They careen through traffic, speed down emergency lanes, and create havoc on our highways. They're dangerous drivers and they may get worse with construction. News Specialist Craig Wall joins us now live from 9th west and south temple: How bad are these drivers expected to get?

Well, police hope our roadways won't become Los Angeles' ten years ago when aggravated drivers retaliated with guns instead of horns. But you can bet we'll have more to worry about with construction

Construction is already creating a class of drivers who throw safety out the window as they race to their destination.

((SGT. DAN CATLIN, UHP: "YOU HOPE FOR THE BEST, BUT YOU PLAN FOR THE WORST."))

And the worst is yet to come. We spent several days in the thick of things and the preview is enough to cause alarm. We saw frustrated drivers refusing to obey the law because they didn't want to wait in traffic. We watched as they peeled through parking lots to cut a few minutes off their commute. And cringed as others veered out of congestion, into the path of oncoming cars because the delays became too much to deal with. And it gets worse.

((SGT. DAN CATLIN, UHP: "THEY'LL INTENTIONALLY HIT OTHER PEOPLE WITH THEIR VEHICLE, WE RESPOND TO FIGHTS IN THE MIDDLE OF THE INTERSTATE."))

In the movie L-A story Hollywood laughs at California's freeway shootings. But victims say there's nothing funny about the real thing.

((IWONA BEDNARCZYK, SHOOTING VICTIM: "WE ALL KINDA LOOKED IN THEIR DIRECTION AND WE SAW TWO GUNS POINTED AT US FROM THE DRIVER'S WINDOW, THEN WE ALL DUCKED, THEN THERE WAS A SHOT RIGHT THROUGH THE WINDOW."))

What prompted this shooting? Honking at a discourteous driver.

((JEFF JOLEY, HIGHWAY SHOOTING VICTIM: "I COULDN'T BELIEVE IT, I THOUGHT WE WERE DEAD."))

((CRAIG WALL REPORTING: "AUTHORITIES PLEAD WITH DRIVERS TO BE PATIENT THROUGH ALL OF THIS, BUT THEY KNOW THE LONG LINES WILL BREED SHORT TEMPERS."))

That's why, at least in highway construction zones you'll see troopers with lights flashing.... and you might not see dangerous drivers.

((SGT. DAN CATLIN, UHP: "THE PEOPLE WILL TEND NOT TO DRIVE THAT WAY WHEN THERE'S A HIGHWAY PATROL CAR THERE."))

The same is true when people saw our camera--notice the courteous merging. But as soon as we took up a hidden position courtesy gave way to craziness. And police expect reports of cut-offs, rammings or other violence will become more common as roadways become more constricted by construction. And here's a warning.

((SGT. DAN CATLIN, UHP: "IF YOU RAM SOMEONE WITH YOUR CAR THAT'S AN AGGRAVATED ASSAULT THAT'S THE SAME AS IF YOU TAKE A BAT OUT AND HIT HIM."))

And getting revenge like that for getting cut off, or being on the receiving end of a hand gesture could turn the trip home into a trip to court and even prison.

Here's fuel for thought: the few seconds you'll save cutting in front of someone, or sneaking through a parking lot, will it be worth it if you hit someone, or get shot?

Are there particular areas where traffic and tempers are expected to be the worst? Just about anywhere where construction constricts traffic and that will soon mean more highways and main roads. As Sgt. Dan Catlin put it, we're gonna have "worst" areas all over the place.
