The charge of driving under the influence (DUI) is a common but potentially serious crime, both in the state of Missouri and across the United States. Whether you’re a longtime Missouri resident or just passing through, it’s important to understand the implications of this crime in case you’re ever found guilty of driving while influenced by alcohol or drugs. Here’s what you should know about how drivers are charged with this type of crime and what your rights entail.

What Happens at a DUI Checkpoint?

Police officers can pull vehicles over when they suspect the driver could be under the influence based on behaviors like swerving or driving below or above the speed limit. In addition, it’s possible for an officer to pull a driver over for another reason, such as having a taillight out, and then investigating for drug and alcohol use if they suspect intoxication.

Police officers may also use what’s known as a DUI checkpoint to check large volumes of traffic for signs of impairment. These checkpoints can be anywhere and usually take place when alcohol is most likely to be consumed, such as late in the evening and on weekends. Officers may check license plates and assess drivers for signs of drug or alcohol use, including slurred speech, lack of coordination, bloodshot eyes, and the smell of alcohol. If they suspect you’re intoxicated, you may be asked to complete a roadside sobriety or breathalyzer test.

What Are Your Rights?

In all states, any motorist who applies for a driver’s license gives consent to undergo field sobriety and chemical tests to check for impairment while operating a vehicle. This is what’s known as the “implied consent” law. While a police officer can’t physically force a motorist to take a breathalyzer or field sobriety test, failure to submit to testing can result in serious consequences like license suspension and other possible penalties.

In the state of Missouri, the blood alcohol concentration limit is 0.08%, meaning anything above that level can result in a DUI. An extremely high level of intoxication of 0.15% can result in an aggravated charge, which could carry a more serious offense. When you’re arrested for driving while impaired in Missouri, your license will be suspended for a period of 90 days if it’s your first offense. In some states, even first-time offenses carry a mandatory suspension of up to 24 months. However, vehicle confiscation, mandatory alcohol education and treatment, and the installation of an ignition interlock device—which requires the driver to blow into a tube to start their vehicle—may be required.
