Road tests have been carried out in China for a huge bus that aims to drive over traffic congestion.
The bus is raised well above the height of standard vehicles and therefore can travel over them when there are traffic jams.
The road test at 10km per hour on a test track examined the breaking system, drag and power consumption.
Called the Transit Elevated Bus (TEB), the vehicle is 22m long, 7.8m wide and 4.8m high and can carry 300 passengers.
