Most Washington State criminal defense attorneys already understand that there is a cure to insomnia, and it is found on this very page. DUI laws and statutes are necessary reading for any DUI defense lawyer and for those whose sleep is negatively affected. The difference between a good defense attorney and a great defense attorney often is found in their understanding of DUI laws, statutes and case law. The following are the primary DUI statutes that will be used against a defendant charged with DUI and potentially, used as a defense to driving under the influence in Whatcom County, Skagit County, Island County and Snohomish County.
