Cringe! I did so each time I heard the pre-recorded warning messages on the AirTrain at the San Francisco International Airport. Even worse was that the previous sentence also ended with “on.” Even the web site above phrases it better: “For your safety, please set the brake once you board an AirTrain car…”. Ah, “set” is much better than “turn to on.” I thought “engage” would work, but perhaps that’s too technical. Thousands of people hear this recording every day, the least SFO could do is make the syntax pleasant.
