If you suspect you're being pulled over by an unmarked car and are unsure it's a police officer, what should you DO?

• Stop immediately wherever you are, regardless of location
• Speed up and try to outrun the vehicle
• Slow down, and find a well-lit, populated location or a nearest police station to pull over, or call 911
  Explanation:

  "If you cannot identify an unmarked police vehicle and/or the driver as law enforcement, drive slowly and carefully below the speed limit and either (1) pull over at a well-lit, populated location, (2) drive carefully to the nearest police station and attempt to attract the attention of a uniformed officer or (3) call 9-1-1."
• Ignore the car and continue driving normally
