What exactly does the term "eluding a police officer" mean?

Fleeing or eluding police occurs when a police officer gives you a visual or audible signal to stop, whether by hand, voice, emergency light or siren, and you do not obey. In Maryland, it is unlawful for a driver of a vehicle to disobey a police offer's signal to stop if (1) the officer is in uniform and his badge or similar sign of his authority is prominently displayed, or (2) the officer is in a marked police vehicle, regardless of whether is he is in uniform. Similarly, it is unlawful for a person who is neither driving nor in a vehicle to disobey such officer's order to stop, by fleeing on foot or by any other means. For a first offense, the penalty for eluding the police is a fine of not more than $1,000, or imprisonment for not more than 1 year, or both. If bodily injury results to any person during the offense, the penalty is a fine of not more than $5,000, or imprisonment for not more than 3 years, or both. If the offense results in the death of any person, the possible penalty increases to a term of imprisonment up to 10 years, and/or a fine. In addition, twelve points are assessed against the offender's driver's license for eluding or fleeing police.
