On social media, police said: "We stopped this vehicle at Snainton after noticing that it appeared to be a bit heavy. Having escorted it to a weighbridge, we found that the towing vehicle was a staggering 3,560kg or 101% overweight.
"The total combination, vehicle and trailer, was 2,840kg (40%) overweight. To make it worse, an important safety feature, a secondary coupling, was not fitted.
"The vehicle was prohibited from being driven until the load was removed. The driver and company will be reported to court where they can expect a significant fine if convicted."
