25-question written theory test, pass standard 80% (20 of 25). Answered in the candidate’s own handwriting, covering:
Law, responsibilities and competence
Pre-use checks and defect reporting
ROPS, FOPS and seat belt use
Safe loading and load distribution
Gradients, soft ground and tipping points
Tipping safely and stuck loads
Visibility, reversing and pedestrian safety
Emergency procedures and site haul roads
The following are safety-critical and must be answered correctly regardless of the overall score:
Seat belt use with ROPS
Never travelling across a slope side-on
Stop blocks and safe distance from a tip edge
Load distribution within rated capacity
Reversing under observation
Practical assessment
Structured exercises, each marked against observed performance criteria. Every criterion must reach competent; any dangerous act terminates the assessment.
Pre-use inspection including ROPS, seat belt, brakes, steering, hydraulics and tyres
Positioning correctly for loading by an excavator and checking load distribution
Travelling laden and unladen: gradients, rough and soft ground, confined areas
Reversing with all-round observation and use of a marshal where the view is restricted
Approaching and discharging at a tipping point with stop blocks and safe edge distance
Dealing safely with a load that does not discharge
Parking, shutdown, isolation and post-operational checks
The assessor deemed Fred Bloggs competent within the stated scope, and the qualification was awarded in August 2026.
The legal position
No UK government body issues a licence to operate a dumper, and no statute requires one. The duty to train and assess competence sits with the employer, under the Health and Safety at Work etc. Act 1974 section 2(2)(c) and the Provision and Use of Work Equipment Regulations 1998 regulation 9.
The controls that matter are the roll-over protective structure (ROPS) and the seat belt. Overturning, and the operator being thrown from the seat, is the dominant fatal mechanism. PUWER 1998 applies, and HSE guidance HSG144, Safe use of vehicles on construction sites, sets out the wider standard for site vehicle use.
The full site evidence statement sets out the basis of the qualification, the assessment decision and the audit trail, for presentation to site management and health and safety personnel.
The full site evidence statement is issued with the operator’s pack.
Site-specific familiarisation and the employer’s written authorisation to operate are separate and remain the employer’s responsibility.
