The police received several calls from worried motorists about the unnamed 85-year-old after he joined the busy road at junction 31 near Sheffield.
However, the fearless "driver" seemed totally chilled and completely oblivious to the 40-tonne lorries that were hurtling past him.
Trucker, Steve Saxon said: "I've been driving lorries since 1986 and I don't think I've ever seen anything so bizarre."
Eventually he was escorted safely off the motorway by a police biker and his family were contacted.
Andy Yorkshire, a mobility scooter trainer for South Yorkshire Police, added: "This man should thank his lucky stars he was stopped. He could have been killed."
