A cut-and-shut minivan was seen driving along a road with a trailer replacing the rear wheels.
The metal frame had been welded onto the back of the mud-covered Hyundai people carrier in Phnom Penh, Cambodia.
A shocked motorcycle rider noticed the dangerous vehicle on June 20.
They said: ''The trailer was rusty and looked like it could break. If it snapped then the van would surely crash.''
Cut-and-shut cars are made by welding together to two old vehicles to make a new one.
