[7] In a specific country, the roads are built in a way that allows a vehicle with dimensions within the standard legal limits to safely (though not necessarily easily) drive and turn.

Special permits are issued by local authorities to allow a transporter to operate on a public road for a limited period and for a certain and given route.

A table of maximum dimensions and weight as well as best practices is available for European countries on the following industry resource site.

Each of these trucks can carry loads such as trams, energy transformers, construction machines, metallic structures or wooden boxes/crates.

[14] National Highways operates a system known as "Electronic Service Delivery for Abnormal Loads" (ESDAL) for the purpose of supporting notifications.

[18] In India, any load which protrudes the platform of the vehicle which is defined in CMVR 1989 is considered ODC (Over Dimensional Cargo).

Loads above 55 tons can only be moved on HMT (hydraulic modular trailer) and puller tractor combination, for which a nationalized permission must be obtained via MORTH (Ministry of Road Transport and Highways of India) portal with HMT payload of 18 ton per axle excluding the weight of the puller tractor.

[21] A pilot car driver may temporarily block traffic at intersections to ensure the safe passage of the truck.
