We all know that drinking and driving is not a good practice. First of all, it is very dangerous, and it is important to know the toughest and easiest DUI laws by state. Thousands of people die each year getting killed by alcohol intoxicated drivers, and there are even more badly wounded. Secondly, driving while intoxicated is illegal in all 50 States. This means that, even if you’re lucky to escape from driving while intoxicated incident without hurting yourself or others, it is likely to be accused of a crime. DUI Laws differ by State, so each State treats alcohol intoxicated drivers differently, some are toughest and some are easiest DUI laws by state. Sometimes it is called driving under the influence (DUI), driving while intoxicated (DWI), or under the influence (OUI). The links listed below are some general guidelines of DUI and other related crimes, as well as links to the DUI laws in each State.
Drunk Driving Laws 2015
November 2015
All states define driving with a blood alcohol concentration (BAC) at or above 0.08 percent as a crime, but the laws and penalties vary considerably from one state to another. 42 States, the District of Columbia, the Northern Mariana Islands and the Virgin Islands have administrative license suspension (ALS) on the first offense. ALS allows law enforcement to seize the driving license for a period of time if not a chemical test. Most of these states permit a limited driving privileges (such as work).
All states have some type of ignition interlock, in which judges require all or some convicted drunk drivers to install interlocks in their cars to analyze your breathing and turn off the engine if alcohol is detected. 20 States * (and the 4 counties of the State of California) have made contact the mandatory locks or strong incentive for all convicted drunk drivers, even criminals.
Federal law establishes that States adopt open container and repeat offender laws meeting specific requirements. Otherwise, a part of the State’s financing surface transportation is transferred to the State DOT or State Highway Safety Office. Alcohol exclusion laws allow insurance companies to deny payment for treatment of drunk drivers’ injuries, but they have limited doctors’ abilities to diagnose alcohol problems and recommend treatment. Some States have repealed such laws.
