Transporting Oversized Load

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.
Typically, the edges of any oversize load must be marked to make them visible to drivers. during daytime the required marking is usually red flags, and during night white or yellow lights may be used. The hauling vehicle must have at least one flashing amber light in the front and back. Signs (yellow with black border in the United States, red and white diagonal stripes in the EU, and red and white vertical stripes in Canada), saying "Oversize load" must be put in the front and back of the vehicle.
