Overlength limits vary depending on the type and the configuration of vehicle, but the overall maximum forward distance (i.e. the length from the front of the vehicle to the centre axis of the rear axle set) is , the overall maximum single vehicle length is (some buses can be longer), and the overall maximum combination length is . Loads must be indivisible, except when the vehicle is oversize itself where it can carry divisible loads as long as the divisible load fits within the standard load limits. Permits are not required for oversize vehicles which are under long, under high, and fit within a set combination of width and forward distance; but they must comply with certain rules regarding piloting, travel times and obstructions. United States In the United States, an oversize load is a vehicle and/or load that is wider than . Each individual state has different requirements regarding height and length (most states are 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 (i.e. an object which cannot be broken down into smaller pieces), although some states allow divisible loads to be granted permits. Signaling A pilot car driver may temporarily block traffic at intersections to ensure the safe passage of the truck. Hazards Oversize loads present a hazard to roadway structures as well as to road traffic. Because they exceed design clearances, there is a risk that such vehicles can hit bridges and other overhead structures. Over-height vehicle impacts are a frequent cause of damage to bridges, and truss bridges are particularly vulnerable, due to having critical support members over the roadway. An over-height load struck the overhead beams on the I-5 Skagit River bridge in 2013, which caused the bridge to collapse. Licensing Different countries have different approaches to licensing oversize/overweight loads. Licenses may be issued for a specific load, for a period of time, or to a specific company. In most jurisdictions, the permit specifies the exact route a vehicle must take, and includes clearance warnings. However, in some places, such as Washington state, drivers are responsible for choosing their own route. The carrier can choose to obtain the required permits
