1. What does Commercial General Liability (CGL) coverage typically include?
  1. A Only worker injuries
  2. B Coverage A (Bodily Injury and Property Damage Liability), Coverage B (Personal and Advertising Injury Liability), and Coverage C (Medical Payments) — protecting businesses against third-party liability claims
  3. C Only product damage
  4. D Only contractual liability

Explanation

Commercial General Liability (CGL) is the foundation of most business liability insurance programs. Three coverage parts: (1) Coverage A — Bodily Injury and Property Damage Liability — pays for damages the insured is legally liable for from accidents on premises, operations, products, or completed operations; (2) Coverage B — Personal and Advertising Injury Liability — covers offenses like libel, slander, false arrest, copyright infringement in advertising, malicious prosecution; (3) Coverage C — Medical Payments — pays medical expenses for non-employees injured on the insured's premises or by the insured's operations, regardless of fault, with low limits (usually $5,000-$10,000) to avoid litigation. CGL excludes auto, professional services, workers compensation, intentional acts, contractual liability (with major exceptions), liquor liability (for liquor-selling businesses), and damage to the insured's own work or products.

2. What is the difference between an 'occurrence' and a 'claims-made' CGL policy?
  1. A They are identical
  2. B Occurrence triggers coverage based on when the bodily injury or property damage happened, regardless of when the claim is filed; claims-made triggers coverage based on when the claim is first made against the insured (subject to retroactive date and tail provisions)
  3. C Occurrence is illegal
  4. D Claims-made is cheaper

Explanation

These are two fundamentally different ways of triggering CGL coverage. Occurrence: coverage is triggered by when the bodily injury or property damage actually occurred. A 2024 policy covers a 2024 injury even if the claim is filed in 2028. Provides 'long tail' coverage automatically. Claims-Made: coverage is triggered by when the claim is first made against the insured, regardless of when the injury occurred. Includes a 'retroactive date' (earliest date covered) and requires that both the injury and the claim fall within policy terms. Requires 'tail coverage' (extended reporting period) to protect against claims made after policy termination for incidents during the policy period. Most CGL policies are occurrence-based, which is generally preferred. Professional liability (E&O, malpractice) is often claims-made because of the long delay between alleged malpractice and litigation. Switching between policy types creates coverage gaps if not managed carefully.

3. What does the CGL 'products-completed operations' coverage protect against?
  1. A Damage to the insured's own products
  2. B Liability for bodily injury or property damage caused by the insured's products after they are sold or by completed operations after the work is finished and the insured has left the site
  3. C Damage during transit
  4. D Manufacturing defects only

Explanation

Products-Completed Operations coverage under CGL Coverage A protects against liability claims arising after the insured's products are sold and out of their possession, or after the insured's work is completed. Two distinct exposures: (1) Products — manufactured or distributed items that cause injury or damage after sale (a defective ladder that collapses, contaminated food that makes someone sick); (2) Completed Operations — work performed by the insured that causes injury or damage after the work is complete and the insured has left the site (a contractor's faulty wiring that starts a fire months later). The 'aggregate limit' for products-completed operations is typically separate from the general aggregate, doubling the coverage available for these exposures. Critical for manufacturers, distributors, retailers, and contractors. Excluded from CGL: damage to the insured's own product or work; recall of defective products (requires separate product recall coverage).

4. What are the typical limits and aggregates in a CGL policy?
  1. A Only a single overall limit
  2. B Per-occurrence limit (max per claim), general aggregate (max for all claims in a policy period for premises/operations), products-completed operations aggregate (separate aggregate), personal/advertising injury limit, fire damage limit, medical payments limit
  3. C Unlimited coverage
  4. D Per-day limits

Explanation

A standard CGL policy has multiple limits structured to provide layered protection. Each Occurrence Limit: the maximum for any single occurrence (e.g., $1 million). General Aggregate Limit: the maximum total payable in a policy period for premises and operations claims (e.g., $2 million). Products-Completed Operations Aggregate: a separate aggregate for products and completed operations claims (e.g., $2 million). Personal and Advertising Injury Limit: per offense, often equal to the occurrence limit. Damage to Premises Rented to You: typically $50,000-$100,000 for fire damage to premises the insured rents. Medical Payments Limit: typically $5,000-$10,000 per person. Understanding aggregates is critical — once exhausted, no more coverage is available in that policy period. Businesses with claim activity may want higher limits or additional umbrella coverage. Limit selection should reflect the insured's exposure, not just minimum requirements.

