When Does a DUI Become a Felony in Oklahoma?

One of the most common felony DUI situations involves a new DUI after a qualifying prior DUI conviction or deferred sentence. If the new violation occurs within the applicable ten-year period, the new DUI is a Class C2 felony.

A felony can also arise when two or more separate DUI violations are committed within one year. Oklahoma now allows those allegations to be combined and prosecuted as a single Class C2 felony, which means a person does not necessarily need to be convicted of the first DUI before a later allegation creates felony exposure.

The classification becomes more serious when the person's prior DUI was already a felony. A new DUI after one prior felony DUI is a Class B4 felony, while a new DUI after two prior felony DUI convictions is a Class B3 felony.

A Felony DUI Case Has Two Different Parts

In a repeat DUI case, prosecutors have more to establish than the existence of an old criminal case. They still need evidence supporting the new DUI allegation, and they also need a prior case that legally qualifies to make the new charge a felony.

Those two issues can lead to very different kinds of review. The current DUI may involve the traffic stop, video, field sobriety tests, officer observations, breath or blood testing, and statements, while the felony classification may depend on old judgments, deferred sentences, probation dates, prior felony classifications, and records from another court or another state.

A strong current DUI case does not automatically establish the felony enhancement. At the same time, finding an issue with the prior record does not make strong evidence of the current DUI disappear, so both parts of the case have to be examined separately.

The Ten-Year Rule Does Not Start With the Arrest Date

People sometimes look at the date of an old DUI arrest and assume that ten years later the case can no longer be used. Oklahoma does not calculate the felony DUI period that way.

For the repeat DUI provision, the ten-year period runs from the completion of the earlier sentence or deferred judgment. A deferred sentence is also treated as a conviction for DUI enhancement purposes for ten years after completion of the court ordered probation.

This can produce a much longer period between the original DUI arrest and the date on which the prior case stops affecting a later DUI. The judgment, sentence, probation dates, and final disposition from the prior case need to be read before deciding whether the new case is actually a felony.

A Prior Deferred DUI Can Make a Later DUI a Felony

A deferred sentence is not ignored simply because the earlier case did not end with an ordinary conviction. Oklahoma specifically allows a qualifying prior deferred DUI to be used when determining whether a later DUI is a felony.

The dates remain important. A deferred judgment is treated as a conviction for this purpose for ten years after the person completes the court imposed probationary term, so the end of probation is more important than the date the person entered the plea.

Not Every Prior DUI From Another State Counts

A DUI conviction from another state can be used to increase Oklahoma DUI punishment when it qualifies under Oklahoma law. There is an important exception for an out of state conviction based on a blood or breath alcohol concentration below .08, because Oklahoma does not allow that conviction to be used to enhance punishment under its felony DUI provisions.

The paperwork from the other state needs to show what the person was actually convicted of. The name of the offense alone may not answer the question because another state's impaired driving laws and alcohol limits may not match Oklahoma's.

Two DUI Allegations Within One Year

Oklahoma now permits prosecutors to combine two or more separate DUI violations committed by the same person within one year and prosecute them as one Class C2 felony. This is different from the traditional repeat DUI rule because the State does not need to wait for a conviction in the first case before using the aggregation provision.

This becomes particularly important when someone is arrested for a second DUI while the first case is still pending. A person should not assume that two unresolved DUI cases will simply remain two separate misdemeanor charges.

If the alleged violations happened in different counties, the aggregated felony charge is filed in the county where the last alleged violation occurred. Once that aggregated charge is filed, a pending underlying charge in another county is dismissed without prejudice.

Prior Felony DUI Convictions Increase the Classification

The ten year rule discussed above is not the only way prior history affects a DUI. Once the prior DUI itself was a felony, a later DUI falls into a higher felony classification.

A new DUI after one prior felony DUI is a Class B4 felony. The punishment includes one (1) to ten (10) years in prison, a fine of up to $5,000, 240 hours of community service, alcohol and drug assessment and treatment requirements, and an ignition interlock requirement.

A new DUI after two prior felony DUI convictions is a Class B3 felony. The prison range increases to one (1) to twenty (20) years, and the sentence also includes a fine of up to $5,000, 480 hours of community service, at least one year of supervision and periodic testing, treatment requirements, and an ignition interlock device for at least ninety days.

Oklahoma also has a much more serious provision for a person who has a prior conviction for second degree murder or first degree manslaughter in which the death resulted from DUI and is later convicted of another DUI. That offense is a Class A2 felony with a prison range of five (5) to twenty (20) years and a fine of up to $10,000. Further, both of those offenses are 85 percent crimes.

Punishment for a Class C2 Felony DUI

The most common first felony DUI classification is Class C2. Under Oklahoma's current felony classification system, Class C2 no longer has one fixed prison range that applies to everyone.

If the person does not have separate prior Class C or Class D felony convictions that increase the class punishment, the prison sentence is up to seven (7) years. One or two prior Class C or Class D felonies increase the range to two (2) to ten (10) years, while three such felonies, or certain more serious prior felony classifications, increase the range to two (2) to twelve (12) years.

A Class C2 repeat DUI also carries a fine of up to $2,500, assessment and treatment requirements, and an ignition interlock requirement. If the treatment does not include at least five days of residential or inpatient treatment, the person must serve at least five days in custody.

The one year aggregation offense is also a Class C2 felony and uses the Class C2 punishment system. It carries a fine of up to $2,500 and requires assessment and compliance with the treatment recommendations.

