Who it serves
Overview
Great West Casualty Company is an insurance carrier (underwriter) that specializes in trucking. It is part of Old Republic International Corporation and now presents itself online as "Great West, An Old Republic Company." The company is based in South Sioux City, Nebraska, and its site says it has been serving truckers since 1956.
Great West writes coverage for trucking operations described on its site as ranging "from one truck to 1,000." Beyond the policies themselves, it puts a lot of weight on safety and risk control, claims service and driver recognition programs. Note that the older gwccnet.com address now redirects to orgreatwest.com.

Services
Great West's product lineup covers most of what a motor carrier needs. Commercial auto liability protects against injury and damage claims from third parties. Physical damage coverage includes options such as comprehensive, lease or financed value, rental reimbursement, trailer interchange and motor carrier reimbursement. Cargo insurance protects the freight being hauled.
The company also offers general liability, workers compensation (including occupational accident options and a New York specific page), excess limits, and owner-operator products that include equipment coverage and non-trucking use. A specialty coverages section addresses bulk commodity carriers, freight brokers and freight forwarders.
For larger operations, Great West offers risk financing options including captives, large deductible retention programs and guaranteed cost programs.
On the service side, its Safety and Risk Control Services team provides resources aimed at reducing accidents. It runs a Motor Carrier Recognition program with company and driver safety awards, offers injury prevention tips for truckers, and maintains a learning library. A mobile app lets insureds file and view claims, print ID cards and review driver and equipment details.
Who it is for
Great West is a fit for motor carriers of almost any size, from single-truck owner-operators to large fleets. Its owner-operator products serve drivers who need equipment coverage and non-trucking liability, while its risk financing options are aimed at larger carriers that want to retain more of their own risk.
The specialty coverages section means freight brokers and freight forwarders can also look here, although brokers will want to confirm the exact contingent and broker liability forms available. The company says it provides coverage in 46 states and insures more than 60,000 trucking companies.
How working with them works
Great West sells through a network of independent agencies. Its about page says it partners with more than 200 independent agencies that specialize in truck insurance. The website also has a quote request form for trucking insurance, which routes prospects toward that process.
The company operates from five U.S. locations: Arlington, Texas; Bloomington, Indiana; Boise, Idaho; Knoxville, Tennessee; and South Sioux City, Nebraska.
Claims service is described as available 24/7/365, with a dedicated contact after an accident. Drivers and fleets can report claims through the claims services page or the mobile app. Pricing is not published and depends on underwriting.
Questions to ask before you sign
Ask your agent to list every coverage on the proposal: auto liability limit, cargo limit and deductible, physical damage values, general liability, workers compensation or occupational accident, and any excess layer. If you use owner-operators, ask how their non-trucking and equipment coverage is handled.
Request the cargo form and read the exclusions. Look for limits on unattended vehicles, refrigeration breakdown, certain commodities, and theft conditions. If you are a broker, ask whether the coverage is contingent cargo or a broader legal liability form, and whether broker contingent auto liability and E&O are available.
Check Great West's current AM Best rating yourself on the AM Best site rather than relying on any marketing page.
Confirm that the insurer will file the required federal and state proof of coverage, such as the BMC-91X, and how long filings take. Brokers should confirm whether a BMC-84 surety bond is available here or must be sourced elsewhere.
Ask how claims are assigned, whether you will have a dedicated adjuster, and what the after-accident response looks like. If you are a larger fleet, ask about large deductible and captive options and what collateral is required. Finally, ask what safety services come with the policy and whether participation affects pricing.
Company background
Great West traces its roots to 1936, when Joseph A. Morten started a business helping truckers obtain operating authority from states. His son, Joseph W. Morten, later joined, and the business moved into insurance. Great West Casualty Company was created in 1956.
The company joined the Old Republic Insurance Group in 1985 and remains an operating company of Old Republic International Corporation, which is publicly traded on the New York Stock Exchange under the symbol ORI. Old Republic itself was founded in 1923. Great West lists six corporate values: celebration, empowerment, integrity, opportunity, respect and service.
