回複：我準備下周出庭，罰單上說是walk in。這樣的case警察不用出庭麽？

很抱歉老貓沒有參與過您所在州的交通庭的審判流程,但是老貓懷疑您所說的可能是 walk in traffice school.

相關法庭審理的問題,請您參考這個資料

For most infractions you can send a letter to your court asking for a court trial or a trial by mail (also called a "trial by written declaration"). You'll have to pay the bail even if you want to have a trial. Send your letter by certified or registered mail, at least 5 days before the "appearance date" on your ticket.
