TRUCK INSURANCE CASE STUDY

Owner-Driver Prime Mover, Renewal Remarketed at Roughly Half the Premium

A single-truck operator hauling containers in North Queensland came to us uninsured. We placed the prime mover with one insurer in year one, then took the renewal back to market and moved it for a premium around half the first year's, on that year's facts.

01

THE SITUATION

A North Queensland owner-driver came to Tank Insurance with a single prime mover, an older European cab-over with low kilometres, towing trailers for a regional transport operator. The work was general cargo in shipping containers, and the trailer belonged to a third party, so cover for a trailer in the operator's control mattered as much as cover for the truck.

The truck had been uninsured for several years. That gap, plus a one-person business with modest turnover, narrowed the field before a single quote was requested.

02

OUR APPROACH

In year one we approached several commercial motor markets with the truck, the work and the trailer arrangement described accurately.

  • Several insurers declined on vehicle type or on the non-owned trailer, so the risk was placed with a specialist heavy motor insurer at a premium of around $9,300.
  • At renewal we did not roll the policy over. After twelve months of insured, claim-free operation the renewal submission set out the current operation: containers with a small proportion of goods the insurers treated as dangerous goods (dry ice), and a trailer-in-control sum insured of $10,000.
  • Three insurers quoted the renewal. The incumbent's renewal terms were referred and accepted with a loading for the dangerous goods component. A second heavy motor insurer referred the risk, accepted it, and came back at roughly half the incumbent's price. A third sat between the two.

The renewal was moved to the lower-priced insurer, with the trailer-in-control cover and the dangerous goods disclosure carried across.

03

THE CHALLENGES

The first-year placement was about finding any insurer that would accept a truck with a multi-year insurance gap and a trailer the client didn't own. Price was secondary to getting the truck insured at all.

The renewal was a different problem. The dangerous goods component, small as it was, triggered underwriter referrals, and the quotes only compared fairly once each was on the same trailer-in-control basis with the dry ice disclosed.

04

THE OUTCOME

The prime mover was renewed with a specialist heavy motor insurer at a premium of approximately $4,400, down from around $9,300 the year before.

Final Solution: Commercial motor on the prime mover renewed at around $4,400 a year, with trailer-in-control cover of $10,000 and the dangerous goods exposure disclosed and accepted.

Most of the saving came from marketing the renewal rather than rolling it over. The incumbent's own renewal offer was lower than year one, reflecting the claim-free year, but a second insurer priced the same disclosed risk at roughly half.

This case records one historical outcome; current insurer appetite, premium, timing and terms depend on the complete risk at the time of application.

OWNER-DRIVER QUESTIONS

What this placement answers for other owner-drivers

How much does insurance cost for a prime mover and trailer?
It is individually rated, so there is no list price. In this placement a single older prime mover hauling containers in North Queensland cost around $9,300 in year one, when the operator had a multi-year insurance gap, and around $4,400 at renewal after twelve months of claim-free cover and a remarketed renewal. Vehicle value, radius, goods carried, driver history, claims and whether the trailer is owned or in your control all move the number.
Can I insure a prime mover if I have not had insurance for several years?
Some insurers will decline on the gap or on the vehicle type, and others will quote it with the history disclosed. In this case several insurers declined in year one and a specialist heavy motor insurer accepted the risk. Disclose the gap rather than leaving it blank, because non-disclosure is a bigger problem than the gap itself.
Does my truck insurance cover a trailer I do not own?
Not automatically. A trailer that belongs to someone else but is attached to your prime mover usually needs a trailer-in-control extension with its own sum insured. This operator carried $10,000 of trailer-in-control cover on a third-party trailer. Check the wording, because some insurers exclude non-owned trailers outright.
Should an owner-driver remarket the renewal every year?
It is worth testing, particularly after a year that changes the risk: a claim-free period, a new contract, different goods or a new radius. Here the renewal was marketed to three insurers and moved, with the premium roughly halved. Rolling over would have left the lower price untested.
Does carrying a small amount of dangerous goods change prime mover insurance?
Yes. Even a small proportion, in this case dry ice in containers, triggered underwriter referrals and a loading on one of the quotes. Declare it, because an undisclosed dangerous goods load can affect a claim.
