How fast can a police officer go with lights on?

Answer:
Depends on the department they work for. Some departments, such as Dallas TX, only allows their officers to drive 20MPH above the posted speed limit.

Other departments my allow their officers to drive as fast as they want while responding to an emergency with their lights and siren on.
