It's a simple fact: drinking and driving kills people. Driving after drinking alcohol is known as Driving Under the Influence (DUI) or Driving While Intoxicated (DWI).
All 50 states have now set .08% Blood Alcohol Concentration (BAC) as the legal limit for Driving Under the Influence, according to the Insurance Institute for Highway Safety (IIHS). For commercial drivers, a BAC of .04% can result in a DUI conviction nationwide. For those under 21, there is a zero tolerance limit; any amount of alcohol is grounds for a DUI arrest.
A DUI arrest can lead to expensive consequences, including spending time in jail, having your driver's license suspended or taken away and fines. If you hit or kill someone while you are driving impaired, the consequences are even worse.
It's also illegal to have an open container of alcohol in your car. If you're transporting alcoholic beverages, they should be sealed and in the trunk.
In some cities, law enforcement officials set up sobriety checkpoints along the road to deter and identify impaired drivers. Checkpoints are typically set up during holiday weekends or on dates when there might be an increase in drinking and driving. If you're stopped at a checkpoint, you'll be asked several questions and might be asked to perform a sobriety test (like saying the ABC's backwards, performing some physical movements or breathing into an alcohol sensor). If these tests show that you have high alcohol levels, the police may arrest you.
