At-Fault Rear-End: Excess Exposure and the Duty to Settle

Attorney Answer

Nobody can honestly give you odds, and this page will not try. What can be described is what actually drives that outcome — and most of it sits with your insurer rather than with you. A demand for your policy limits, sent by a lawyer to your insurance company, is usually aimed at your insurer, and California law puts real pressure on an insurer to answer one properly.

Liability first, since your account settles it. Cal. Veh. Code § 21703 provides: "The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicle and the traffic upon, and the condition of, the roadway." Cal. Civ. Code § 1714(a) makes a person responsible for an injury occasioned to another by a want of ordinary care, except so far as the injured person brought the harm upon themselves. California is a pure comparative fault state: any share of the blame that belongs to the other driver reduces what he recovers in proportion, and never removes the claim entirely. The California Supreme Court reaffirmed and applied that system in Daly v. General Motors Corp., 20 Cal. 3d 725 (1978), under which a plaintiff who is partly to blame has the recovery cut by that share rather than taken away.

Now the part you asked about. How your insurer handles a demand inside your limits is governed by a duty it owes you. In Comunale v. Traders & General Ins. Co., 50 Cal. 2d 654 (1958), the California Supreme Court held that an insurer's unwarranted refusal to settle within the policy limits, where there is a great risk of a judgment above them, breaches the implied covenant of good faith and fair dealing and can leave the insurer answerable for the whole judgment rather than only its limits. Crisci v. Security Ins. Co., 66 Cal. 2d 425 (1967), states the same rule from the other direction: an insurer may not reject a settlement within limits to serve its own interest unless it is willing to absorb the excess loss that follows. That is why a limits demand carries weight. If your insurer turns down a reasonable one and a larger judgment follows, the exposure for the excess can land on the insurer.

None of that guarantees a settlement. The other side can sue instead, and Cal. Code Civ. Proc. § 335.1 gives two years from the injury to do it. What you should not do is negotiate with them yourself or give your own account of the crash to their lawyer or their insurer.

If a judgment ever did exceed your coverage, California exempts some property from collection. Cal. Code Civ. Proc. § 704.730 sets a homestead exemption at the greater of the countywide median sale price for a single-family home in the prior calendar year, capped at $600,000, or $300,000, and that amount adjusts annually for inflation. Cal. Code Civ. Proc. § 704.010 exempts $7,500 in vehicle equity. Those are backstops, not a plan.

What you can do

1. Send every letter, demand and message from the other side to your insurer the day it arrives, and keep a copy of what you sent and when.

2. Ask your insurer, in writing, to keep you informed of any settlement demand within your limits and of its response, and to tell you promptly if it decides not to settle.

3. Do not give an account of the crash, or discuss the medical claim, with the other side's lawyer or insurer. Refer them to your carrier.

4. Preserve what already exists and change nothing: the collision report, photographs, your declarations page, and all correspondence.

5. Ask a local attorney about retaining personal counsel now — your own lawyer, alongside the one your insurer would provide — because a demand for your limits is the point at which your interests and your insurer's can separate.

6. If you are contacted about a citation or any criminal matter arising from the crash, speak with a local criminal-defense attorney before you answer anything.

7. Most lawyers offer a brief initial call at no cost, and a few minutes on your specific facts is worth more than any general guidance, including this page.

⏱ Time limits apply. A claim against you for injury to a person runs under Cal. Code Civ. Proc. § 335.1, which allows two years, and a claim for damage to the other vehicle under Cal. Code Civ. Proc. § 338(c)(1), which allows three. When each period began depends on the facts, and this page cannot calculate a date for you. Have a local attorney review those dates, and your coverage, against your own file now.
