LANE HOGS ANNOY TROOPERS, TOO

Hogging the left passing lane of major highways is illegal and often leads to wrecks, the Colorado State Patrol says.

"Left lane campers’ aren’t aware of their impact on traffic flow and how it can trigger aggressive driving,” Colonel Matthew C. Packard, state patrol chief, said.

He advises drivers encountering a lefty to “pack a little patience and don’t risk your life ... frustrated drivers frequently create a domino effect for congestion."
