So basically i was with my mum on the way to college, we were about to go to bridge to hawally and there was police car parked beside it and the police man being out with his phone, then i noticed he seem to point his phone toward us and did a sign that indicates that we should pull over.
We did and the police asked my mum for her license, she gave it to him, he then seems like he took a picture of it and then gave it back, then he let us go, we were confused as to what happened, my mum is also pretty worried that we might've violated a rule or something.
Is there any reason why the police pulled us over?
