Definition - What does Traffic Stop mean?
A traffic stop is when a law enforcement officer pulls over a vehicle to the side of the road due to suspected or observed violations of the law.

Justipedia explains Traffic Stop
There are a number of reasons why a person could be pulled over for a traffic stop by a police officer. For example, the driver could be caught speeding; he or she could be displaying driving behavior indicative of being under the influence, such as swerving; he or she could run a red light, etc. During a traffic stop, a police officer will typically ask for the driver's license and registration, and check them against computer records to see if there are any outstanding warrants against the driver. If there are, he or she will be arrested.
