Missouri’s ignition interlock laws

On Behalf of | Jul 21, 2020 | Duis And Traffic Violations |

Around the country, most states have adopted some required use of ignition interlock devices for select persons charged with drunk driving offenses. The laws vary by state and may also vary based upon the presence of any previous offenses on a driver’s record.

An ignition interlock device keeps a vehicle’s ignition locked and unable to be started until the driver successfully passes a breath test proving they are not impaired by alcohol at the time. They must also take additional tests while driving to prove they have not consumed alcohol after starting their vehicle.

Missouri’s use of ignition interlock devices

According to the Missouri Department of Transportation, a person convicted of a drunk driving after previously having been convicted of such an offense may be mandated to install and use an ignition interlock device. The use of an IID may be linked to the driver’s ability to reinstate their driving privileges during a period of suspension or revocation of those privileges.

The Missouri Department of Revenue explains that even if a person has not been convicted of an impaired driving offense, they may still experience administrative penalties related to the arrest. These penalties may include the revocation or suspension of their driving privileges.

Accidents and IIDs

In addition to incurring costs associated with the use of an ignition interlock device, drivers must navigate the dangers of using these handheld devices while driving. A report by Car and Driver magazine highlights how these devices contribute to distracted driving. In fact, many vehicle crashes have been associated with a driver’s required participation in a rolling retest.
