Local authorities will have the right to set out road signs without Government approval under new plans, transport minister Norman Baker has announced.
Speaking to the Lib Dem conference in Birmingham, Mr Baker said handing powers to councils would cut "pointless form-filling" and help cut the amount of redundant signs on Britain's roads.
The proposals, to be set out in Parliament next month, will mean councils will have control over 20mph speed limit signs, as well as those barring entry for cyclists and highlighting parking bays.
Interactive signs will be introduced to advise drivers on alternative routes during periods of high traffic congestion, Mr Baker said, which could help reduce the likelihood of people needing to use theirbreakdown cover.
There will also be more signs to help pedestrians and promote greater road safety for cyclists.
He told delegates: "There are still lots of signs around warning of cattle farming where cattle farming no longer occurs and so-called temporary signs advising of events long past.
"In carefully selected locations, signs will be erected to advise motorists of alternative ways from getting from A to B. This will help cut carbon and ease congestion on our roads."
