MOT Test of Seat Belts including Supplementary Restraint Systems (SRS

    Seat Belts

    Test Description
    Most vehicles after 1965 must have seat belts. Irrespective of that requirement, all seat belts fitted to any vehicle must be inspected for:

    • Security of seat belt mountings and locking stalks
    • Security and operation of the locking/release mechanism
    • Condition of webbing
    • Retraction of the belt (it is allowed to manually feed it in)
    • A seat belt load limiter or pre-tensioner must not be missing or obviously deployed

    Notes: 1. For technical reasons the inertia locking mechanism is not checked. 2. On some vehicles the belt is attached to the seat, in which case the security of the seat to the vehicle would also constitute part of the seat belt check.

    Supplementary Restraint Systems

    This inspection includes airbags, seat belt pre-tensioners and seat belt load limiters.
