CISR Commercial Casualty II common mistakes
CISR Commercial Casualty II · Understand the traps and how to avoid them.
Treating Part One (Workers' Compensation) and Part Two (Employers' Liability) of the WC policy as interchangeable, so the candidate applies the exclusive-remedy shield to Part Two claims or applies Part Two limits to statutory benefit payments.
Both parts sit on the same policy and share a declarations page, so candidates read one aggregate limit and assume one coverage. The distinction between statutory no-fault benefits and tort-based employer liability is easy to blur under exam time pressure.
What to do instead
Build a two-column comparison before answering: Part One pays benefits required by state statute regardless of fault, has no dollar limit in most states (the limit shown is for states with monopolistic funds or specific situations), and is the source of the exclusive-remedy bar. Part Two pays damages the employer is legally obligated to pay because of bodily injury to an employee, excludes liability assumed under contract and punitive damages in many forms, and is the part subject to per-occurrence limits. Then ask which part the fact pattern is actually triggering.
Answering questions about the three WC benefit categories (medical, indemnity, rehabilitation/death) using the wrong eligibility trigger, for example assuming indemnity benefits begin on the first day of disability or that medical benefits are subject to a waiting period.
Candidates memorize dollar amounts and percentages but not the mechanics of waiting periods, retroactive payment rules, and the difference between temporary partial, temporary total, permanent partial, and permanent total disability. Exam items often hinge on a date or a disability classification rather than a number.
What to do instead
Study the benefit mechanics state-by-state in the abstract: a waiting period (commonly a set number of days) before indemnity begins, with retroactive payment if disability extends beyond a longer threshold; medical treatment generally not subject to the waiting period; indemnity computed as a percentage of the state average weekly wage subject to a maximum and minimum. When a question gives a disability onset date, first classify the disability type, then apply the waiting period, then apply the wage-replacement percentage and cap.
Missing the employer's liability exclusions that appear in the standard policy, particularly the exclusion for liability assumed under contract, the exclusion for punitive damages, and the exclusion for injury to employees covered under a federal compensation law, and then selecting a coverage answer that ignores them.
These exclusions are buried in the Employers' Liability section rather than the WC section, and candidates skim the coverage grant without reading the exclusions list. The contract-assumption exclusion is especially easy to overlook because insured contracts are handled differently in other liability lines.
What to do instead
Memorize the Employers' Liability exclusion set as a short list and rehearse why each exists: contractual liability (the employer should not convert a voluntary indemnity agreement into insurance), punitive damages (uninsurable in many jurisdictions), federal compensation laws (FELA, Longshore, etc. are covered elsewhere or excluded), and injury to non-employees. When a fact pattern involves a hold-harmless agreement in a construction contract, immediately flag that Part Two will not respond.
Confusing the WC policy's other-states coverage with a true multistate endorsement, and answering as if the policy automatically provides full statutory coverage in every state at the same limits.
The other-states provision is a limited mechanism triggered by specific conditions (the employee is temporarily in another state, the employment is not principally localized in any one state, or the employee is a resident of the other state), and candidates treat it as blanket nationwide coverage.
What to do instead
Learn the three triggering conditions for other-states coverage and the fact that it responds as if the policy were issued in that state, subject to the policy's other-states limit and any state-specific endorsements. For questions about a multistate employer with permanent operations in several states, the correct answer usually involves state-specific endorsements or separate policies, not the other-states provision alone.
Applying the business auto policy's liability coverage to vehicles and exposures it does not reach, such as mobile equipment, autos used in a ridesharing arrangement, or autos the insured does not own but operates under a long-term lease treated as ownership.
Candidates learn the owned/hired/non-owned symbols as labels but do not connect them to the definitions of 'auto,' 'mobile equipment,' and 'who is an insured,' so they default to 'the policy covers it' whenever a vehicle is involved.
What to do instead
Anchor every business auto question on two definitions first: what counts as an 'auto' (including trailers and mobile equipment only when it meets the specific roadway conditions) and who qualifies as an insured for the symbol in play. Then check the symbol: a symbol 1 answer covers only owned autos, symbol 8 only hired autos, symbol 9 only non-owned autos. If the fact pattern involves a long-term lease, remember that a lease of a certain duration is treated as ownership for coverage purposes.
