You can be charged with DUI in the event that you have a blood alcohol level of 0.08% or higher. Refusal to take a drunk driving test can be used in court and could lead to additional penalties.
First DUI in Missouri is a class B misdemeanor and will result in a 6-month imprisonment, a maximum fine of $500, probation, and suspension of driving privileges. The person will also be required to drive a vehicle fitted with an ignition interlock device. A second offense will warrant a maximum of one year in jail and a maximum fine of $1,000, and possible revocation of driving privileges. An ignition interlock device is also required for persons under probation.
A third offense is a Class D felony. This will require up to four years in prison and up to $5,000 in fines, along with probation and revocation of the person's driver's license for a span of ten years.
A fourth offense is a Class C felony, with the driver now classified as an aggravated offender.
Finally, a fifth offense will lead to 5 to 15 years in prison, up to $5,000 in fines, probation, and revocation of driving privileges. The suspension goes on the driver's permanent record. No hardship license is available for a third, fourth, or a fifth offense.
Motorists who are behind the wheel are deemed to have given consent to have their blood, breath, and urine tested, although the type of test depends on the police officer. Every driver is given 20 minutes to contact a lawyer prior to taking any test, provided that he or she asks to do so.
