The key differences between reasonable articulable suspicion (RAS) and probable cause (PC) in Maine are:
Reasonable Articulable Suspicion (RAS) If you are cruising down the road in Southern Maine and you commit a traffic violation like running a red light, a Southern Maine police officer has the legal right to briefly stop and detain you. The officer can also pull you over if you are driving recklessly, for example weaving between lanes, or going 20 miles over the posted speed limit. The officer must articulate specific facts that led to their suspicion. Common factors that can establish RAS include the police officer observing traffic violations, erratic driving, or other suspicious behavior.