Treating the business auto policy's covered auto designations as if any designation grants the same scope of liability coverage, and choosing answers that ignore the difference between symbol 1 and the broader symbols.
The declarations page lists symbols as numbers, and candidates who have not drilled the symbol table assume the numbers are interchangeable or that a higher number always means broader coverage. In fact each symbol describes a distinct category and the exam tests whether the candidate can map a vehicle to the right category.
What to do instead
Memorize the symbol table as a grid: 1 = any auto, 2 = owned autos only, 3 = owned private passenger autos only, 4 = owned autos other than private passenger, 5 = owned autos subject to no-fault, 6 = owned autos subject to a compulsory uninsured motorists law, 7 = specifically described autos, 8 = hired autos only, 9 = non-owned autos only. Practice by reading a fact pattern and naming the symbol before looking at the answer choices.
Overlooking the business auto policy's exclusions that most often appear in exam items, especially the exclusion for autos used in the business of an insured other than the named insured, the racing exclusion, and the exclusion for vehicles while used to carry persons or property for a fee.
These exclusions are stated in dense policy language and candidates rely on general impressions of what auto insurance 'should' cover rather than the actual exclusion text. The for-a-fee exclusion is particularly tricky because it has exceptions.
What to do instead
Build a one-page exclusion list with the exception attached to each exclusion, and practice stating the exception aloud. For the for-a-fee exclusion, note the carve-outs (for example, a share-the-expense carpool or a vehicle used in a permitted public livery operation endorsed onto the policy). For the 'business of an insured other than the named insured' exclusion, identify whose business the vehicle is being used in before deciding coverage.
Assuming an excess or umbrella policy drops down to fill a gap in the underlying coverage or responds before the underlying limit is exhausted, and answering as if the umbrella is primary when the underlying policy denies a claim.
The word 'umbrella' suggests broad protection, and candidates conflate breadth of coverage with priority of payment. Excess and umbrella policies are written over underlying policies and generally require the underlying insurer to pay or the insured to exhaust the self-insured retention before the umbrella responds.
What to do instead
Separate the two concepts explicitly: an excess policy follows form and pays only after the underlying limit is exhausted; an umbrella policy may broaden coverage but still sits above a required underlying limit or self-insured retention. For any drop-down question, check whether the umbrella has a specific drop-down provision and whether the claim falls within the umbrella's own coverage grant. If the underlying policy denies coverage, the umbrella typically does not respond unless a drop-down provision says otherwise.
Ignoring the self-insured retention (SIR) and its interaction with the underlying limit when calculating how much an umbrella policy pays on a loss.
Candidates focus on the umbrella limit and the underlying limit but forget that the SIR is the insured's own money and must be satisfied before the umbrella attaches, and they also forget that defense costs may erode the SIR or the limit depending on the form.
What to do instead
Work a numeric example every time: loss amount, minus underlying limit paid by the primary, minus any SIR the insured must absorb, equals the amount the umbrella pays, capped at the umbrella limit. Then check whether the umbrella is written on a defense-within-limits or defense-outside-limits basis, because that changes whether defense costs reduce the available limit. Write the formula down before reading the answer choices.
Assuming the umbrella follows the underlying policy's terms exactly, including exclusions and conditions, and missing the situations where the umbrella is broader or narrower than the underlying.
Umbrella policies are often described as following form, and candidates stop there. In reality an umbrella can broaden coverage (for example, by covering personal injury or advertising injury not covered by the underlying) and can also impose its own exclusions and conditions that differ from the primary.
What to do instead
For every umbrella question, ask two questions in order: does the umbrella's own insuring agreement cover this loss, and does the umbrella's own exclusion list remove it? Only then consider whether the underlying policy would have covered it. Memorize the typical umbrella broadening areas (personal and advertising injury, some foreign exposures, some incidental exposures) and the typical umbrella-specific exclusions, and treat 'follows form' as a starting point rather than the whole answer.
