Some drivers are going to outrageous lengths to avoid paying tolls. To see how people are cheating the tolls, we hit the road with the Florida Highway Patrol. Within a few minutes Trooper Luis Tejera spotted a dump truck with a license plate smudged with grease. Tejera called in the plate number and discovered the driver has paid only three tolls in three months. Another man's open tailgate blocked his license plate from cameras. The trooper says it's a common trick he sees all the time.