5. What is 'completed operations' coverage in CGL?
  1. A Coverage for closing a business
  2. B Coverage for liability arising from the insured's work after the work is completed and the insured has left the work site — for example, a contractor's faulty wiring that causes a fire months later
  3. C Coverage for completed payments
  4. D Coverage for office tasks

Explanation

Completed Operations coverage protects against liability claims arising from the insured's work after the work is completed and the insured has left the work site. Critical for contractors, repair services, installers, and similar businesses. The 'completed operations hazard' is defined to include work that has been substantially completed at the work site, or work that has been put to its intended use, after the contractor leaves. Example: an electrician completes a wiring job; a year later, faulty wiring causes a fire — that is a completed operations claim. Without completed operations coverage, the electrician's CGL would not respond. Most CGL policies include completed operations automatically (subject to a separate aggregate limit), but some policies and endorsements exclude or limit it — particularly for construction defects. Completed operations coverage often must be maintained for years after the work is done to cover delayed manifestations of problems.

6. What is the difference between an 'occurrence' policy and a 'claims-made' policy in liability insurance?
  1. A They are the same
  2. B An occurrence policy covers claims for incidents that happened during the policy period regardless of when the claim is filed; a claims-made policy covers claims first made during the policy period (often requiring the incident to occur after a retroactive date)
  3. C Occurrence policies cost nothing
  4. D Claims-made policies never expire

Explanation

OCCURRENCE vs CLAIMS-MADE liability policies: OCCURRENCE POLICY: Covers claims arising from incidents that OCCURRED during the policy period — REGARDLESS of when the claim is filed (even years later, after the policy ended); the trigger is when the incident happened; CLAIMS-MADE POLICY: Covers claims that are FIRST MADE (reported) during the policy period; often requires the incident to have occurred after a RETROACTIVE DATE; the trigger is when the claim is made; TAIL COVERAGE (Extended Reporting Period): With claims-made policies, 'tail' coverage can be purchased to cover claims made AFTER the policy ends for incidents during the policy period; RELEVANCE: Common in professional liability, general liability, medical malpractice; the distinction matters for when coverage applies and for continuity when changing policies; occurrence policies provide longer 'reach' for old incidents; claims-made require attention to retroactive dates and tail coverage; understanding occurrence vs claims-made triggers is important casualty/liability exam content.

7. In a commercial general liability (CGL) policy, what does 'products-completed operations' coverage address?
  1. A The insured's office furniture
  2. B Liability for bodily injury or property damage caused by the insured's PRODUCTS after they leave the insured's possession, or by COMPLETED WORK after the insured finishes the job
  3. C Employee health benefits
  4. D The insured's vehicles

Explanation

PRODUCTS-COMPLETED OPERATIONS coverage (part of CGL): Covers liability for bodily injury or property damage arising from: PRODUCTS the insured made/sold AFTER they leave the insured's possession (e.g., a manufactured product later injures a user); and COMPLETED OPERATIONS — the insured's work after it's finished and turned over (e.g., a contractor's completed installation later fails and causes damage); CONTRAST: 'Premises and operations' covers injuries/damage occurring ON the insured's premises or during ongoing operations; products-completed operations covers harm AFTER products are sold or work is completed; AGGREGATE LIMIT: Often has a separate products-completed operations aggregate limit; IMPORTANT for: manufacturers, contractors, retailers — anyone whose products or completed work could later cause harm; CGL provides broad liability coverage for businesses; products-completed operations is a key component addressing post-sale/post-completion liability — important commercial casualty exam content.

8. What is 'vicarious liability'?
  1. A Liability for one's own direct actions only
  2. B Legal responsibility one party bears for the actions of another — for example, an employer being liable for the negligent acts of an employee committed within the scope of employment
  3. C A type of property coverage
  4. D Liability that cannot be insured

Explanation

VICARIOUS LIABILITY: Legal responsibility that one party bears for the wrongful actions of ANOTHER, based on their relationship. CLASSIC EXAMPLE: RESPONDEAT SUPERIOR — an EMPLOYER is liable for the negligent acts of an EMPLOYEE committed within the SCOPE OF EMPLOYMENT (e.g., a delivery driver who causes an accident while working — the employer is liable); OTHER EXAMPLES: A business liable for acts of its agents; parents (in some cases) for minor children; vehicle owners for permitted drivers (in some states); BASIS: The party held vicariously liable didn't commit the act directly but is responsible due to the relationship and control; INSURANCE: Liability policies often cover vicarious liability exposure (e.g., employers' liability for employees' acts); SCOPE OF EMPLOYMENT is key — the employee's act must be within their job duties; vicarious liability is an important liability concept on the casualty exam — understanding that businesses/employers can be liable for others' acts (especially employees within scope) shapes liability coverage needs.

