The express lanes on Denver's highways are tolled

If you are new to driving around Denver, the painted lines on the highway carry rules worth knowing before you drift across them.

Several Front Range highways have express lanes running alongside the regular free lanes. These lanes are run by the state transportation department, CDOT, and its Colorado Transportation Investment Office. They charge a toll, and the price can change with traffic. Some allow carpools or transit to use them for less, but you usually need an eligible pass or transponder, and the lanes are enforced. Crossing a solid line to jump in or out can bring a ticket.

Why care: a driver who treats an express lane like a normal lane can get a toll bill or a fine. A new resident planning a commute should know which corridors have these lanes and how payment works before the first drive, not after.