A Felony DUI Conviction Has Additional Requirements

Felony DUI punishment is not limited to a prison sentence or fine. Oklahoma requires a person found guilty of a felony DUI to submit to electronic monitoring, and DUI convictions also carry alcohol and drug assessment and treatment requirements. A Victim’s Impact Panel is also required when the program is offered in the county where judgment is entered.

Aggravated DUI Is a Different Type of Felony DUI

Aggravated DUI is a separate felony category and does not require an earlier DUI conviction. It is based on circumstances surrounding the new DUI itself rather than relying on a prior DUI record to create the felony.

A person facing a first time DUI can still be charged with aggravated DUI when the statutory aggravating circumstances are alleged. Prior DUI history can then change the punishment further, which is why an aggravated DUI and a repeat felony DUI should not be treated as the same charge.

The Evidence in the New DUI Still Matters

A prior DUI record does not substitute for evidence of the new offense. The traffic stop, arrest, field sobriety tests, officer observations, video, statements, and chemical testing still determine how strong the underlying DUI allegation is.

A properly admitted .08 or higher alcohol test supported by video and officer observations can make the current DUI difficult to dismiss. Review of the evidence is still necessary, but the existence of a felony charge coupled with the evidence does not mean that review of the stop or testing will produce a dismissal.

The prior record side of the case deserves the same level of attention. An old case that does not qualify, falls outside the applicable time period, or was based on an out of state offense that Oklahoma cannot use for enhancement may change the classification even when the evidence in the new DUI case is strong.

The Traffic Stop and Arrest Still Have to Be Lawful

Police need a lawful reason to stop the vehicle, and the arrest must be supported by probable cause. Available body camera and dash camera video can be compared with the officer's written account of the driving, the stop, field sobriety tests, statements, and arrest.

If the stop was unlawful, evidence obtained afterward may become the subject of a motion to suppress. A felony DUI should not be treated as though the prior record eliminates constitutional issues involving the new arrest.

The Driver's License Case Is Separate

The felony criminal case and the driver's license process are separate. A qualifying .08 or higher test result or refusal leads to action through Service Oklahoma even while the felony case is pending in district court.

Keep the driver's license paperwork with the criminal case documents, but do not assume the felony court case will resolve the license issue. The test or refusal, revocation notice, prior driving history, and IDAP status need to be addressed through the separate driver's license process.

What Should You Do After a Felony DUI Arrest?

Keep the paperwork from the arrest, jail, court, Service Oklahoma, and any prior DUI cases you still have. Old judgments, deferred-sentence paperwork, probation records, and information showing when the earlier sentence or probation ended can be especially useful in determining whether the new DUI is properly classified as a felony.

Write down what happened during the new arrest while the details are fresh. Do not contact the officer to explain what happened or try to correct a prior statement, and if police want to question you further about the alleged offense, you should decline to answer questions and ask to speak with a lawyer.

Frequently Asked Questions About Felony DUI

Is a second DUI automatically a felony in Oklahoma?

No. Whether a later DUI is a felony depends on the prior case, its disposition, when the earlier sentence or deferred judgment ended, and whether the new allegation falls within the statutory period.

Oklahoma's separate one year aggregation law can also create a Class C2 felony even when the first DUI has not yet resulted in a conviction. The actual chronology of both cases needs to be checked.

Does a deferred sentence for DUI count as a prior DUI?

Yes. Oklahoma treats a qualifying deferred DUI as a conviction for DUI enhancement purposes for ten years after completion of the court imposed probationary term. A person should not assume that an old DUI is irrelevant merely because it ended in a deferred sentence. The probation completion date is particularly important.

How far back can Oklahoma use a prior DUI?

For the traditional repeat DUI provision, the ten-year period is tied to completion of the earlier sentence or deferred judgment rather than the original arrest date. That can make the usable period considerably longer than someone expects when looking only at the date of the old arrest. Prior felony DUI convictions are treated differently because the higher felony provisions do not use that same ten-year language. The classification needs to be determined from the exact prior record.

What if the first DUI is still pending when I get another DUI?

Oklahoma now allows two or more separate DUI violations within one year to be aggregated and prosecuted as a single Class C2 felony. A conviction in the first case is not required before prosecutors use that provision.

This means a second DUI allegation while the first case is still pending can create felony exposure even though the person has never previously been convicted of DUI. The dates of the alleged violations control whether the one year provision is available.

Is felony DUI the same thing as aggravated DUI?

No. A repeat felony DUI is usually a felony because of the person's prior DUI history, while aggravated DUI becomes a felony because of circumstances surrounding the new incident.

Someone can face aggravated DUI without any prior DUI conviction. A prior record can then affect the punishment if aggravated DUI is charged.

What is the punishment for a felony DUI in Oklahoma?

There is no single punishment range for every felony DUI. A Class C2 felony DUI starts with a prison range of up to seven (7) years when no other felony history increases the class punishment, while prior felony DUI convictions move later DUI charges into Class B4 or Class B3 with substantially higher ranges.

The complete punishment also includes fines and, depending on the felony level, treatment, community service, supervision, testing, ignition interlock requirements, electronic monitoring, and other statutory requirements. The prior record has to be reviewed before an accurate punishment range can be given.

Can a felony DUI be dismissed?

Yes, but DUI cases are not easy to get dismissed simply because a lawyer reviews the stop, testing, or video. A legitimate constitutional, evidentiary, or prior record problem has to exist before one of those issues materially changes the prosecution.

A felony DUI does create an additional area that does not exist in an ordinary first DUI: the State's use of the prior record. Even when the current DUI evidence is strong, a prior case that does not legally qualify can affect whether the new charge is properly filed as a felony.
