New gates have been installed on the Somerset Levels to allow roads to be closed and prevent motorists from driving down flooded roads.
The gates, which can be locked, will be used instead of road closed signs to stop drivers from getting stranded.
Councillor John Osman said during the floods of 2014 many were stranded after ignoring the warning signs.
He said the gates had been suggested by residents as such a simple idea but one which could make a real difference.

Mr Osman said during the 2014 flooding there were numerous reports of vehicles becoming stranded after ignoring road closed signs.
"The new gates will make this impossible and should reduce the burden on our emergency services at times when they are likely to be stretched."
The gates can be operated by Somerset County Council or the emergency services based on flood information provided by the Environment Agency.
When gates are closed, key services along with some local residents and landowners will be provided with the combination to allow essential access.
