Traffic ticket laws are made on a state by state level, so the rules that apply to any given situation will be dictated by where you live. In every state, though, it is possible for your license to be suspended as a result of unpaid traffic tickets. When you are issued a traffic ticket, you must show up in court or otherwise respond to that ticket. Generally, you have three options when the ticket is issued: send in the money to pay your fine (which amounts to pleading guilty and which can result in points on your license), try to arrange a plea deal (this may involve pleading guilty and arranging to take a defense driving class in lieu of having points awarded on your license), or try to defend yourself. You must do one of these things, and if you just ignore the ticket, a number of consequences may occur, including a suspended license.
If your license is suspended as a result of not coming to court for your traffic tickets or not paying for them, you can get your license back. However, to do so, you are going to have to pay the tickets that you owe the money on. Generally, if you didn't show up in court the first time, you won't be allowed to plead guilty or arrange a deal any more. You will just have to pay. If you are unable to do so, you may be able to arrange to do community service instead of paying or you may be able to arrange a payment plan, but one way or the other, you must resolve the underlying problem.
Once you have resolved the issue of the unpaid traffic tickets, you next have to actually take the steps to get your license back. Normally this means petitioning the court that suspended your license in the first place. You will also have to pay additional fees at this point, including civil penalties for the nonpayment of your initial tickets, and fees for reinstating your license.
This all gets very expensive quickly and it is going to cost you to get your license back. The better option is to hire a traffic lawyer and deal with your tickets proactively in the first place. If it is too late to do this, then you should strongly consider hiring an attorney to help you figure out the best way to deal with the traffic tickets and get your license back with minimal cost to you.
