I don't think a good attorney is going to have a "one size fits all" fee that will answer your question.
However, most attorneys will ask you a few questions about the case and then quote you a fixed fee over the phone. If your case is in Fairfax, please give us a call and we will tell you a fee dependent upon the facts of your case.
Most reputable attorneys would charge anywhere between 3 and 8 hundred bucks for a reckless driving charge. Some less, some more. There is no standard fee. It depends on your circumstances, the court and the attorney.
