The new edition of Maintaining Roadworthiness has just been published. This now contains a “recommendation” from VoSA that vehicles and trailers which are 12 years old or more should now be subject to a Safety Inspection at least every 6 weeks. There is further “advice” about the number of brake test reports “expected” between MOTs.
Before I retired I carried out weekly “brake tests” between the Cat & Fiddle pub and Macclesfield.

When I drove a 1418 merc that route was also a very good sphincter test.
