A driver does not have to cross a lane line for driving behavior to raise a legal question. In State v. Johnson, decided August 18, 2017, the North Carolina Supreme Court considered a truck that accelerated, turned, and fishtailed on a snowy evening.
The court held that the officer had reasonable suspicion to stop the truck for unsafe driving under the circumstances. It reversed the Court of Appeals and upheld the superior court’s denial of suppression.
The supported observations
Snow was falling and slush had begun accumulating. The officer was next to the truck at a red light. When the light changed, the truck accelerated abruptly and turned left, fishtailing before the driver regained control. The driver remained in the lane.
The court evaluated those circumstances together rather than treating a legally permitted left turn as the only relevant fact. Reasonable suspicion concerns an objective basis to investigate; it does not require proof of the ultimate DWI charge before the vehicle is stopped.
“abruptly accelerated”State v. Johnson (N.C. 2017), describing a supported observation in the suppression record.
What a weather-related stop review should include
A general weather report for a nearby city may not establish the surface condition at a particular intersection. Conversely, the absence of a weather photograph does not erase testimony. Counsel should assess the available evidence and its limits, including camera angle, lighting, and the timing of any later photographs.
| Context | Useful question |
|---|---|
| Road and weather | What conditions existed at that location and time? |
| Vehicle movement | What did the officer observe, and for how long? |
| Record support | Do video, testimony, and other records agree? |
The limit of the decision
Johnson does not mean every tire slip justifies a stop, nor does it mean a valid stop proves impairment. The particular observations supported the court’s ruling. A defense review still examines the subsequent investigation, arrest, testing, and proof of the charged offense. The practical lesson is to preserve environmental context alongside the driver’s account.
Questions people ask
Does staying in the lane make a stop unlawful?
Not automatically. Other supported observations and road conditions may matter.
Does the reason for the stop need its own review?
Yes. It should be evaluated separately from evidence gathered after the stop.
