Utah drivers have a reputation for being the worst on the road. But is that title deserved or are we getting a bad rap? We sent News Specialist Nadine Wimmer out on the streets to find Utahns "Driving to Extremes."

We found many Utah drivers have their own interpretations of traffic laws. Put yourself to the test. When you approach a traffic light, and it turns yellow, do you stop or speed up? You're supposed to stop -- if you speed up, you know you're a Utah driver.

Here are the traffic laws, Utah style.

• Rule Number One
  The meaning of traffic signals: In most states, a green light means "go."
  In Utah, it means wait for drivers running the red light.

Time after time, we spotted cars blowing through yellow and red to crowd through the intersection.

• Utah Traffic Rule Number Two
  In most places, a turn signal means you are planning to turn.
  In Utah, it's an accessory -- optional on many vehicles.

Highway patrol troopers say this is the number one pet peeve on the road--drivers who simply refuse signal.

Trooper Steve Winward/U.H.P.: "THE LAW IS IF YOU'RE TRAVELING DOWN THE LANE, YOU HAVE TO GIVE SUFFICIENT NOTICE."

• Rule Number Three
  It's customary to merge into a lane where there is actually room to merge.
  In Utah, room is only a consideration.

• Rule Number four in Utah
  Drive as close to the car ahead of you as possible. If you don't somebody will get in front of you.

The law says stay back one car length for every 10 miles an hour. We tried....

"IF I STAY SIX CAR LENGTHS BEHIND SOMEONE ON THE FREEWAY WHAT WOULD HAPPEN TO ME? A: ABOUT FIVE CARS WOULD CHANGE LANES IN BETWEEN YOU."

• Rule Number Five
  Don't let another motorist merge onto the freeway. Close ranks with other cars -- it's called the Utah block.

"THEY DON'T CARE ABOUT ANYBODY ELSE, THEY'RE JUST LOOKING OUT FOR THEMSELVES."

The truth is, there are bad drivers everywhere -- so do Utahn's really stand out? We asked interstate truckers who drive the country and see it all.

Bob Willoughby/Interstate Trucker: "I'D SAY UTAH'S THE WORST."

Ed Guin/Interstate Trucker: "WITH THIS CONSTRUCTION HERE, THEY'VE GONE INSANE. THEY'LL CUT YOU OFF. RUN YOU OFF THE ROAD."

"WHICH STATE HAS THE WORST DRIVERS? A: WHICHEVER STATE HAS CONSTRUCTION. IT'S FAR BETTER IN L.A. THAN IT IS HERE."

"IT JUST SEEMS LIKE THESE PEOPLE HAVE GONE CRAZY."

"THEY'LL CUT YOU OFF IN A HEARTBEAT."
