Transporting Oversized Load

The legal dimensions and weights vary between countries and regions within a country. A vehicle which exceeds the legal dimensions usually requires a special permit which requires extra fees to be paid in order for the oversize/overweight vehicle to legally travel on the roadways. The permit usually specifies a route the load must follow as well as the dates and times during which the load may travel.
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. Roads that do not allow large vehicles may be marked with the traffic signs. These may include per-axle load, height, width, or overall length limits.
In the United States an oversize load is a vehicle and/or load that is wider than 8' 6". Each individual state has different requirements regarding height and length (most states are 13' 6" tall), and a driver must purchase a permit for each state he/she will be traveling through. In many states, a load must be considered "nondivisible" to qualify for a permit (e.g., an object which cannot be broken down into smaller pieces), although some states allow divisible loads to be granted permits.
