Police are spotting motorists on the new A6 dual carriageway driving at "crazy speeds".
One driver was caught travelling at over 120mph on the new road - stretching from Drumahoe on the outskirts of Derry city and bypassing Dungiven - while another was clocked well in excess of 100mph.
A police spokesperson said those speeds "certainly got our attention".

The new dual carriageway opened in April following long delays influenced by the coronavirus pandemic and materials shortages.
With construction stretching four-and-a-half years, the road opening in April marked the end of the longest running road upgrade in Northern Ireland's history.
But the PSNI has warned drivers clocking up "crazy speeds" will find themselves before the court.
In a social media post, a spokesperson for police in Derry and Strabane said: "Road Policing Interceptors from Maydown are continuing to see some crazy speeds on the new A6 dual carriageway, Claudy.
"107mph and 124mph certainly got our attention and will also have the attention of the court."
The spokesperson added: "The faster the speed, the bigger the mess."
