Missouri Dui/Dwi Process

If you are stopped by an officer for a DUI in Missouri, it helps to know the process. But first, we have to talk about what constitutes DUI/DWI in Missouri.

The Missouri DUI Process

Quite a lot of motorists get stopped for driving under the influence (DUI) or Driving while intoxicated (DWI)  Sometimes, people also say Driving while impaired for DUI.

In the eyes of the law, they refer to the same thing. All DUI/DWI talk about a motorist driving in an intoxicated condition.

The intoxication does not mean only alcohol, but can also be drugs or controlled substances.

Any officer can stop you for inspection as long as they have probable cause. If you are stopped for the investigation and asked to do the BAC test, it is highly recommended to submit to the test, since they can suspend your license immediately.

Once you are asked to pull over by the police officer, the authorities will be looking for any hints of impairment. Some red flags include:

  1. Stammering, mumbling or speaking unclearly,
  2. Inability to focus on the officer,
  3.  Rambling communications, and the like.

The authorities will then subject you to what the law calls as the field sobriety test.  Some tests include:

  1. Trying to balance on one foot, alternating between left and right,
  2. Asking the motorist to have their eyes follow a light while keeping your neck, shoulders and other body parts steady,
  3. Walking in a straight line, and asking the motorist to stop, continue and walk back with proper balance.

Not performing well with these tests can lead you to get a blood alcohol concentration test.

MISSOURI DUI DWI BAC TEST

The BAC test can be a blood test, a breathing analyzer test or even a chemical test.

Motorists usually get the examination at the nearest police station after getting stopped.

Under the law, you are in an intoxicated condition if:

  1.  a commercial driver with a blood alcohol concentration of .04 or
  2. a motorist with a BAC of .08.

Lastly, even if your BAC test is lower than .08, the police can still attach a violation. If the officer can submit sufficient proof, the motorist can still get a DUI for dangerously driving due to intoxication.

MISSOURI DUI PENALTIES

The first DUI offense can lead to:

  1.  Prison time, up to 6 months.
  2. A fine of $500,
  3. Full suspension of license for 30 days and restricting your license for 60 days.

The second DUI can lead to:

  1. 1 year in jail,
  2. Fines up to $1,000,
  3. license suspension of a year,
  4.  5 years suspension if the second offense was within 5 years from the first offense.
