Explanation:
The two legal foundations for making a vehicle stop are probable cause and reasonable suspicion. Probable cause is the standard used when judges issue warrants or when police operate in exigent circumstances. Reasonable suspicion is a lower standard and allows police to stop and frisk people on the street if they have a reasonable suspicion that the person has committed, is in the process of committing, or is about to commit a crime.
