Final answer:
The fine for a motorist if a pedestrian suffers serious bodily injury varies by jurisdiction; the insurance premium example shows how insurance funds cover accident costs but does not detail fines for injuries.
Step-by-step explanation:
The specific fine a motorist would receive if a pedestrian suffers serious bodily injury as a result of the motorist's violation can vary significantly depending on the jurisdiction and exact circumstances of the violation.
However, the example provided shows an illustration of how automobile insurance premiums are used to collectively cover the costs of accidents within a group of drivers.
If the group of 100 drivers each pays an annual premium of $1,860, the insurance company collects $186,000 in total, which is the necessary amount to cover the damages sustained in accidents by the members of that group over that period.
This serves to explain how insurance premiums work but does not provide specific information on fines for causing bodily harm to pedestrians through traffic violations. Actual fines would be set according to local traffic laws and would likely involve additional legal consequences beyond a financial penalty.
