People travelling in and out of Mosgiel in their cars on Saturday morning could do so only after being questioned by police.
Traffic came to a halt on Quarry Rd, State Highway 87, as police pulled vehicles over, ensuring drivers were complying with the Government's Covid-19 alert level four restrictions.
A police spokeswoman said the first step was to educate.
“Our goal is to ensure people understand the importance of staying home.”

She said people would be told how to stay safe but if they continued to break the rules, it would be at the police officer’s discretion to give them a warning, or if needed, arrest them.
Police would continue to be visible within communities and have conversations with people who left their homes.
“Stay at home, save lives.
“It is that simple,” she said.
