Frequently Asked Questions (FAQ)
Express Lanes are new lanes built in addition to any existing general-purpose lanes to provide drivers the choice of a more reliable trip by paying a toll. Toll prices are set to manage traffic and have just the right number of vehicles in the lane to provide reliable, shorter travel time.
On some Express Lanes, tolls can change in price depending on the level of congestion. As traffic increases, the toll price goes up to make sure the lane always remains a free-flowing alternative for travelers. Conversely, the toll price will decrease when there is less traffic in the lane. Drivers will always be charged the amount on the overhead signage when they enter the Express Lanes.
Express Lanes increase roadway capacity and help manage congestion on Colorado's highways. They offer choice by allowing drivers to ride the bus, carpool, or pay a toll and use as a solo driver as an alternative to the free general-purpose lanes.
Express Lanes work to move more people rather than move more cars. By presenting choices, Express Lanes reduce delays, help manage congestion and keep travel times reliable for motorists in all the lanes.
The Express Lanes Safety and Toll Enforcement Program (STEP) is managed by the Colorado Transportation Investment Office (CTIO), the government-owned business within CDOT that oversees Colorado’s Express Lanes. The program encourages safe driving on CTIO’s network of Express Lanes by using sophisticated roadside technology to enforce Express Lane rules. Violators identified by this technology will be issued a civil penalty via mail based on the registered address of the vehicle’s license plate. Violations not paid within 20 days of issuance will increase to a $150 civil penalty.
STEP is meant to encourage drivers to use the Express Lanes safely and correctly and prevent dangerous behaviors such as weaving in and out of the Express Lanes. Safety for all motorists along these corridors is the top priority of this enforcement.
