Will getting a ticket for parking in a handicap violate my probation?

It depends on the terms of your probation. When you were placed on probation, the court should have told you all the rules you need to comply with as part of your probation. Frequently, the probation order will state do not violate any laws. It will sometimes state, "with the exception of minor traffic infractions". You will want to look at the probation order in your case to see what language was used. Most likely, this will not be a basis for revoking your probation. If you had an attorney on your probation case, you should contact that attorney for more specific advice.
