Colorado Left-Lane Law

Starting next week, travelers in Colorado need to be aware of a new law that forbids driving in the left lane of a multi-lane highway except when passing. If ticketed (I've a feeling the troopers are rubbing their palms together in anticipation), one can expect a $35 fine, $6.20 surcharge, and three points against the driving record.

Ostensibly, the law will prevent congestion and reduce road rage. Also, according to State Patrol Trooper Sara Shipley, Colorado has citizens that intentionally drive slow in the fast lane to prevent others from speeding. Frankly, of all the stupid things people do, being a vigilante traffic cop is a new one on me.

Lastly, could someone tell me why a traffic fine has a surcharge?
