Driverless cars will be allowed on UK’s public roads from January 2015, the government has announced.
The UK’s government also invited cities to compete to host one of three trials of the tech, which would start at the same time.
In addition, ministers ordered a review of the UK’s road regulations to provide appropriate guidelines.
The Department for Transport had originally pledged to let self-driving cars be trialed on public roads by the end of 2013.
Business Secretary Vince Cable revealed the details of the new plan at a research facility belonging to Mira, an automotive engineering firm based in the Midlands.
“Today’s announcement will see driverless cars take to our streets in less than six months, putting us at the forefront of this transformational technology and opening up new opportunities for our economy and society,” he said.
UK engineers, including a group at the University of Oxford, have been experimenting with driverless cars. But, concerns about legal and insurance issues have so far restricted the machines to private roads.
Other countries have, however, been swifter to provide access to public routes.
The US States of California, Nevada and Florida have all approved tests of the vehicles. In California alone, Google’s driverless car has done more than 300,000 miles on the open road.
In 2013, Nissan carried out Japan’s first public road test of an autonomous vehicle on a highway.
In Europe, the Swedish city of Gothenburg has given Volvo permission to test 1,000 driverless cars – although that trial is not scheduled to occur until 2017.
UK cities wanting to host one of the trials have until the start of October to declare their interest.
The tests are then intended to run for between 18 to 36 months.
A £10 million ($16 million) fund has been created to cover their costs, with the sum to be divided between the three winners.
Meanwhile, civil servants have been given until the end of this year to publish a review of road regulations.
This will cover the need for self-drive vehicles to comply with safety and traffic laws, and involve changes to the Highway Code, which applies to England, Scotland and Wales.
Two area will be examined by the review: how the rules should apply to vehicles in which the driver can take back control at short notice, and how they should apply to vehicles in which there is no driver.
In May, Google unveiled plans to manufacture 100 self-driving vehicles.
The search-giant exhibited a prototype which has no steering wheel or pedals – just a stop-go button.
Google has also put its autonomous driving technology in cars built by other companies, including Toyota, Audi and Lexus.
Other major manufacturers, including BMW, Mercedes-Benz, Nissan and General Motors, are developing their own models.
Most recently, the Chinese search engine Baidu also declared an interest, saying its research labs were at an “early stage of development” on a driverless car project.
However, concerns about the safety of driverless cars have been raised by politicians in the US and elsewhere.
The FBI warned that driverless cars could be used as lethal weapons, predicting that the vehicles “will have a high impact on transforming what both law enforcement and its adversaries can operationally do with a car”.
