Police in Co Down said they have received reports of young drivers doing "doughnuts" on the road.
They also said they have been made aware of "vehicles gathering and dangerous driving" on the Old Dublin Road in Newry.
In an appeal to "young drivers to act responsibly when in control of a car" they have also warned that they could receive fines "or worse".
"Please consider the negative impact that this type of activity can have on the local community," said a Police Newry, Mourne and Down spokesperson.
"Those who engage in these activities may regard them as ‘fun’, but this is not shared by the people who have to endure this type of selfish behaviour.
"Driving on the public road brings with it certain responsibilities: to the drivers and passengers; to their families and friends; and to the community as a whole.
"These responsibilities should not be taken lightly. It is important to point out that drivers should expect to receive a fine or worse, prosecution through the courts, should they be detected engaging in careless or dangerous driving or modifying their vehicle illegally.
"We are currently working to address the problem but would urge anyone who knows of dangerous driving in their area to note down the registration details of the offending vehicles and contact police immediately."
