Reasons given for H&S rules

I once went on my motorcycle to visit a London Buses garage on my motorbike, which I parked well out of the way before walking to the building.

On my way out, I was told that I would have to be helped across the road to my bike because buses “sometimes came in and out of the garage.”

Wow…if I couldn’t cope with that how would I survive riding my motorbike on the North Circ?
