I think it's a great idea, and the signs can be made of quite cheap material because you really don't want them to stay in place too long, do you. IIn order to stay effective you have to change them a lot so people will want to read them, although of course there's the chance they might like them so much they start laughing, drive right through, and crash into somebody. But it is a great idea.

I wonder if somebody will start hiring gag writers for these if the idea takes off. Older readers can remember the Burma Shave signs.

To Linda- if the cost of an extra sign or two can reduce the number of accidents then it will be saving your tax dollars in the long run. There will be fewer rescue teams going to accidents and fewer police officers working those accidents.

if it saves your life lady, who cares how much it costs!

tess, tokyo,

I don't really want my tax dollars spent this way. How much does one sign cost, I wonder......
