Yes, you can be arrested for not stopping when the vehicle performing the stop is a marked law enforcement vehicle. Refusing to stop for a police vehicle that has its emergency lights and siren activated is considered a criminal act, sometimes charged as misdemeanor eluding police or even a felony depending on the circumstances. The law requires that you stop immediately when signaled by a marked police vehicle, and failure to do so can lead to arrest, fines, and imprisonment. Police officers in marked vehicles have distinct identification such as flashing red lights, sirens, and uniforms, and these are part of the legal basis for requiring motorists to comply with their stop orders.
