The project reviewed the literature related to the methods and technologies for detecting and testing for drugs in drivers. In addition to providing a general overview of the impaired driving detection, assessment, testing, and adjudication processes, the documentation included the specific contributions that the law enforcement officers and toxicologists make to this often convoluted process. The process flows were detailed in order to provide the reader with an appreciation of the complexities related to processing the drug impaired driver as well as providing a framework from which the reader can consume the literature review related to difference between the detection of presence and impairment. The report provided information that can be used as a tool to positively impact the problem of impaired driving and save lives.
