Chapter 23 Quiz: Commercial Auto and Fleet Underwriting

Twenty questions to check your grasp of the business auto policy, fleet exposure, driver selection, radius and compliance, hired-and-non-owned auto, the nuclear-verdict problem, and telematics. Answers are in the collapsed key at the bottom — work the question before you open it. All figures are illustrative.

Multiple choice

1. Commercial auto has run unprofitably for the property-casualty industry through much of the last decade primarily because of:

  • A. A surge in the frequency of auto crashes
  • B. Rising severity — large bodily-injury verdicts and settlements — even when frequency is flat or falling
  • C. The cost of physical-damage (collision) claims
  • D. Excessive premiums driving away good risks

2. On the business auto policy, the coverage symbol that designates any auto — the broadest liability — is:

  • A. Symbol 7 (specifically described autos)
  • B. Symbol 2 (owned autos only)
  • C. Symbol 1 (any auto)
  • D. Symbol 9 (non-owned autos only)

3. Writing liability on symbol 7 ("specifically described autos") rather than symbol 1 most directly risks:

  • A. Overpaying for physical damage
  • B. A coverage gap for hired and non-owned autos
  • C. Triggering a claims-made trigger
  • D. Violating the FMCSA hours-of-service rules

4. The single most important principle in underwriting commercial auto, per the chapter, is:

  • A. Insure the trucks, not the drivers
  • B. Insure the drivers, not the trucks
  • C. Insure the cargo first
  • D. Price strictly off the manual rate

5. "Fleet rating" (as opposed to rating each vehicle individually) generally becomes available when:

  • A. The fleet is garaged in more than one state
  • B. The fleet crosses a size threshold, so its own loss experience becomes partially credible
  • C. The fleet carries hazardous materials
  • D. The umbrella attaches

6. Radius of operations is a primary rating variable because it proxies:

  • A. The resale value of the vehicles
  • B. A bundle of correlated severity drivers — time on the road, highway speed, and driver fatigue
  • C. The number of drivers
  • D. The cargo value

7. A recent DUI on a driver assigned to a heavy flatbed should, for most carriers and accounts, lead to:

  • A. A modest rate debit
  • B. A schedule credit if telematics is present
  • C. Removal of the driver from the policy as a condition of coverage
  • D. No action, since it is a personal matter

8. "Hired & non-owned auto" coverage responds when:

  • A. A scheduled company truck is damaged in a collision
  • B. An employee causes a crash while using a rented truck or their own personal car for company business
  • C. The cargo is stolen
  • D. A driver is injured on the job

9. The legal doctrine most often cited for why a plaintiff can reach the employer when an employee crashes a personal car on company business is:

  • A. Subrogation
  • B. Utmost good faith
  • C. Respondeat superior
  • D. Indemnity

10. A "nuclear verdict" is conventionally understood as:

  • A. A verdict involving a nuclear power facility
  • B. Any verdict above the policy limit
  • C. An exceptionally large jury award (tens of millions or more) far exceeding the economic damages
  • D. A verdict that voids the policy

11. The reason a clean fifteen-year loss history does not justify shading the auto rate is that:

  • A. Loss runs are usually falsified
  • B. The history records the frequency you can see, not the rare severity tail you can't
  • C. Fifteen years is too short a sample
  • D. Physical-damage claims dominate the history

12. The fundamental limitation of the MVR as a measure of driver risk is that it shows:

  • A. Only convictions — a biased subset of actual driving behavior
  • B. Too much detail to be useful
  • C. Behavior in real time
  • D. The driver's credit history

13. A growing number of carriers treat telematics/dashcams on heavier fleets as:

  • A. An automatic 50% discount
  • B. Irrelevant to underwriting
  • C. A requirement (a condition of coverage), much like a sprinkler certification on a property risk
  • D. A substitute for ordering MVRs

14. Before granting a schedule-rating credit for telematics, the question that actually matters is:

  • A. "Do you have telematics?"
  • B. "What brand of device is it?"
  • C. "What do you do with the data — do you coach and remove drivers based on it?"
  • D. "How much did the hardware cost?"

15. A dashcam's value in a severity-driven line, beyond changing driver behavior, is primarily that it:

  • A. Lowers the physical-damage premium automatically
  • B. Serves as evidence that can defend or defeat a disputed-liability claim
  • C. Replaces the need for liability limits
  • D. Satisfies the coinsurance clause

Short answer

16. Explain why "twelve units" tells you almost nothing about a fleet's exposure, and name the fleet characteristics that actually determine the risk.

17. The chapter says you underwrite "two things at once" when you evaluate a fleet's drivers. What are the two, and why is the second (the insured's process) often the more important?

