Managed lanes
Some jurisdictions generally prohibit trucks from faster lanes on motorways, or from the express lanes in an express-local system. Some lanes have restrictions based on vehicle weight, for example to prevent overloading certain parts of a bridge. A small number of jurisdictions have truck-only lanes, intended to increase reliability of freight deliveries. Different lanes can also have different height restrictions, depending on the shape of overpasses.
