The engine was road-tested in light lorries, but nothing seems to have been heard of it after 1937.

SA-110 was a light lorry prototype which was only produced six units.

The Bradford was also manufactured as a light lorry, as would later be described as a pickup truck.

Designed as an early attempt at a roll on - roll off cart and later car and light lorry transport vehicle.

Most passenger cars would eventually be required to run at 39 miles per gallon, and light lorries at 30 miles per gallon.

The new charges were blamed for driving heavier steam traction off the road in favour of the lighter lorries powered by internal combustion engines using imported oil.

Sentinel, along with Foden, dominated the steam market, but the 1930s saw the demise of both companies' ranges as new legislation forced the development of lighter lorries, Sentinel surviving the longest.

Conceived as a light lorry the SD Freighter soon proved to be popular for refuse collection with its low loading height, small turning circle and simple control utilising two handles, known as "Tillers".

Extensive Community legislation is already in place or about to come into force (fitting of speed governors in light lorries, stricter and reliable monitoring of road haulage with the aid of electronic tachographs, general requirement to wear seatbelts in coaches and measures to make tunnels safer).
