If a job application asks, "Have you ever pled guilty been convicted, entered a plea of no contest or had prosecution deferred for any crime" do I list a speed ticket?

Crimes are misdemeanors and felonies. Most traffic infractions, including speeding, are violations, which are a lesser category of offense and are not typically considered crimes. Unless the speeding ticket to which you are referring is so serious as to constitute a misdeanor or felony, which is very unlikely, you would not need to list it. I believe that in IL, for example, only if you exceed the speed limit by at least 40 mph would it be considered a misdemeanor or crime.
