Can I make a citizen's arrest if I see a driver on their cell phone?

aa-cellQ: "Can I issue a citizen's citation, or conduct a misdemeanor citizen's arrest when I see someone driving while using a cell phone? -- Derek in Olympia A: "Derek, thanks for the question. I know it's frustrating when you're driving down the road watching them on their cellphone, not paying attention, but you cannot make a citizens arrest. It is actually an infraction and not a misdemeanor to be talking on the phone while driving." -- King County Sgt. Cindi West
