. Check any exposed actuating rods/cables for disconnection or damage.
5. Check any visible electrical wiring that energises the speed limiter for disconnection
or potential easy disconnection by unauthorised means.
6. Check as far as possible the presence and condition of tamper- proof devices
such as seals, lock nuts, pins, wires, plastic inserts, sealing compound or sealing
paint on mechanical and electrical connections.

1. A speed limiter
plate
a. Missing or insecure.
b. not in a conspicuous position
2. A speed limiter plate
a. Not clearly and indelibly marked with the set speed.
b. shows a set speed greater than that permitted (see information column)
Speed limiter
3. A speed limiter not fitted or insecure.
4. Actuating rods/cables disconnected or damaged to the extent that the operation
of the speed limiter is obviously affected.
5. Electrical wiring is obviously disconnected or can be easily disconnected by
unauthorised means.
6. Tamperproof device missing or defective, or showing evidence of obvious disturbance.
