Most drivers are aware that under certain circumstances, a police officer is authorized to pull over vehicles and conduct a traffic stop. What does the law say, though, about what kind of situation allows the officer to legally initiate a traffic stop? Is a traffic stop only allowed if there is a major traffic violation, or do minor ones allow the stop as well?
New York Case Law
According to New York case law, an officer can initiate a traffic stop when that officer has “probable cause to believe that a driver has committed a traffic violation.” The officer uses the entirety of the circumstances to determine whether the driver has committed a traffic violation. The officer can observe any range of traffic violations, whether major or minor. The legal standard is that the officer must have probable cause, i.e. a reasonable basis, for believing that the driver at issue did in fact commit a traffic violation.
Crossing the Fog Line
In a recent case decided by New York’s highest court, the Court of Appeals, the defendant argued that when an officer pulled him over for swerving, the officer did not have probable cause to believe he committed a traffic violation (and therefore that the officer violated the defendant’s rights). In this case, police officers testified that they saw the defendant cross the fog line in the road three times within a tenth of a mile before they pulled him over under suspicion of driving while intoxicated.
