Petra tapped her fingers idly against the steering wheel as she drove, scanning the empty streets. The worst of the weekend rush was over this late into the night and she didn't expect much more than the occasional drunk straggler. Which weren't any of her business unless they decided to vandalize public property or needed help.

The police cruiser turned the corner and Petra had just about decided to stop by somewhere to get a coffee when she spotted a lone car blowing through the intersection. It cut her off, nearly clipping her bumper, and took off down the street with squealing tires.

So much for a quiet patrol, Petra thought and pushed her foot down on the gas to follow. Now who are you? Intoxicated, in need of help, or just reckless?

She kept a careful eye on the car as she shadowed it, trying to discern more about the driver - or drivers. From what she could tell in the dark, there seemed to be only one person in the car.

One person operating the vehicle, possibly intoxicated. Excessive speed. Driving seems unsteady. she catalogued mentally.

Before the speeding car could pull onto the highway, Petra flicked a button on the cruiser's dashboard, a short howl of the siren disturbing the quiet of the night. She watched the car slow and pull over, coming to a stop at the side of the road.

Smart choice.

Putting the police cruiser into park, she climbed out and approached the other car's drivers side. She rapped one knuckle against the window.

"Good evening, ma'am," she greeted the woman behind the wheel once the window had rolled down. "I'm gonna need you to step out of the vehicle."
