How does a master service agreement affect my oilfield trucking insurance?
Commercial insurance broker
A master service agreement affects your oilfield trucking insurance by setting the indemnity terms, insurance requirements, and endorsements you've agreed to provide, and your policies need to be built to support those commitments. If the coverage doesn't match the contract, you may be personally on the hook for obligations your insurance won't pay.
Most MSAs include indemnity provisions, often reciprocal or knock-for-knock arrangements where each party takes responsibility for its own people and property regardless of fault. They usually require minimum limits for auto, general liability, workers' compensation, employer's liability, and umbrella coverage. They commonly require additional insured status, waivers of subrogation, and primary and noncontributory wording in favor of the operator and sometimes its other contractors.
State law adds another layer. Some states, including Texas and Louisiana, have oilfield anti-indemnity statutes that limit when certain indemnity provisions are enforceable, and some of those statutes interact with insurance requirements in specific ways. The result is that two MSAs with similar language can work very differently depending on where the work happens.
Practical steps help. Keep a log of every MSA you've signed and its insurance requirements. Have your broker review new agreements before you sign, and involve an attorney on indemnity terms. Make sure your certificates reflect what your policies actually provide.
