Derry City and Strabane Police have issued advice to motorists after their Neighbourhood Policing Team dealt with several issues at the weekend.
In the Waterside area, a number of vehicles were caught being driven without insurance or by an unaccompanied learner driver.
They also detected a scrambler being used in a local walking park.
The PSNI says, if you are using a motor vehicle on the road, you must ensure you have the correct licence and a policy of insurance in place.
They have also warned people that off-road scramblers should not be used in public parks.
