Payload, Axle Loads and Stability
Calculate available payload and assess gross, train and axle limits together with centre of gravity and load distribution.
How to prepare for Part 2 case studies
Combine vehicle, driver, load, route, site, time and document facts before selecting the safest lawful action; always carry each decision forward through the rest of the narrative.
Core concepts
Concept 1
Calculate available payload and assess gross, train and axle limits together with centre of gravity and load distribution.
Exam cue: Read the complete case narrative before choosing the rule or action.
Concept 2
Use plated limits and supplied weights to decide whether a proposed load or redistribution is lawful and stable.
Exam cue: Use plated limits and supplied weights to decide whether a proposed load or redistribution is lawful and stable.
Concept 3
Being below gross weight does not prove that every axle is within limit or that the load is stable.
Exam cue: Check how the decision affects the remaining journey, people, vehicle, load and records.
Risk pitfalls and guardrails
Checking only total vehicle weight and overlooking an overloaded axle.
Guardrail: Do not answer from one familiar phrase while ignoring another fact in the linked narrative.
Answering from a remembered rule before checking all supplied facts.
Guardrail: Do not answer from one familiar phrase while ignoring another fact in the linked narrative.
Treating the internal study allocation as an official topic weighting.
Guardrail: Do not answer from one familiar phrase while ignoring another fact in the linked narrative.
Memory anchors
Gross Plus Axles
Check the total and each axle limit.
Payload Is Available Mass
Start with the legal vehicle limit and subtract actual operating mass.
Low and Even Wins
A lower, well-distributed centre of gravity improves stability.
Reweigh After Change
Loading or redistribution changes the legal and stability picture.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
In the CityBuild case, the gross weight is within the plated limit but the rear axle exceeds its plated figure. Is the vehicle legally loaded?
In the Moorland case, several heavy paper reels are placed high and to one side. What is the main handling concern?
