Can you plead to a lesser offense than DUI in Missouri?

A defendant might receive a "wet reckless," or a conviction of reckless driving involving alcohol, as a result of a plea bargain in which a charge of drunk driving is reduced to a case of reckless driving. There is no statutory provision on whether a wet reckless plea bargain will be accepted in Missouri, but it's possible a lawyer may be able to create a plea bargain for you.

Drinking and Driving Laws in Missouri

It is illegal in the State of Missouri to drive with a blood alcohol concentration (BAC) of .08 or above. The limit is lower for commercial drivers and drivers under the age of 21. In Missouri a DUI is a DWI, meaning "Driving While Intoxicated". The Missouri DWI law includes alcohol and/or drugs. While the DWI specify's a .08 BAC in the case of alcohol, it is illegal to drive with any amount of a controlled substance such as marijuana or cocaine present in the driver's blood.

How many drinks does it take to reach the legal limit? There isn't one right answer to this question. There are calculators and charts that can provide a reference based on certain criteria, however these devices shouldn't be used as the deciding factor when considering drinking and driving. In reality it takes very little alcohol to become legally drunk and physical characteristics such as weight, gender and body fat percentage can all be factors in the equation. The best answer is to have zero drinks before you drive.
