Seat Belt Installation Requirements

Seat Belt Installation Requirements
(Class 4A & 5A approved VTS only)

Vehicles, fitted with more than 8 passenger seats, used before 1 October 2001 may be subject to a seat belt installation check.

This can only be carried out by full Class 5 authorised test stations. It is essential therefore that you correctly identify vehicles that require a seat belt installation check.

A vehicle will require a seat belt installation check if;

• It has more than 8 passenger seats fitted (see note below) and that
• It has more than the legally required number of seat belts fitted (as per charts on pages 5 to 7 of Section 5.1) and that
• There is no proof that all the seat belt anchorage points have been type approved (see page 3) or
• There is no proof that a seat belt installation check has been previously carried out (this will be by a previous VT 20 being produced at time of test showing that the vehicle has had an installation check) or
• Extra seat belts have been fitted since a previous MOT installation check (Compare the number of seat belts now fitted with the number shown on the last MOT certificate).

Note: If it is obvious that the vehicle is capable of carrying more than 8 seated passengers (for example, by having wheelchair tracking/clamps fitted) the presenter of the vehicle should be asked how many passengers the vehicle carries in normal use to establish the seating capacity.



Information Method of Inspection Reason for Rejection
Installation check
1. Inspect the installation of each non-statutory seat belt mounting, referring to the guidance notes in this section AND the seat belt installation amplification note pack held at each class 5 Test Station, and diagrams to be found at the end of this section.

Note: This inspection can only be carried out by a vehicle test station authorised for classes 4A and 5A.

If you are aware that any of the following vehicles have had any seats/seat belts fitted by any other installer, e.g. where it has been adapted to carry wheelchairs and has removable seats on tracking, it will not be exempt and will require an installation check.
