Abu Dhabi Police will introduce a new speed limit on a main road in the capital from Monday.
The force tweeted the news on Saturday, explaining that a section of the Sheikh Zayed Road would now have a reduced speed limit of 100 kilometres an hour from 120kph.
The new limit applies to the Qasr Al Bahr intersection in both directions, it said.
The road is one of the main routes into the capital from the outer suburbs and Dubai.
Speed cameras have been calibrated to capture anything travelling at more than the new limit from September 26.
Abu Dhabi Police frequently advise motorists on safer driving habits and often reduce speed limits during difficult driving weather.
