Blue Light Special

Quick! You’re driving down the street in Virginia and you see flashing blue lights in the rear-view mirror. What is it?

That’s right. It’s a police officer. From the lights alone, you can’t tell if it’s a state trooper, a sheriff’s deputy, or a local police officer, but you know that it’s a police officer. That’s because in Virginia, only police cars are allowed to use blue flashing lights. Fire trucks and ambulances can use red and white flashing lights, but not blue.

Here in England, police cars, fire trucks, and ambulances all use flashing blue lights.

(That’s it. Just a random observation. Nothing insightful here.)
