A hazard, in insurance terminology, is best described as:

Why B is correct

A hazard is a condition, circumstance, or factor that increases the probability or severity of a loss. Hazards are classified as physical, moral, or morale: a physical hazard is a tangible condition such as defective wiring, a moral hazard is dishonesty such as deliberately causing a loss, and a morale hazard is carelessness that arises because insurance exists. Underwriters evaluate hazards carefully because they directly affect the likelihood of a claim and therefore the premium that must be charged for the risk being considered.

Why the other options are wrong

• A) The event that actually causes a loss is a peril, not a hazard. Hazards only make a loss more probable; they do not themselves produce the loss. The peril is the event such as fire or theft; the hazard is the underlying condition that makes that event more probable.
• C) Uncertainty about whether a loss will happen is the definition of risk. Risk, peril, and hazard are three distinct concepts that applicants are expected to separate. Risk is the uncertainty of loss, hazard is the condition that increases it, and keeping the two separate is tested frequently.
• D) Depreciation over time is a valuation concept used to measure current worth. It is not a condition that increases the probability that a loss will occur. Wear and tear is a valuation adjustment for claims purposes, not a condition that increases the chance of a loss.

Memory hook

Hazard = the amplifier. It does not cause the loss; it makes the loss more likely.
