Prime Mover & B-Double Insurance Queensland

Specialist Insurance for Linehaul & Heavy Combination Operators

Prime movers and B-Doubles represent some of the highest-value and highest-exposure vehicles operating on Queensland roads. From long-haul freight between Brisbane and Cairns to regional heavy combination work through Toowoomba and Central Queensland, these vehicles face complex operational and financial risks.

At Design Cover Insurance Brokers, we arrange tailored Prime Mover and B-Double Insurance in Queensland for owner-drivers, subcontractors and transport businesses operating heavy combinations.

Whether you operate a single prime mover out of the Sunshine Coast or manage multiple heavy combinations servicing interstate routes, we structure insurance programs designed to protect your asset, your contracts and your income.

Why Prime Mover Insurance Is Different From Standard Truck Insurance

Prime movers and B-Doubles carry significantly greater exposure than rigid trucks.

Key differences include:

Higher insured values (often $250,000–$400,000+ per unit)
Multi-trailer configurations
Long-distance fatigue risk
Interstate operations
Higher third-party property damage potential
Greater cargo aggregation exposure
Increased likelihood of jack-knife or roll-over incidents

Because of these exposures, heavy combination insurance must be structured carefully. A generic commercial motor policy is rarely sufficient.

Who Needs Prime Mover & B-Double Insurance?

We work with:

Linehaul operators
B-Double operators
Road train contractors
Interstate freight businesses
Subcontract drivers working under major carriers
Fleet operators with heavy combinations
Refrigerated heavy combination operators
Bulk freight and tanker operators

If your business depends on a prime mover to generate revenue, correct structuring is critical.

What Does Prime Mover Insurance Cover?

A properly structured policy may include:

Comprehensive Vehicle Cover

Protection for:

Collision and accidental damage
Jack-knife incidents
Rollover
Fire
Theft
Storm and hail damage
Flood (subject to policy terms)
Malicious damage

Given Queensland’s severe weather — particularly in South East Queensland and North Queensland — storm exposure must be clearly addressed.

Trailer & Combination Cover

For B-Doubles and heavy combinations, cover must extend to:

Lead and rear trailers
Dog trailers
Skeletal trailers
Refrigerated trailers
Tanker combinations

Incorrect trailer valuation is one of the most common gaps in heavy combination policies.

Downtime / Loss of Income Cover

When a prime mover is off the road, revenue stops — but finance repayments, fuel accounts and overheads continue.

Downtime cover can provide:

Daily income payments
Temporary replacement funding
Support during extended repair periods
Protection against major collision delays

For many owner-drivers in Queensland, downtime cover is more financially important than repair cost cover.

Hire Vehicle After Accident

Heavy combinations are not easily replaced. Access to hire vehicle funding can be critical for maintaining contracts.

Third-Party Property Damage

Heavy combinations create higher third-party exposure.

Examples include:

Multi-vehicle highway collisions
Infrastructure damage
Delivery-site structural damage
Bridge strike incidents
Fuel spill liability

Given the weight and size of B-Doubles, third-party claims can be substantial.

Carrier’s Liability & Marine Transit (Critical for Linehaul Operators)

Many prime mover operators assume vehicle cover protects cargo — it does not.

You may require:

Carrier’s Liability Insurance

Protects you where legally liable under freight contracts.

Marine Transit Insurance

Covers damage to goods being transported.

If you operate between Brisbane, Rockhampton, Mackay, Townsville and Cairns, long-haul cargo exposure can be significant — especially with refrigerated or high-value freight.

Common Prime Mover & B-Double Claims in Queensland

Heavy combination claims frequently include:

Jack-knife accidents during wet conditions
Rollover incidents on regional routes
Hail damage in South East Queensland
Cyclone-related damage in North Queensland
Wildlife collisions inland
Trailer theft
Refrigeration breakdown causing cargo spoilage
Multi-party third-party property damage claims
Driver fatigue-related incidents

Without correct structuring, exclusions and sub-limits can create major financial shortfalls.

Operating Across Queensland – Unique Risk Considerations

Prime movers operating in Queensland face diverse geography:

South East Queensland (Brisbane, Gold Coast, Sunshine Coast)

High traffic congestion
Dense delivery environments
Increased accident frequency
Severe hail exposure

Darling Downs & Toowoomba

Agricultural freight exposure
Heavy vehicle volumes
Livestock and bulk haulage risks

Central & North Queensland (Rockhampton, Mackay, Townsville, Cairns)

Cyclone exposure
Long-haul fatigue risk
Remote highway conditions
Wildlife collision risk
Limited immediate repair access

Insurance programs must reflect operating radius and geographic exposure.

What Affects Prime Mover Insurance Premiums?

Insurers assess:

Vehicle value and specification
Age and experience of drivers
Claims history
Freight type (general, refrigerated, hazardous)
Interstate vs intrastate operation
Combination type (single trailer vs B-Double)
Overnight parking security
Excess selection
Years in business
Maintenance procedures

Risk presentation is critical. Well-structured submissions can materially impact premium outcomes.

The Risk of Underinsurance in Heavy Combinations

Common underinsurance issues include:

Outdated vehicle values
Inadequate trailer limits
No downtime cover
No carrier’s liability
Inadequate third-party property damage limits
Failure to disclose interstate operation
Incorrect aggregation limits for cargo

Heavy combination operators cannot afford coverage gaps.

Fleet Considerations for Growing Operators

If you operate multiple prime movers, transitioning to a fleet structure may provide:

Consolidated renewals
Administrative efficiency
Flexible additions/removals
Long-term premium stabilisation strategies
Claims experience rating benefits

We assist growing transport businesses in Queensland with structured fleet transitions.

Contractual Insurance Requirements

Major freight contracts often require:

Minimum liability limits
Specific endorsements
Evidence of marine transit cover
Carrier’s liability compliance
Subcontractor coverage arrangements

We review your agreements to ensure your policy structure aligns with your contractual obligations.
