When you are arrested for a driving while intoxicated offense, a police officer will ask you to submit to a chemical test to determine your blood alcohol content or drug level. While the state of Missouri deems you to have consented to such testing under its "implied consent" law, you may refuse to submit to the test.

However, if you refuse to take the alcohol or drug test, your Missouri driving privilege will be revoked for one year. This is known as a "Chemical Revocation".

Information 24/7 – If you have questions about a ticket, suspension, or revocation on your Missouri driver record, you may now call our new interactive voice response system at (573) 526-2407 - available 24 hours a day, 7 days a week.

After you serve the first 90 days of your Chemical Revocation, you may be eligible for a Limited Driving Privilege (LDP). The LDP may be used for work, your alcohol program, medical treatment, school, etc.

If your driver driver record shows more than one alcohol- or drug-related law enforcement contact, you are required to have an IID installed on any vehicle you operate. You must maintain the device for 6 months (from your date of reinstatement) without violation. A violation will result in an additional 6-month extension of the IID requirement. For more information about the IID requirement, visit the Ignition Interlock Device (IID) page of our website.

An SR-22 form is an insurance filing from your insurance company that shows your motor vehicle has liability insurance.

You must file the SR-22 form for two years from the effective date of your Chemical Revocation.

If you have an alcohol offense, such as an alcohol or drug revocation on your driver record, the law requires you to complete a SATOP (or comparable course) as a condition of reinstating your driving privilege in Missouri.

To request a hearing, you must petition the Circuit or Associate Circuit Court in the county where the arrest or stop occurred. A petition for review must be filed within 30 days from the date the Notice of Revocation is issued.

If the arrest or stop occurred in another state, you must petition the Cole County Circuit Court, in Jefferson City, Missouri.

A Chemical Revocation (for refusal to submit to an alcohol or drug test) is a permanent part of the record and can never be removed.
