Failure to Maintain Lane: A Cop’s Most Used Weapon in DUI’s

In the State of Georgia, police officers can use the offense of “failure to maintain lane” as a tool to initiate a traffic stop and potentially investigate a driver for suspicion of driving under the influence (DUI). This offense occurs when a driver fails to stay within their lane while driving on the road.

When a police officer observes a vehicle crossing lane lines, or exhibiting other signs of erratic driving that may indicate impairment, they can use this as reasonable suspicion to pull the driver over. O.C.G.A. § 40-6-48 states that “a vehicle shall be driven as nearly as practicable entirely within a single lane.” It prohibits drivers from leaving their lane until they have determined that a lane change can be made safely. NOTE: weaving within your lane is NOT a failure to maintain lane- the vehicle must cross or touch lane lines. Once the vehicle is stopped, the officer may then proceed with further investigation, which could include administering field sobriety tests or breathalyzer tests to determine if the driver is under the influence of alcohol or drugs.

It’s important to note that while failure to maintain lane can be a legitimate reason for a traffic stop, officers must still follow proper procedures and have reasonable suspicion of DUI to detain and arrest a driver. This means they must observe additional signs of impairment beyond just the lane deviation. It is usually accompanied by “bloodshot eyes”, or “odor of alcohol.” If you get pulled over for a DUI, call us immediately.
