UK to allow driverless cars on public roads

30 July 2014 Last updated at 13:56 BST

The UK government will shortly outline measures to permit driverless cars to use public roads by next year.

Currently, autonomous vehicles are only allowed on private roads.

The Department for Transport had previously pledged to allow self-driving cars to be trialled on public roads by the end of 2013.
