There's a sign on the interstate between my apartment and where I work; one of those temporary flashing signs on the side of the road. The message it flashes reads, "PUT ON THE BRAKES" in the first frame and "TOWARD ZERO DEATHS" in the second. That's all it says.
I'm not sure who decides what goes up on these things, or even how they decide where they will go...but I think whoever they are needs to think about the message they are promoting. "put on the breaks" generally means "stop," (right?) and "toward zero deaths" generally means "in the direction in which no more people die...or more people are alive." Therefore, the message on the interstate is "stop letting people live" or maybe "make more people die" I'm not sure what they were going for, but I think they've failed at promoting safe driving.
