Missouri DWI Laws & Penalties

Missouri DWI

The state of Missouri persues both Missouri DWI and Missouri DUIcases. A Missouri DWI commonly refers to a drunk driving violation, whereas a DUI refers to driving while under the influence of drugs. If you are arrested for a Missouri DWI it means that you were driving with a blood alcohol level of .08% or greater. This is true only of tests administered up to three hours after the arrest. The Missouri "per se" law allows police to arrest (and the courts to convict) even if your ability to drive was not impaired if you submitted a chemical test of .08% or greater.

If you are arrested on charges of Missouri DWI and refuse to take the blood alcohol test, or if you did take the test and you were above the legal limit, you can lose your license. You have fifteen days after the arrest to take action to protect your driving privilege. It is crucial to have the help of a lawyer for this! 

Penalties for Missouri DWI

A Missouri DWI is considered a misdemeanor, provided it is a first offense. In this case, you will be facing a possible jail sentence of up to six months. Also, you will have to pay a fine that cannot exceed $500. Keep in mind, though, that you will also be responsible for paying for your court and incarceration costs. You will lose your license for 30 days, and also face a 60-day restricted driving period. During this restricted time you can drive to and from work and your alcohol education classes. Also, this will be part of your permanent driving record. 

A Missouri DWI conviction also carries the requirement of attending the Substance Abuse Traffic Offender Program, or SATOP. The SATOP class costs $190. You will also have to pay to have your license reinstated when you complete the class. 

The court also has the option to ask a first time Missouri DWI arrestee to drive only with an ignition interlock device for the duration of the probation period, which is 1 to 2 years. This device will keep the car from starting when the driver has alcohol in his system. This device comes with a monthly maintenance fee that will be your responsibility. 

Finally, remember that your Missouri DWI will cause your insurance premiums to increase significantly. No matter if there were injuries or not due to your driving drunk, you will see a huge rise in premiums. You may even lose your current coverage and be forced to seek alternative car insurance.
