Can Police Make a DUI Stop for Weaving Within a Lane in Georgia?

Drivers rarely hold a perfectly straight position in a traffic lane for every second of a trip. A car may drift slightly on a curve, move away from a rough patch of pavement, or require a small steering correction. When a police officer sees the movement and begins following the vehicle, however, the same few seconds of driving can become the basis for a DUI stop.
Georgia law allows officers to investigate suspected impaired driving when their observations create reasonable suspicion. Weaving entirely within a lane can sometimes meet that standard, even when the driver never commits a separate lane violation. Because everything discovered after the blue lights come on may depend on the legality of that initial stop, early guidance from an experienced Atlanta DUI arrest lawyer can help determine exactly what the officer saw before deciding to pull the vehicle over.
A DUI Stop Does Not Require a Completed Traffic Violation
An officer making an investigative traffic stop needs specific, articulable facts that support a reasonable suspicion of criminal activity. Georgia courts apply that standard to suspected DUI stops by examining what the officer observed and the reasonable inferences that could be drawn from the driving.
That threshold is lower than the proof required to convict someone of DUI or even to make an arrest. In Smith v. State, the Georgia Court of Appeals upheld a stop after an officer watched a vehicle weaving erratically back and forth within its lane and could identify no apparent reason for the movement. The officer did not have to wait for the vehicle to cross a lane marker before investigating suspected impairment.
The same principle appears in Semich v. State. Georgia’s Court of Appeals explained that observed weaving can provide sufficient reason for an investigative DUI stop, even when the movement itself is not a traffic offense. In that case, the court considered two instances of weaving together with an abrupt change in direction and the late hour.
Weaving Within a Lane Is Different From Failing to Maintain a Lane
Georgia’s lane statute, O.C.G.A. § 40-6-48, requires a vehicle to be driven “as nearly as practicable” entirely within a single lane and addresses movement from that lane. Weaving back and forth while remaining inside the lane generally does not establish a violation of this statute.
The Georgia Court of Appeals clarified another boundary in Chapman v. State in 2023. Driving on a fog line, without crossing over it, does not violate O.C.G.A. § 40-6-48. The court also recognized the existing distinction between weaving within a lane and committing the separate offense of failing to maintain a lane.
A driver therefore may be stopped for suspected DUI based on a pattern of intra-lane weaving without ultimately being guilty of failure to maintain a lane. The reason for the stop and the traffic charge are separate questions. A court examining the stop looks at whether the officer had a reasonable basis to investigate suspected impairment when the stop began.
The Pattern of Driving Carries More Weight Than a Label
Police reports often reduce several moments of driving to a short phrase such as “weaving within the lane.” That description leaves out much of what determines whether the observation reasonably suggested impairment.
Repeated movement from one side of the lane to the other presents a different factual picture from a brief steering correction. Speed can add another layer. In Veal v. State, the Court of Appeals upheld a DUI stop where the driver was weaving within his lane while traveling approximately 30 miles per hour below the posted speed limit.
Ivey v. State involved still more driving behavior. Before making the stop, the officer saw the driver abruptly brake without an apparent reason, turn back into a shopping center he had just exited, brake abruptly again, and drift across the lane far enough that part of the truck crossed into the fog line. The Court of Appeals considered the complete sequence rather than treating the weaving as an isolated event.
How long the officer followed the vehicle also provides context. A report stating that a car “weaved several times” leaves unanswered whether those movements occurred during a few seconds on a curve or repeatedly over a substantial stretch of road.
Ordinary Steering Corrections Still Have Context
Minor lane movement happens during everyday driving. Curves, changing pavement, construction, potholes, wind, surrounding traffic, and objects near the roadway can all affect where a vehicle sits within its lane. An officer who sees movement must still be able to identify objective facts supporting the decision to investigate.
Georgia cases illustrate why the reason for the movement can matter. In State v. Shaw, the Court of Appeals upheld suppression where it was unclear whether the driver had actually crossed the right white line and the evidence indicated that any movement toward or across the line occurred while avoiding a patrol car that was itself drifting into the driver’s lane.
An ordinary correction therefore deserves to be viewed in the setting in which it occurred. Road design, traffic, nearby vehicles, the location of lane markings, and the distance traveled can provide information that disappears when the encounter is summarized later as simply “weaving.”
Georgia law does not create a numerical rule under which one movement is acceptable and a particular number automatically creates reasonable suspicion. Courts examine the facts surrounding the driving and the observations the officer had before activating the emergency lights.
Patrol Video Can Show What “Weaving” Actually Looked Like
Dash-camera footage can be especially valuable when the legality of the stop depends on a short period of driving. It may show how far the vehicle moved, how often the movement occurred, whether a tire touched or crossed a line, and what was happening on the roadway at the same time.
Video can also expose differences between the report and the actual driving. A written description may make several small corrections sound like continuous swerving. Footage may instead confirm pronounced side-to-side movement over a significant distance. Either possibility is easier to evaluate from the recording than from a few words written after the arrest.
Recent Georgia decisions also distinguish touching a lane boundary from crossing it. Chapman held that merely driving on the fog line is not a violation of O.C.G.A. § 40-6-48, while Georgia precedent has long recognized that repeated erratic movement may independently contribute to reasonable suspicion of DUI.
What Happened After the Stop Cannot Replace the Reason for Starting It
Once an officer approaches a vehicle, additional evidence may emerge quickly. The officer may report an odor of alcohol, ask questions about drinking, request field sobriety testing, or eventually seek a breath or blood test. Georgia DUI charges themselves are governed by O.C.G.A. § 40-6-391.
Those later observations cannot supply facts the officer lacked when the vehicle was initially stopped. The legality of the stop begins with what was known beforehand. In State v. Goodman, the Georgia Court of Appeals emphasized that an investigative stop requires specific, articulable facts rather than an officer’s generalized suspicion or hunch. The court upheld suppression where the driving observed before the stop did not reasonably support the officer’s suspicion of DUI.
For a DUI case that began with alleged weaving, reconstructing those first moments can be critical. A careful review with an experienced Atlanta DUI arrest lawyer can compare the officer’s stated reason for the stop with the patrol video, roadway conditions, lane markings, and the sequence described in the police report.

A DUI case can develop from only a few seconds of driving observed through a patrol-car windshield. When the stop was based on weaving within a lane, the details behind that description may determine whether the officer saw a meaningful pattern of erratic driving or ordinary movement that lacked a sufficient basis for detention.
If you were arrested for DUI after an officer claimed that your vehicle was weaving, contact The Spizman Firm today to speak with an experienced Atlanta DUI arrest lawyer about the circumstances that led to the stop and the evidence recorded before the officer activated the blue lights.
