Ugh.

WSJ: Big Honkin' Horns Hit the Highway

Some SUV Owners Install
Loud, Costly Air Horns;
The Noise-Law Loophole

Jim Stevenson bought a Hummer H2 a few years ago because he liked its "Tonka Toy on steroids" look. Everything about it was macho -- except for the horn.

After a bunch of boys on a street corner signaled to him to honk, and were clearly disappointed, it was the last straw, says Mr. Stevenson, an Orlando, Fla., real-estate agent. "You have this big beast, and you hit the horn, and it sounds like Mike Tyson talking," he says. "It's truly embarrassing."

So Mr. Stevenson went out and installed an air horn in his SUV. The new horn is so loud, he says, that sometimes when he honks it, people applaud.
