what ahead?

Like, ZOMBIES AHEAD wouldn't work (obviously) so you'd need something scary; but at the same time, you wouldn't to confuse people onto an unsafe path.
I decided on, "DO NOT PROCEED, GUNMEN AT LARGE," and I would try to divert cars off the freeway. But still, there has to be a more effective message. THOUGHTS WELCOME!
ps: good post, Dan :)
