Driving while suspended ("DWS") and driving while revoked tickets are very serious tickets and can result in jail time. If you plead guilty to a DWS ticket, your license will mostly likely be suspended for an even longer period. A DWS ticket in Missouri is 12 points and if you plead guilty to one you will be suspended for one year immediately. You may also be suspended in Kansas and you run the risk of being found a Habitual driver and losing your license for 3 years.
I think it is absolutely necessary to hire an attorney if you have a DWS ticket. The most important thing for you to do when you get a DWS ticket is got get reinstated as soon as possible. You can find out why you are suspended by contacting the Missouri Department of Revenue or Kansas Driver Control. These agencies will tell you why you are suspended and what you need to do to get reinstated.
The most common basis for a suspension is failure to appear charges. This occurs when you ignore a traffic ticket. The best way to take care of these FTA charges is to either pay your ticket or hire an attorney to deal with it for you. Once the ticket is taken care of, be sure to get a "compliance notice" so you can send it your home state license bureau.
If you have a DWS ticket, hiring a lawyer means you will most likely avoid the 12 points you risk in Missouri and you avoid the possibility of being declared a Habitual driver in Kansas. If you have been reinstated, an attorney can get the charge against your reduced significantly in most jurisdictions.
