What Happens During a Missouri DWI Arrest?
Driving after drug or alcohol consumption can result in charges for driving while intoxicated (DWI), regardless of how far you had to drive or whether your designated driver left you behind. If there is reasonable suspicion of drunk driving, such as erratically, law enforcement officers will pull you over for probable cause.
A police officer may take the driver to jail for failing a portable breath test or field sobriety test. Field sobriety tests must be conducted according to strict procedures to be admissible in court as evidence.
Lawyers in Kansas City may be able to help you if you have been arrested for DWI in Missouri. An experienced lawyer can challenge the results of the breath or field sobriety tests in court and the procedures used by law enforcement to conduct them.
Mouth Alcohol in Breath Tests
Breathalyzer test results can be affected by mouth alcohol, even if there are trace amounts of alcohol in the mouth. It occurs when a small amount of alcohol remains in the mouth or throat, contaminating your breath as it passes through the breathalyzer.
DUI breath tests will detect this alcohol before it is absorbed into the bloodstream, producing a falsely high BAC reading, which can lead to innocent people being charged with DUI.
Several products contain alcohol, including:
In rare DWI cases, elevated blood alcohol levels can also be caused by medical conditions such as gastroesophageal reflux disease (GERD) or acid reflux. Usually, this occurs after drinking alcohol.
It is important to note that an officer may require you to stay in a certain position or remain stationary during observation. Any evidence they collect may be thrown out of court if they do not follow these procedures.
If you have been arrested for DWI in Missouri and believe police observation procedures were not followed, contact a knowledgeable DWI lawyer. They may be able to help you understand your rights and build the best defense possible for your case.
Mouth Alcohol as a DWI Defense
Kansas City DWI lawyers can raise a mouth alcohol defense when:
A law enforcement officer did not wait 15 minutes before conducting the test or waived the 15-minute observation period altogether.
During those 15 minutes, the officer didn’t continuously watch the driver.
GERD or other digestive issues may have caused mouth alcohol to regurgitate, and there is proof of this condition.
Repercussions of DWI Conviction in Missouri
A DWI is a criminal offense in Missouri. If the DWI arrest leads to a conviction, the offender will face significant penalties depending on the BAC level and the number of previous alcohol-related convictions. These include:
Installation of vehicle ignition interlock devices
Higher insurance rates
A blood alcohol level of .08 or more is considered legally drunk for non-commercial drivers over 21. Those driving commercial vehicles, including school buses, are legally intoxicated if they have a blood alcohol level of at least .04 percent. A driver under 21 with a blood alcohol level of .02 or higher is considered legally drunk and will suffer particularly harsh penalties under Missouri’s zero-tolerance laws.

Frequently Asked Questions About Missouri DWI Arrests
What Is the Difference Between a DWI Arrest and a DUI?
Under Missouri law, there is no difference between DWI (driving while intoxicated) and DUI (driving under the influence). These interchangeable terms refer to drunk drivers legally impaired by alcohol or drugs, with a BAC above .08 or higher (.04 for commercial drivers).
What Happens if You Refuse a Field Sobriety Test in Missouri?
While field sobriety tests are voluntary in Missouri, those who refuse to take them may be arrested. A driver’s license is not automatically suspended if the driver refuses the field sobriety test.
Can You Refuse a Chemical Test After a DWI Arrest in Missouri?
Missouri law requires you to submit a chemical test after being arrested for DWI. Despite Missouri’s “implied consent” law, you may refuse to take an alcohol or drug test. Nonetheless, if you refuse, you risk losing your Missouri driving privilege for a year, also known as a chemical revocation.
Can a DWI Be Dismissed in Missouri?
In Missouri, a person may be able to get their DWI charges dismissed if they can prove the following:
They were not driving at the time of the incident.
The arresting police officers did not have probable cause to stop you for DWI suspicion.
The arresting officers deviated from the standardized field sobriety test and incorrectly administered the breath or chemical tests.
In other circumstances, they may be able to have their charges reduced to one with more lenient penalties.
If you are facing DWI charges in Missouri, you must speak with an experienced Missouri DWI Lawyer as soon as possible.
