The UK government needs to take action to figure out how driveless cars would work on the country's roads, an influential group of MPs has said.

The Commons transport committee says the government must evaluate how liability for crashes would be decided, how drivers would be trained and licensed and it called for greater re-assurance about people's safety.

The Department for Transport (DfT) said the public's safety was "first priority" and added that it was working closely with the industry.

Evidence heard by the committee suggests that within 10 years UK roads will have on them full automatic, semi-automatic and manual cars.

Committee chair and Labour MP Louise Ellman told the BBC that there needs to be a decision on who would be responsible in the event of a driverless car crash.

"Who is liable? Is it the manufacturer of the vehicle, or the technology in it? Is it the driver?" she said.

Ms Ellman said the businesses would be given tax incentives to prevent the UK lagging behind the likes of US, Germany, China and Japan.

A DfT spokesman said: "Public safety is our first priority as we adapt to advances in motoring technology.

"We have a comprehensive approach to ensure the UK is at the cutting edge of developments."

AA president Edmund King said: "The report rightly points to potential problems of a transition period on the roads.

"There is a potential nightmare scenario whereby robotic driverless cars are fighting for space with cars with humans behind the wheel and indeed semi-autonomous cars with no-one totally in control.

"We really need a safe vision for the future whereby all vehicles and all road users can coexist in harmony.

"This vision will entail government, manufacturers, insurers and indeed drivers agreeing the way ahead."
