From page 98... ... 98 A P P E N D I X A Maximum Permitted Axle Weights The maximum permitted axle weight specified by states along an OSOW route affects the configuration of overweight loads and the multi-state movement of those loads. When planning multi-state shipments, carriers must identify the state with the lowest maximum axle weight along their route to select and configure a trailer that is compliant in each state along the route.

From page 99... ... Inventory of OSOW Truck Permitting Differences 99 Tandem Axle The state-by-state variation in maximum allowable weights for tandem axles is larger than single axles with very few clusters of states with contiguous values. Similar to single axles, a number of states have a case-by-case calculation for the maximum weight on a tandem axle (Figure A-4) Read the entire page →

From page 115... ... Inventory of OSOW Truck Permitting Differences 115 Width First Civilian Escort The most noticeable pattern in the width threshold for the first civilian escort is that there are three major clusters of states: one extends from Idaho to Illinois, the other encompasses the states from Indiana to the East Coast, and the final includes the remainder of the states in the Southern Plains and the states in the Pacific Northwest (Figure A-19) Read the entire page →
From page 116... ... 116 Multi-State, Multimodal, Oversize/Overweight Transportation Plains states and from Maryland to South Carolina remain as a cluster of states with similar regulations.

From page 121... ... Inventory of OSOW Truck Permitting Differences 121 State Police Requirements Police escorts are required when states believe that civilian escorts are insufficient to ensure that a load moves safely through the jurisdiction. If required, a police escort procurement is an expensive element of an OSOW move, driven in part by the variability in regulations governing police hours of duty and jurisdiction.

From page 138... ... 138 Multi-State, Multimodal, Oversize/Overweight Transportation Civilian escort certification is another issue for OSOW carriers to consider when planning a move.

Inventory of OSOW Truck Permitting Differences 145 variety of reasons, such as a piece of equipment being repaired, replacement of equipment, construction along the route, the shipper miscalculating the weight or size of the load, etc. In states that allow revisions, the carrier can generally make adjustments to the permit and remain on schedule.

From page 147... ... Inventory of OSOW Truck Permitting Differences 147 loads have a single point where clearance is an issue, whereas rectangular loads have to worry about corner clearances due to the angle of the road or overheard structures. Minimum clearance restrictions can be avoided by taking off ramps to detour over the structure rather than under it. Read the entire page →
From page 148... ... 148 Multi-State, Multimodal, Oversize/Overweight Transportation Impact of Minimum Clearance on OSOW Permitting When minimum clearance requirements are not met and no alternate route is available, carriers and permitting offices work closely to find a safe solution. One example occurred on a roadway that pitched the width of the two lanes, giving one lane greater distance between the roadway and the overhead structure. Read the entire page →
From page 149... ... Inventory of OSOW Truck Permitting Differences 149 Impact of Frost Restrictions on OSOW Planning and Permitting Frost restrictions vary by state, requiring OSOW carriers to carefully plan moves to account for state-by-state differences.
