What evidence can lead to a DWI charge in Missouri besides blood alcohol concentration?

The presence of erratic driving behavior and an admission of alcohol consumption can serve as substantial evidence for a DWI charge in Missouri, even if the blood alcohol concentration (BAC) does not meet the legal threshold. Law enforcement officers are trained to observe driving patterns that may suggest impairment, such as swerving, accelerating or decelerating unpredictably, or making unsafe lane changes. These behaviors can indicate that a driver is not in full control of their vehicle.

Additionally, if a driver admits to consuming alcohol, this statement can corroborate the observed erratic driving, further solidifying the case for a DWI charge. Officers often look at the totality of circumstances, including movements of the vehicle, behavior of the driver, and any admissions made regarding alcohol consumption, to assess impairment. This combination of factors can persuade a court of the driver’s impaired state, even when BAC tests might not be conclusive.
