I saw a sign the other day in Midland Ont. that read “radar speed controlled”. I’m almost certain that this is what the sign had written on it; I’ve seen it twice now. While almost technically accurate; radar signals travel at the speed of light, I’m not sure that the sign accurately communicated the message intended.
Then as I got close to the airport in Toronto another one said “yield to oncoming traffic”. I was on a on-ramp which made me really nervous, ’cause I was sure I was going the right way!
That ranks right up there with the on-road painted signs that are written upside down, like AHEAD STOP. Which reminds me of an XKCD comic.
