According to VA law, reckless driving is not a speeding ticket, it is a class 3 misdemeanor punishable by a possibly hefty fine, up to a year in jail, and loss of license. I don't recall the exact max fine, but it was decent. Pretty rare that you would get maxed out unless you go into court and literally dare the judge to do it. Cool thing about VA is if you do get jail time, they typically let you serve it on weekends, i.e., surrender yourself on Friday and go home Sunday, and the weekend days count 2 for 1 (don't ask me why). So yes, even though he didn't arrest you right then, there is a possibility you could end up in jail.
I had one back in 05, doing 84 in a 45. Showed up to court by myself, and the judge gave me a funny look. 'Where's your attorney?' I blinked and said, 'I didn't think I needed one for a speeding ticket.' 'Well, considering you are charged with reckless driving, a class 3 misdemeanor punishable by (insert info from above here), would you like a continuance until a later date so you can get one?'
Got an attorney, pretty sure I paid more than $400, and he was a total shyster. Sent me to a specific shop to get my speedo calibrated, insisting I ask for Bob. "Make sure you ask for Bob, and tell him I sent you." So I went, paid the fee to have it checked, and the guy basically asked me how far off I wanted him to write the speedo. It was an 04.5 Jetta GLI, in early spring of 05, so there was absolutely nothing wrong with it and I wasn't going to falsify - wouldn't have made much difference anyway. Attorney tried to make me go back and get it redone, but I told him to stuff it.
Long story short(er), ended up with $125 fine plus court fees, so just under $200. Plus the attorney, so way too much but still better than jail time.