18. Explain, using the frequency × severity framing from Chapter 6, why commercial auto's risk has "migrated into the tail," and what that does to the value of a model that predicts crash frequency well.

19. A broker argues the FMCSA public safety data is "just bureaucratic noise." Make the underwriting case for why you pull it anyway, and what it lets you do that the application alone cannot.

20. Why is the discipline to charge an adequate commercial-auto rate especially hard — and especially important — in a soft market? Tie your answer to the combined ratio (Chapter 3) and to the delayed arrival of severity losses.


Answer key (try the questions first) **1.** B — Frequency has been flat or falling; the line's losses are driven by rising *severity* (large bodily-injury verdicts and settlements), which is why it runs unprofitably even in low-frequency years. **2.** C — Symbol 1 (any auto) is the broadest liability designation, reaching owned, hired, non-owned, and future-acquired autos. **3.** B — Symbol 7 covers only the specifically described autos, silently excluding hired and non-owned vehicles; an employee's at-fault crash in a personal car then comes back uncovered. **4.** B — Insure the drivers, not the trucks. The vehicle is safe or dangerous depending entirely on who drives it and how. **5.** B — Fleet rating becomes available once the fleet is large enough for its own loss experience to be partially credible (Chapter 10), so the plan blends the fleet's experience with the class rate. **6.** B — Radius proxies a correlated bundle: time on the road, highway speed, fatigue, and distance from base. A single field standing in for several severity drivers. **7.** C — Removal of the driver as a condition of coverage. When one at-fault serious-injury claim can exceed the fleet's lifetime premium, there is no adequate rate for a recent DUI on a heavy unit. **8.** B — HNOA is liability for vehicles the insured uses but does not own: *hired* (rented/leased/borrowed) and *non-owned* (others' vehicles, especially employees' personal cars used for business). **9.** C — Respondeat superior: the doctrine that can make an employer liable for an employee's acts in the course of employment, regardless of who owns the vehicle. **10.** C — An exceptionally large jury award (conventionally tens of millions or more) far in excess of the economic damages, now clustering in commercial-auto/trucking liability. **11.** B — The clean history records the *frequency* you can observe, not the rare, enormous *severity* tail you cannot. A spotless fleet and a fleet that draws a nuclear verdict next year can be the same risk today. **12.** A — The MVR shows only convictions — a biased subset of behavior. A constant speeder never caught looks clean; one unlucky ticket looks worse than the driver is. Necessary, not sufficient. **13.** C — A requirement/condition of coverage on heavier fleets, analogous to requiring a sprinkler certification on a property risk (Chapter 19) — the control is that load-bearing. **14.** C — "What do you *do* with it?" A black box nobody reviews improves no risk; the credit belongs to a closed-loop program that coaches and removes drivers, not to the hardware. **15.** B — Evidence. Footage that shows the company truck was not at fault can convert a presumed-liable claim (big truck, injured plaintiff) into a defensible or defeated one — often paying for the whole camera program the first time. **16.** "Twelve units" is a headcount, not an exposure: a dozen sales sedans and a dozen heavy flatbeds hauling steel are entirely different risks. The exposure is set by vehicle type and weight, use, radius of operations, cargo, and who drives — read the *composition*, never the count. **17.** You underwrite the drivers *on the schedule today* (a snapshot) and the insured's *system for managing drivers over time* (the movie). The process matters more because the roster will turn over during the term; a disciplined hiring/MVR/disqualification process is what actually governs the loss future. **18.** Frequency losses are many, small, and predictable, so they average out under the law of large numbers (Chapter 1); severity inflation pushes the risk into the rare, enormous tail, which does *not* average out on a small fleet. A model that predicts frequency superbly is therefore still blind to the catastrophic verdict that breaks the account — the underwriter must supply severity discipline the model cannot. **19.** The FMCSA profile (SAFER/SMS, tied to the USDOT number) is a regulator-maintained, third-party read on the exact risk: crash history, roadside-inspection and out-of-service results, and safety percentiles (unsafe driving, hours-of-service, vehicle maintenance, driver fitness). It independently tests the story the application tells — a carrier that claims a tight operation but shows a high out-of-service rate is contradicting itself, and the public data is usually the more honest witness. **20.** In a soft market the premium is small relative to the whole account, brokers push, and clean histories are genuinely clean, so shading the auto rate is easy and looks costless — for two or three years. The severity losses arrive late; by the time the tail develops, the carrier is staring at under-reserved liability business and a combined ratio (Chapter 3) driven past 100% on rates set inadequately years earlier. No line punishes "we'll make it up on volume" harder.
