Short answer
Short answer. Oklahoma law requires drivers to stay on the right half of the road, to drive only in the posted direction on one-way streets, and to use only the right-hand roadway of a divided highway (47 O.S. §§ 11-301, 11-308, 11-311). Fault is still decided on the evidence and compared (23 O.S. §§ 13–14).

What Oklahoma's direction-of-travel laws say
Several short statutes set the rules a wrong-way driver breaks:
- Drive on the right. "Upon all roadways of sufficient width a vehicle shall be driven upon the right half of the roadway," with listed exceptions such as passing or an obstruction (47 O.S. § 11-301(A)).
- Multi-lane two-way roads. On a road with four or more lanes for two-way traffic, "no vehicle shall be driven to the left of the center line," except where traffic-control devices allow it or to turn left into an alley, private road or driveway (§ 11-301(C)).
- One-way streets. "Upon a roadway designated and signposted for one-way traffic, a vehicle shall be driven only in the direction designated" (47 O.S. § 11-308(B)).
- Divided highways. Where a highway is divided by a space, barrier or dividing section, "every vehicle shall be driven only upon the right-hand roadway," and crossing the divider is allowed only at permanent openings or crossovers (47 O.S. § 11-311).
- Interstates and other controlled-access roads. "No person shall drive a vehicle onto or from any controlled-access roadway except at such entrances and exits as are established by public authority" (47 O.S. § 11-312). That's the rule behind a driver who enters a highway by an exit ramp.
A traffic citation and a civil injury claim are separate. A driver can be cited, or not, and the civil question of fault is decided on its own evidence.

Where wrong-way crashes happen in the OKC metro
Wrong-way crashes fall into a few patterns, each with different evidence:
- Interstates and highways, such as I-35, I-40, I-44 and I-240, often after a driver enters by an exit ramp. On a highway, the Oklahoma Highway Patrol or a city police department may investigate. See the corridor guides for I-35 and I-40.
- Downtown one-way streets, where a driver turns the wrong way.
- Divided boulevards, where a driver turns into the far-side lanes.
- Two-lane roads, where a driver crosses the center line on a curve or while passing.
Who is at fault in a wrong-way crash?
The wrong-way driver's conduct usually takes center stage, but Oklahoma still compares fault:
- Your own negligence doesn't bar recovery unless it is of greater degree than the negligence of the person, or the combined negligence of the people, who caused the harm (23 O.S. § 13).
- If you can recover, your damages are reduced in proportion to your share (23 O.S. § 14).
An insurer may ask whether you were speeding, distracted, or had time to avoid the car. Other parties can also matter. For example, an employer may be involved if the wrong-way driver was working. Those are fact questions for a lawyer. If the wrong-way driver may have been impaired, see hit by a drunk driver. For how fault is argued generally, see who is at fault after an Oklahoma car accident.

Evidence that matters after a wrong-way crash
- Where the other car entered. The ramp, turn or median crossing the wrong-way driver used. Witness accounts and 911 calls may describe the car before the crash.
- Video. Traffic cameras, business cameras and dashcams. Private video can be overwritten quickly, so ask early.
- The crash report. The diagram, narrative and any citation. See how to get your Oklahoma crash report.
- Vehicle event data. Speed and braking before impact. See vehicle event data after a crash.
- Signs and markings at the ramp or turn, photographed only when it's safe.
What to do after a wrong-way crash in OKC
- Give your information and reasonable help to anyone injured. In a crash that injures or kills someone or damages a vehicle someone is driving or attending, each driver must give their name, address and vehicle registration number, show their driver license and security verification form on request, and give reasonable assistance to anyone injured (47 O.S. § 10-104). If anyone is hurt, notify police "by the quickest means of communication" (47 O.S. § 10-107).
- Note the agency that responds: Oklahoma City Police, the Highway Patrol, or another city's police.
- Get medical care, and keep every record. See who pays medical bills after a wreck.
- Write down what you saw, including where the other car came from, as soon as you can.
- Be careful with insurer calls. See insurance calls after a wreck.

Whose insurance pays
The wrong-way driver's liability coverage is usually the first source. Oklahoma requires liability coverage (47 O.S. § 7-601). If that driver had no insurance or not enough, your uninsured/underinsured motorist (UM/UIM) coverage may apply unless it was rejected in writing (36 O.S. § 3636). See uninsured motorist claims. For how losses are measured and what can reduce them, see what shapes car accident compensation.

Wrong-side and wrong-way driving in Oklahoma City fatal crashes: federal data
Federal data covers fatal crashes only. In NHTSA's Fatality Analysis Reporting System (FARS), a driver in Oklahoma City was coded as driving on the wrong side of a two-way road, or the wrong way on a one-way road, in 2 fatal crashes in 2022, 4 in 2023 and 3 in 2024 (preliminary FARS file). The wrong-side code covers any driver on the wrong side of a two-way road, including one who crossed the center line, so not every crash counted here is a wrong-way crash in the everyday sense. Only one (2024) was coded as driving the wrong way on a one-way trafficway. These counts depend on how factors were recorded, and they don't include non-fatal crashes.

Deadlines
For most Oklahoma injury claims, the lawsuit deadline is two years (12 O.S. § 95(A)(3)). A crash with a government vehicle has written-notice rules that come sooner. See Oklahoma car accident deadlines.

Common questions
Is the wrong-way driver always at fault in Oklahoma?
Not automatically. Oklahoma's direction-of-travel statutes set clear duties (47 O.S. §§ 11-301, 11-308, 11-311), but fault is decided on the evidence and compared under 23 O.S. §§ 13–14.
What law covers driving the wrong way on a highway ramp?
47 O.S. § 11-312 says no one may drive onto or from a controlled-access roadway except at the entrances and exits established by public authority.
Who investigates a wrong-way crash on an OKC interstate?
It may be the Oklahoma Highway Patrol or a city police department, depending on where the crash happened. Check the agency on your paperwork before requesting the report.
What if the wrong-way driver had no insurance?
Your uninsured-motorist coverage may apply unless it was rejected in writing (36 O.S. § 3636).
How long do I have to file a claim?
For most Oklahoma injury claims, two years (12 O.S. § 95(A)(3)). Government-vehicle claims have earlier notice rules.
