Under the proposals new cars would be fitted with cameras that could read road speed limit signs and automatically apply the brakes when this is exceeded.
Patrick McLoughlin, the Transport Secretary, is said to be opposed to the plans, which could also mean existing cars are sent to garages to be fitted with the speed limiters, preventing them from going over 70mph.
The new measures have been announced by the European Commission’s Mobility and Transport Department as a measure to reduce the 30,000 people who die on the roads in Europe every year.
A Government source told the Mail on Sunday Mr McLoughlin had instructed officials to block the move because they ‘violated’ motorists’ freedom. They said: “This has Big Brother written all over it and is exactly the sort of thing that gets people's backs up about Brussels.
“The Commission wanted his views ahead of plans to publish the proposals this autumn. He made it very clear what those views were.”
