Driving under the influence (sometimes known as driving while intoxicated/DWI or operating under the influence/OUI) can have serious legal ramifications, from the loss of your driver's license to jail time, fines and increased insurance rates. If you have a commercial driver's license, the penalties can be even more serious. If you've been charged with drunk driving, talk to a criminal defense attorney immediately. A lawyer with DUI defense experience can review the police report, breathalyzer results and other evidence, try to find weaknesses in the prosecutor's case and work tirelessly in your defense. DUI law firms can also work with clients and prosecutors on plea bargains, alternative sentences and license reinstatements.
