A scale ticket says 80,000 pounds. That number alone does not tell a dispatcher whether the truck is ready for its route. The useful question is whether the carrier has reviewed the relevant axle weights, group spacings, equipment limits, and route restrictions. Use these six checks to organize that handoff; the carrier's qualified reviewer makes the operating decision.
1. Match the ticket to the actual departure configuration
Record the tractor and trailer identifiers, ticket time, load reference, and configuration when weighed. Ask whether freight, fuel, equipment, or axle positions changed afterward. Keep the earlier ticket when requesting an updated one so the reviewer can follow the change. A familiar truck number is insufficient if the trailer or load arrangement differs.
2. Read the axle-group lines before the total
FHWA's bridge-weight guidance distinguishes single-axle, tandem-axle, and gross limits. A satisfactory total does not establish that each component meets its applicable limit. Copy the ticket's actual labels rather than renaming a group from memory. If a reading combines axles the reviewer needs separately, flag that missing detail. FHWA Bridge Formula Weights.
3. Record spacing for the groups being reviewed
The federal bridge formula considers both axle count and the distance between the group's outer axles. Do not substitute trailer length or wheelbase unless it is the measurement actually required for that group. Have the carrier identify the consecutive axle groups to check and supply their measurements. FHWA's examples show why an internal group can require attention even when the whole vehicle passes its formula check. FHWA explanation and examples.
4. Attach the route and the applicable limit basis
The FHWA pamphlet addresses the Interstate system and identifies exceptions; it is not clearance for every road. Ask the reviewer to identify the route-specific rules, postings, permits where applicable, and equipment restrictions used in the decision. Record unresolved route segments explicitly. “Federal gross limit checked” should never become shorthand for “every restriction reviewed.”
5. Give every correction an owner and a new record
If a discrepancy appears, ask the carrier to define the correction and the verification it requires. Dispatch should not prescribe a slider movement from a gross total. Record who handles loading changes, who confirms the revised configuration, and who obtains any required reweigh. Replace an ambiguous note such as “weight fixed” with the new evidence and reviewer's decision.
6. Close the handoff with evidence, scope, and approval
Make the departure record readable to the next shift. Link the final ticket and configuration, list the checks completed, and name the reviewer. Keep an unresolved item open until that reviewer closes it. A worksheet supports communication; it does not issue a permit or replace the carrier's compliance process.

Worked example: a correct total with an open group issue
Hypothetical ticket: steer 12,000 pounds, drives 33,000, trailer group 35,000. The total is 80,000. Assume the carrier's reviewer has confirmed a 34,000-pound limit for that trailer group on this movement. The group is 1,000 pounds over that confirmed limit even though the total is at 80,000. Dispatch records the discrepancy and requests the carrier's correction and recheck. The example does not establish that the other axle groups, spacing, route, or equipment are acceptable.
