What it means
Car accidents can cause large costs, and a driver without money or insurance may be unable to pay for them. Financial responsibility laws deal with this problem by requiring drivers to prove they have a way of paying.
Almost every state in the United States has such a rule, although the details vary. In many states, the rule is a compulsory insurance law: you must hold a minimum amount of liability cover before you can register or drive a vehicle.
Other approaches require proof only after an accident or a serious traffic offence. In that case the driver may have to file a certificate with the state, often called an SR-22, which confirms that the insurer will notify the state if the policy lapses.
Minimum limits are usually written as three numbers, such as 25/50/25. These stand for the maximum paid per person for bodily injury, the maximum per accident for bodily injury and the maximum for property damage, each in thousands of dollars.
The actual numbers are set by each state and can be changed by law. For a business, the topic matters for any company that owns or hires vehicles.
Fleet managers must ensure that every vehicle meets the legal minimum, and most prudent businesses buy much higher limits, because the minimums are often too low to cover a serious accident. Employers can also be liable for accidents caused by staff on company business.
The nuance is that meeting the legal minimum is not the same as being adequately protected. A driver at fault in a serious accident can be sued for the amount that exceeds the policy limit, and personal or company assets may be at risk.
Finance teams should therefore look at the cost of higher limits or an umbrella policy as part of risk management.
In practice
Real-world examples.
Example
A young driver registers a car and must show proof of insurance meeting the state minimum. He buys a policy with 25/50/25 limits. The registry accepts the proof and issues the plates.
Example
A delivery company with 30 vans buys cover with limits of $1,000,000 per accident, far above the state minimum. The finance manager explains that the legal minimum would not cover a serious injury claim. The extra premium is treated as a necessary operating cost.
Example
A driver is convicted of a serious offence and the state requires an SR-22 certificate before reinstating the licence. His insurer files it and charges a small fee, and his premium also rises. If the policy lapses, the insurer must tell the state.
Formula
Calculation
Uninsured amount = Total damages - Insurance limit (for each category)
A state requires 25/50/25 limits, meaning $25,000 per person for injury, $50,000 per accident for injury and $25,000 for property damage. A driver causes an accident that injures one person with $40,000 of costs and damages another car for $10,000. The injury claim exceeds the per person limit, so the insurer pays $25,000 and the driver owes 40,000 - 25,000 = $15,000. The property claim of $10,000 is below the $25,000 limit, so it is covered, and the driver's total out-of-pocket exposure is $15,000.Case study
Seen in the real world.
Redstone Courier Services is an illustrative, fictional company with a small fleet of vans. A new operations manager checked the insurance policy and found that it met the minimum required by law, with limits of 25/50/25 on each vehicle.
She asked the broker to model a serious accident that injured several people and caused $400,000 of injury costs. Under the minimum cover, the insurer would pay no more than $50,000 for the injuries in one accident, leaving the company exposed to 400,000 - 50,000 = $350,000.
After comparing quotes, the company raised its limits and bought an umbrella policy for an additional premium of $6,000 a year. The illustrative lesson is that meeting the law is the starting point for protection, not the end.
Watch out
Common mistakes.
- Assuming the legal minimum is enough cover, when a serious accident can easily exceed it.
- Letting a policy lapse, which can lead to fines, licence suspension and a need to file extra proof of insurance.
- Forgetting that employers can be liable for accidents involving staff driving on company business.
