Trailer stability can be defined as the tendency of a trailer to dissipate side-to-side motion. The initial motion may be caused by aerodynamic forces, such as from a cross wind or a passing vehicle. One common criterion for stability is the center of mass location with respect to the wheels, which can usually be detected by tongue weight. If the center of mass of the trailer is behind its wheels, therefore having a negative tongue weight, the trailer will likely be unstable. Another parameter which is less commonly a factor is the trailer moment of inertia. Even if the center of mass is forward of the wheels, a trailer with a long load, and thus large moment of inertia, may be unstable.

A semi-trailer is almost exactly what it sounds like, it is a trailer without a front axle.Proportionally, its weightis supported bytwo factors. The weight falls upon a road tractor or by a detachable front axle assembly, known as a dolly. Generally, a semi-traileris equippedwith legs, known in the industry as "landing gear". This means it canbe loweredto support it when itis uncoupled. In the United States, a trailer may not exceed a length of 57 ft (17.37 m) on interstate highways.However, it is possible to link two smaller trailers together to reach a length of 63 ft (19.20 m).

A business route (occasionally city route) in the United States and Canada is a short special route connected to a parent numbered highway at its beginning, then routed through the central business district of a nearby city or town, and finally reconnecting with the same parent numbered highway again at its end.

Throughout the United States, bypass routes are a special type of route mostcommonlyused on an alternative routing of a highway around a town.Specificallywhen the main route of the highway goes through the town.Originally, these routeswere designatedas "truck routes" as a means to divert trucking traffic away from towns.However, this name was later changed by AASHTO in 1959 to what we now call a "bypass".Many "truck routes" continue to remain regardless that the mainline of the highway prohibits trucks.

A Ministry of Transport (or) Transportationis responsible fortransportation within a country. Administration usually falls upon the Minister for Transport.The term may alsobe appliedto the departments or other government agencies administering transport in a nation who do not use ministers.There are various and vast responsibilities for agencies to oversee such as road safety. Others may include civil aviation, maritime transport, rail transport and so on. They continue to develop government transportation policy and organize public transit. All while trying to maintain and construct infrastructural projects. Some ministries haveadditionalresponsibilities in related policy areas as mentioned above.
