China has conducted its first test of a Transit Elevated Bus (TEB), which hovers above traffic.
It took to the streets in Qinhuangdao, north China on Tuesday.
The 22-metre long vehicle can carry up to 300 passengers.
The passenger compartment rises above other vehicles on the road, allowing cars to pass underneath.
The concept is designed to help ease some of the country's massive traffic problems.
The TEB is powered by electricity, meaning the system could also help cut down on air pollution.
China's official news agency Xinhua says the TEB has already attracted interest from governments in Brazil, France, India and Indonesia.
