QuestionPrior tothe 20th century, freight was generally transported overland via trains and railroads.During this time, trains were essential, and they werehighlyefficient at moving large amounts of freight.But, they could only deliver that freight to urban centers for distribution by horse-drawn transport.Though there were several trucks throughout this time, theywere usedmore as space for advertising that for actual utility.At this time, the use of range for trucks was quite challenging.The use of electric engines, lack of paved rural roads, and small load capacities limited trucks to most short-haul urban routes.


The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection.It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball shouldbe mountedto the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers.Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle.This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).

QuestionIn 1999, The Simpsons episode Maximum Homerdrive aired. It featured Homer and Bart making a delivery for a truck driver named Red after he unexpectedly dies of 'food poisoning'.

QuestionAs most people have experienced, moving does involve having the appropriate materials.Some materials you might find at home or may be more resourceful to save money while others may choose to pay for everything.Either way materials such as boxes, paper, tape, and bubble wrap with which to pack box-able and/or protect fragile household goods. It is also used toconsolidatethe carrying and stacking on moving day. Self-service moving companies offer another viable option. It involves the person moving buying a space on one or more trailers or shipping containers. These containers are thenprofessionallydriven to the new location.

QuestionThroughout 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.

QuestionThe American Association of State Highway and Transportation Officials (AASHTO) conducted a series of tests.These tests were extensive field tests of roads and bridges to assess damages to the pavement.In particular they wanted to know how traffic contributes to the deterioration of pavement materials. These testsessentiallyled to the 1964 recommendation by AASHTO to Congress.The recommendation determined the gross weight limit for trucks tobe determined bya bridge formula table. This includes table based on axle lengths, instead of a state upper limit. By the time 1970 came around, there were over 18 million truck on America's roads.
