Vehicles, machinery and mixed fleets

Commercial motor fleets and mobile plant/equipment insurance

A clean schedule is useful, but the way each vehicle and machine operates matters just as much.

Commercial motor fleet insurance generally addresses registered business vehicles, while mobile plant/equipment insurance may address machinery used on worksites and roads. A business may need both, with separate terms for physical damage, third-party liability, road risk, working risk, hired plant, attachments, recovery and downtime. The vehicle and plant schedule, drivers and operators, locations and actual use are central to the review.

Classify every unit

Registered vehicles and mobile plant/equipment are connected but different

A mixed fleet can include passenger vehicles, utilities, vans, rigid trucks, trailers, forklifts, excavators, loaders, cranes, generators and specialist attachments. The policy needs to match how each item moves, works, is hired and is valued.

Common fleet categories and review questions
Fleet category What to describe Terms to check
Registered commercial vehicles Vehicle type, registration, value, radius, garaging, driver use, loads and modifications. Own damage, third-party property damage, towing, substitute vehicles, hire costs and driver restrictions.
Mobile plant and equipment Serial number, value, attachments, work performed, sites, transport method and operator controls. Road risk, working risk, overturning, recovery, debris removal, wet or dry hire, and damage while being transported.
Hired-in or hired-out plant Hire agreements, replacement values, duration, responsibility, operator arrangements and geographic use. Contractual liability, continuing hire charges, loss-of-hire, subrogation, damage waivers and exclusions.
Attachments, tools and cargo Which items are permanently fitted, interchangeable, carried, towed or supplied by another party. Whether the item belongs under motor, plant, portable assets, marine cargo or another policy section.

Road risk

When the unit is moving between jobs

Road use can involve collision, theft, third-party property damage, towing and recovery. Compulsory third-party personal injury insurance connected to registration is separate from cover for damage to the vehicle or other property.

Working risk

When the machine is doing the job

A plant item can cause damage while lifting, digging, grading, drilling, spraying or operating as a tool. Working-risk liability, overload, underground services, vibration and damage to the item being worked on can have specific exclusions or sublimits.

Preparing the submission

Motor and plant fleet insurance review checklist

Illustrative example

An excavator overturns on a worksite

The incident may involve damage to the machine, heavy recovery, damage to nearby property, continuing hire charges and project delay. Different policy sections and limits may apply. Cover depends on the insured use, operator, site, policy trigger and exclusions.

Important boundaries

A motor or plant policy does not cover every item nearby

Tools, cargo, contract works, underground services, mechanical failure and the machine's work product can require separate sections or policies. Wear and tear and maintenance are commonly outside accidental-damage cover.

Official Australian guidance

Insurance and safety obligations should be reviewed separately

Australian Government business guidance notes that compulsory third-party personal injury insurance is commonly linked to vehicle registration, while other motor insurance protects different interests. Safe Work Australia explains that plant is a broad safety category. Its guidance is about work health and safety, not the scope of any insurance policy.

Frequently asked questions

Commercial motor and plant fleet questions

What is commercial motor fleet insurance?

It is a commercial insurance arrangement for a business's vehicles, subject to the policy's vehicle schedule, permitted uses, drivers, geographic limits, limits, excesses and exclusions. Fleet eligibility and policy structure vary by insurer.

Is mobile plant covered by commercial motor insurance?

Not necessarily. Some arrangements can include selected registered or road-going plant, while other machinery needs a dedicated mobile plant section or policy. Road risk, working risk, physical damage and liability must each be checked.

What is the difference between road risk and working risk?

Road risk generally concerns the unit while travelling or used as a vehicle. Working risk concerns liability or damage arising while plant performs its function, such as lifting, digging or grading. Policy definitions and exclusions determine the actual distinction.

Can hired-in plant and dry or wet hire be covered?

Potentially, but ownership, contract terms, responsibility for operators, hire duration, replacement value and continuing hire charges must be disclosed. Dry hire without an operator and wet hire with an operator can create different exposures.

Does motor or plant insurance cover mechanical breakdown?

Accidental-damage cover does not automatically include internal mechanical or electrical breakdown, wear and tear or lack of maintenance. A separate machinery-breakdown section may be relevant, subject to its own terms.

What information is needed for a motor and plant fleet review?

Start with a complete schedule, values, registrations or serial numbers, attachments, use, radius, locations, drivers and operators, hire arrangements, security, maintenance and claims. Explain unusual work rather than relying on the equipment name alone.

Broking For You review focus

Build one schedule, then test each exposure

We separate vehicles, plant, attachments and hired equipment, then connect each item to its use, operator, value, location, recovery exposure and contractual responsibilities. That makes the comparison of available terms more useful than a list of registrations alone.

A clearer fleet submission can help an insurer understand the risk. It does not guarantee acceptance, a particular premium, broader cover or payment of a claim.
