AASHTO Design Vehicles
(OP)
Does anyone know what a WB50, WB60 and WB62 really are? What type of vehicle are they and when are they typically used? And vice-versa, what design vehicle is typical of an automobile carrier, gasoline container truck, delivery truck to big box retail store, etc?





RE: AASHTO Design Vehicles
A designer would typically use a copy of a turning movement diagram on a clear sheet to overlay the plans to check for conflicts. There are tables which give minimum turning radii for various vehicles, but this isn't always enough to design from.
RE: AASHTO Design Vehicles
The templates show what most vehicles in that class are capable of, with no regard for the skill (or lack of it) of the driver. It's good practice to allow at least a 3 ft (1 m) margin of error. For tandems and triples, I'd make it even more.

A stinger-steered vehicle would probably off-track less than a conventional semitrailer of the same length.
