A MnPASS electronic transponder is required in order to pay tolls because there are no tollbooths on the roadway. The price varies depending on the time of day and flow of traffic. Lone drivers were previously allowed to use the express lanes in off-peak times, but this is no longer allowed under the new system unless the sign says the cost is "OPEN," meaning free. The decision to make the non-reversible lanes free on off-hours was reached due to complaints about essentially making a four-lane freeway in an area that even on off-hours sorely needed six. Toll rates are expected to generally fall between $1 and $4, with a potential maximum of $8. Off-hours are charged as $0.25 on the reversible lanes and free on the one-way lanes. The white line-separated and reversible expressway sections are priced separately. The lanes are still open free to buses, motorcycles, and cars with 2 or more persons, no matter the time of day, and such vehicles do not require transponders to use the lanes.
