Nevada Engine & Jake Brake Rules

Nevada ties it to the muffler (NRS 484D.285): use a compression brake only if it runs through an operational muffler, or in a real emergency. Break that and it is a misdemeanor. General muffler rules sit in NRS 484D.415. The actual 'no engine brake' signs are local, common around Lake Tahoe towns like Incline Village and residential edges near Reno and Carson City. Keep the brake on grades where nothing is posted.