9. What is the purpose of an 'umbrella' or 'excess liability' policy?
  1. A To replace all other insurance
  2. B To provide additional liability coverage ABOVE the limits of underlying policies (like auto and homeowners/CGL), and sometimes broader coverage — protecting against large claims that exceed primary limits
  3. C To cover property damage to the insured's home
  4. D To pay medical bills

Explanation

UMBRELLA / EXCESS LIABILITY POLICY: Provides ADDITIONAL liability coverage ABOVE the limits of UNDERLYING policies. HOW IT WORKS: Sits on top of primary policies (personal: auto and homeowners; commercial: CGL, auto, employers' liability); when a liability claim exceeds the underlying policy's limit, the umbrella pays the excess up to its (often high) limit (e.g., $1M-$5M+); EXCESS vs UMBRELLA: 'Excess' typically just adds limits over a specific policy; 'UMBRELLA' adds limits over multiple policies AND may provide BROADER coverage (covering some claims the underlying policies exclude, subject to a self-insured retention for those); REQUIRES underlying coverage at specified minimum limits; PROTECTS against catastrophic claims/judgments that exceed primary limits (protecting the insured's assets); RELATIVELY INEXPENSIVE for the high limits provided; umbrella/excess liability is important casualty coverage — it protects against large liability claims exceeding primary limits and is commonly recommended for asset protection; a key exam concept.

10. What is 'negligence' and what are its basic elements in a liability claim?
  1. A An intentional crime
  2. B Failure to exercise reasonable care, resulting in harm — its elements are duty, breach of duty, causation, and damages; all four must be present for a negligence claim
  3. C A type of insurance policy
  4. D A government regulation

Explanation

NEGLIGENCE: The failure to exercise the REASONABLE CARE that a prudent person would under similar circumstances, resulting in harm to another. FOUR ELEMENTS (all required): (1) DUTY — the defendant owed a legal duty of care to the plaintiff; (2) BREACH — the defendant breached that duty (failed to act with reasonable care); (3) CAUSATION — the breach actually and proximately CAUSED the harm; (4) DAMAGES — the plaintiff suffered actual harm/loss; ALL FOUR must be proven for a successful negligence claim; DEFENSES: comparative/contributory negligence (the plaintiff's own fault reduces or bars recovery); assumption of risk; COMPARATIVE NEGLIGENCE: damages reduced by the plaintiff's percentage of fault; LIABILITY INSURANCE: Responds to negligence claims (defense and damages); negligence is the basis of most liability claims — understanding the four elements (duty, breach, causation, damages) is fundamental casualty/liability exam content, as liability coverage exists primarily to respond to negligence claims against the insured.

11. What does Commercial General Liability (CGL) insurance protect a business against?
  1. A Damage to the business's own building only
  2. B Third-party claims for bodily injury, property damage, and personal/advertising injury arising from the business's operations, premises, or products
  3. C Employee injuries on the job
  4. D The business's lost income

Explanation

Commercial General Liability (CGL) insurance protects a business against third-party claims for bodily injury and property damage arising from its premises, operations, products, and completed work, as well as 'personal and advertising injury' (such as libel, slander, or certain advertising-related offenses). It pays damages the business is legally obligated to pay and the cost of defense, up to policy limits. CGL does not cover the business's own property (commercial property insurance), employee injuries (workers compensation), or professional errors (professional liability). Understanding the broad third-party liability protection CGL provides is core general-liability content on the casualty exam.

12. What is the difference between 'comparative negligence' and 'contributory negligence' systems?
  1. A They produce the same result
  2. B Under comparative negligence, a damaged party's recovery is reduced in proportion to their share of fault; under strict contributory negligence, a party even slightly at fault may be barred from recovering at all
  3. C Both bar all recovery
  4. D Both ignore fault entirely

Explanation

These are two legal approaches to handling situations where the injured party shares some fault. Under comparative negligence (used in most states, in pure or modified forms), the injured party can still recover damages, but the award is reduced in proportion to their own percentage of fault. Under the stricter contributory negligence rule (used in only a few states), a party who is even slightly at fault for their own injury may be completely barred from recovering. Which system applies affects liability claim outcomes and varies by state. Understanding the difference between comparative and contributory negligence is important liability-concepts content for adjusters and producers.
