History of Drunk Driving laws The first jurisdiction in the United States of America to adopt laws against drunk driving was New York in 1910, with California and others following. Early laws simply prohibited driving while intoxicated, requiring proof of a state of intoxication with no specific definition of what level of inebriation qualified.[10] The first generally-accepted legal limit for blood alcohol concentration (BAC) was 0.15 (in 1938, the American Medical Association created a "Committee to Study Problems of Motor Vehicle Accidents"; at the same time, the National Safety Council set up a "Committee on Tests for Intoxication". Free Consultation In the US, most of the laws and penalties were greatly enhanced starting in the late 1970s, and through the 1990s, largely due to pressure from groups like Mothers Against Drunk Driving (MADD) and Students Against Driving Drunk (SADD) and leaders like Candy Lightner. Most significantly, zero tolerance laws were enacted which criminalized driving a vehicle with 0.01 or 0.02 BAC for drivers under 21. Free Consultation There are several situations in which the officer will come into contact with a driver, some examples are: Investigation The officer will typically approach the driver's window and ask some preliminary questions. During this phase of the stop the officer will note if they detect any of the following indicators of intoxication
If the officer observes enough to have a reasonable suspicion to legally justify a further detention and investigation, they will ask the driver to step out of the vehicle. Chemical test At the police station, the arrestee will be offered a chemical test of breath, blood or, much less frequently, urine. Breath test results are usually available immediately; urine and blood samples are sent to a lab for later analysis to determine the BAC or possible presence of drugs. If the arrestee refuses to submit to chemical testing, they will usually be booked for driving under the influence; there will be no evidence for filing the second charge of driving with .08% blood alcohol content. In some cases the arrestee may be charged with DWI even after passing a breathalyzer test if he or she refuses also to take subsequent urine or blood tests. However, the refusal will carry increased penalties on the driving under the influence charge (typically a longer license suspension and/or an increased jail sentence), and the act of refusing may be admissible in court as evidence of "consciousness of guilt". In some states, refusal to submit to a chemical test can result in an automatic suspension of driving privileges, regardless of whether the suspect is convicted of DUI. In an increasing number of jurisdictions, if the suspect refuses to take a chemical test the police in some states may restrain the individual and forcefully withdraw blood. This is particularly common in situations involving an accident with injury or death. In some jurisdictions this may require obtaining a warrant from a judge. Some commentators, such as Brown University's Jacob Appel, have criticized the role of medical personnel in this process. According to Appel, "If physicians acquiesce today in the removal of a resistant patient's blood, soon they may be called upon to pump the contents of an unwilling patient's stomach or even to perform involuntary surgery to retrieve an evidential bullet." Free Consultation While chemical tests are used to determine the driver's BAC, they do not determine the driver's level of impairment. However, state laws usually provide for a rebuttable legal presumption of intoxication at blood alcohol levels of .08 or higher (see blood alcohol test assumptions). Breath and urine tests can only estimate the BAC at the time the test is taken, which can be different than when the vehicle was actually operated.
