A charge or legal shorthand for operating a vehicle while impaired by alcohol, drugs, or another intoxicating substance, OWI is used in some states in place of DUI or DWI.

The exact label changes by state, but the basic idea is the same: a person can be arrested for driving, or in some places simply operating, a vehicle when impairment affects judgment, reaction time, or control. That can involve alcohol, prescription medication, illegal drugs, or a mix of substances. For example, someone weaving across lanes after drinking, or struggling to handle sharp curves and fog on a road like the Blue Ridge Parkway after taking sedating medication, may face this kind of charge even without a crash.

For an injury claim, an OWI-type allegation can strongly affect liability. Evidence of impairment may support a claim that the impaired driver acted negligently, and it can influence settlement value, insurance negotiations, and whether punitive damages are available. Police reports, chemical test results, video, and witness statements often become central evidence.

In North Carolina, the usual charge is DWI, not OWI. Under N.C. Gen. Stat. § 20-138.1 (2024), driving while impaired generally covers a blood alcohol concentration of 0.08 or more, or driving under the influence of an impairing substance. A related criminal case can also shape the timeline and strategy of a connected civil injury case.
