How long do interlock requirements last after a DUI?

On Behalf of | May 30, 2024 | DUI

The Oklahoma criminal courts have the authority to impose a number of different penalties for different criminal charges. Someone convicted of a driving under the influence (DUI) offense due to either an elevated blood alcohol concentration (BAC) or obviously diminished ability while driving could potentially face incarceration and financial penalties.

The penalties can also affect someone’s driving privileges. Unlike many other states that automatically suspend the driver’s license of motorists convicted of drunk driving, Oklahoma is a bit more lenient. Specifically, the state requires that drivers install ignition interlock devices (IIDs) in their vehicles after a DUI conviction instead of outright terminating their driving privileges.

An IID costs money to install and maintain. Many people also find the requirement to perform a test every time they drive to be rather embarrassing. How long does someone need to maintain an IID in their vehicle after a DUI conviction in Oklahoma?

IIDs may be necessary for up to five years

Someone subject to an IID requirement cannot legally drive any vehicle that does not have an IID installed. Both personal vehicles and any vehicles that someone drives for employment must have a device installed. The motorist must perform a test whenever they start the vehicle and during their drive time as well.

The driver also needs to regularly take the vehicle for IID maintenance and calibration. How long the driver must maintain IIDs in each of their vehicles depends on how many DUI infractions they have on their record. A first DUI conviction usually leads to an 18-month IID requirement. Those convicted of a second DUI must maintain a DUI in their vehicle for four years before they regain their full driving privileges. Third and subsequent offenses lead to a five-year IID requirement.

It is often preferable to defend against a DUI charge rather than pleading guilty and leaving oneself effectively at the mercy of the courts. Motorists who understand the penalties that the courts may impose for a DUI conviction can make more informed decisions regarding how they respond to criminal allegations. Successfully defending against a DUI charge can help someone avoid a criminal record and licensing penalties that could cause career setbacks and personal embarrassment.
