I have been asked by the owner, a friend, of a small garage who specialise in the above to review his RA programme. They had no RA in place for the above hazard. This is an activity they do 24/7 from small minor roads to motorways! I have looked into controls for this maintenance activity online, limited assistance though in what I could locate. I was wondering if anyone has direct experience of these controls they would share please.
For now I have suggested always park the repair vehicle behind the broken down vehicle minimum 100ft away (to act as a buffer), exit repair vehicle from kerb side only, hazard lights remain on , put large warning triangle another 100ft behind the repair vehicle. Wear clean hi viz jacket and trousers at all times.
I think a bank of flashing amber lights should also be attached to the rear of the repair vehicle and activated when a repair is in progress. Currently the repair guys operate from a van!

Appreciate any assistance

Thank you RP

Yes, good point, thank you Peter
