Highway Code rules are set change again as ministers plan another update.
Motorists already struggling to get their heads around last month's changes will soon face yet another.
The new rules are expected to come into force later this year in a bid to alter advice for driverless cars, reports The Mirror.
The UK's Transport Secretary Grant Shapps is hoping that the UK will be the first nation to get autonomous vehicles on the roads.
However, politicians and motoring organisations are worried that the constant updates to the Code will leave drivers confused and leave roads more dangerous.
Experts also fear that the second update will pose risks to life.
The AA’s Jack Cousens said: “It’s frustrating. As soon as they update it something else comes along.”
Shadow roads minister Gill Furniss said: “This shambolic government are so mired in scandal they can’t even get the basics right. They haven’t even bothered to publicise the last set of major changes to rules on the road before they announce the next set.”
Tory peer Anne McIntosh added: “Would it not have been a good idea to present all the changes in one go?”
And Simon Williams of the RAC said: “It’s vital the changes are crystal clear, otherwise there’s a very real risk drivers will be confused. This could lead to avoidable road traffic collisions.”
The new rules will tell drivers when they can take their hands off the wheel in traffic jams so their cars can nudge forward automatically.
It will be the first function driverless cars will be allowed to perform when so-called ALKS – Automated Lane Keeping Systems – are introduced later this year.
Mr Cousens added: “You won’t be able to have a nap or pick up a newspaper because you must always be ready to take charge of the vehicle again.”
Ministers say driverless vehicles could be worth £42billion to the British economy by 2035 and create 38,000 new jobs.
There was widespread confusion over last month’s Code changes giving new rights of way for cyclists and pedestrians.
And a section on banning hand-held mobile phones even while stationary was forgotten and only added on Thursday.
Roads minister Baroness Vere said: “Further changes covering the use of self-driving vehicles are planned and will be laid before Parliament later this year.”
Ministers say driverless vehicles could be worth £42billion to the British economy by 2035 creating 38,000 new jobs by cornering six per cent of the world market.
A DfT spokesperson said: “The development of self-driving vehicles has the potential to revolutionise travel, making every day journeys easier and greener – and crucially, safer.
“These changes will set clear expectations for road users and drivers.”
