A third DWI and your driver’s license
Aside from the criminal penalties, a third DWI conviction will cause a two-year suspension of your driver’s license. You may be able to get your driving privileges reinstated before then, but you will have to pay to install an ignition interlock device into your vehicle. This device requires you to blow into it before you can start your engine, so it can measure if you have any alcohol in your system. Ignition interlocks are expensive to install and maintain.
Your best chance of staying out of prison
Hopefully, you will never have to face drunk driving charges for a third time. But if it does happen, the prospect of going to prison for several years can be scary. Working with a defense attorney gives you the best chance of maintaining your freedom.
