Warning other motorists of speed traps?

Question

Wondering how many other places in the States do people warn each other about speed traps by flashing thier headlights at oncoming traffic. I cant even count the times that it has saved me from getting a ticket ; ) I try to return the favor as much as possible.

Answer 1

We do the same in Australia including truckies warn over their two way radios butits an uwritten law that booze buses are not warned .~~

Answer 2

Be careful not to use your actual headlamp switch to do this, it also flashes your taillamps. I use the passing light on the signal switch when you pull it back, it usually flashes your high beams only.
