Reasonable suspicion is a less demanding standard than probable cause not only that reasonable suspicion can be established with information that is different in quantity or content than that required to establish probable cause, but reasonable suspicion can arise from less reliable information than probable cause.
Reasonable suspicion is the standard for a traffic stop or detention. Reasonable suspicion is a lower standard than probable cause for arrest. Reasonable suspicion for a traffic stop requires more than a hunch.
Probable cause requires more than reasonable suspicion. Probable cause (PC) is basically more likely than not. PC is required for arrest or a search warrant.
