Dumping, Compaction and Agricultural Plant
Loaded travel, tipping edges, body position, compaction patterns, articulation and towed equipment.
How to prepare for a CPCS category Theory Test
Learn the operator's safe decision sequence, connect it to the current category learning outcomes and practise explaining why the manufacturer, task and site controls apply.
Core concepts
Concept 1
Loads are secure and within capacity, with speed and route matched to the machine and ground.
Exam cue: Separate travel stability from tipping stability.
Concept 2
Tipping requires stable, level support, safe edge control and confirmation that the body or skip can rise clear.
Exam cue: Lower and secure bodies or implements before travel.
Concept 3
Compaction and tractor operations manage slopes, articulation, rollover risk, attachments and bystanders.
Risk pitfalls and guardrails
Tipping while the machine is cross-slope.
Guardrail: Do not replace a manufacturer limit, competent plan, physical control or authorised decision with experience or memorised wording.
Travelling beneath a raised body.
Guardrail: Do not replace a manufacturer limit, competent plan, physical control or authorised decision with experience or memorised wording.

Lower and secure before moving.
Load Changes Braking
Allow for greater stopping distance.
Articulation Has a Zone
