Very good, I went down the M1 3 days after it opened with my Dad in a brand new 1959 2 stroke Commer with 5 Rootes Group cars loaded for London Victoria Docks.
I had forgotten about those early fog warning lights.
i love watchin them old transport films
Enjoyed watching those and not a hard hat or hi vis to be seen
