These photographs show some of the first occasions that York police have exercised their new powers.
Shared by NYP York City on Twitter, the pictures show vehicle checkpoints.
Drivers were asked to stop and account for their journeys on Blossom Street and Castle Mills Bridge, among other locations.
Earlier today North Yorkshire Police said they would begin to stop cars to check where people were going.
The measures are to enforce the lockdown and stop the spread of coronavirus.
And if you don’t comply new powers mean you could be fined, be arrested and end up in court.
The message, York police tweeted, was clear: “North Yorkshire Police stopping vehicles to ensure motorists are complying with the restrictions and only making essential journeys. #StayHomeSaveLives”
