If a police officer makes a lawful stop

Got that from here, knew it didn't sound right, but left it in anyway.

RS Ronald A. Steinberg Partner at Law Offices of Ronald A. Steinberg and Associates... Usually a traffic case is considered a misdemeanor, like jay-walking, or spitting on the sidewalk. If a police officer makes a lawful stop, that is considered an arrest. The issuance of a ticket is the court's exercising its jurisdiction over you. usually, an arrest for a traffic offense is of no importance in terms of your "criminal" history.
