Dedicated lanes result in mixing non-stop traffic into an often congested area designed for vehicles waiting in queues to pay the designated toll. Dedicated lanes within a conventional plaza should be designed to avoid giving a user the impression high-speed travel is allowed in these lanes.

Even though the other criteria enumerated above would be met, multiple adjacent lanes should be treated as express lanes, because of the appearance as a higher grade of non-stop toll operations.
