Your Premium Jumped After One Accident
You manage a household policy covering three vehicles. One driver rear-ended another car at a stoplight. The claim was filed, the damage was paid, and now your renewal notice shows a premium increase that affects all three vehicles on the policy. You expected the at-fault driver's portion to go up, but the entire policy was re-rated.
Delaware carriers apply at-fault accident surcharges at the policy level, not the vehicle level. When one driver on a multi-vehicle policy files an at-fault claim, the carrier re-rates the entire policy. Every vehicle's premium reflects the new risk profile, even if the other drivers had no claims. This structural reality catches multi-car households by surprise because the surcharge compounds across every vehicle you insure together.

$25,000 / $50,000 / $10,000
Delaware requires $25,000 bodily injury per person, $50,000 per accident, and $10,000 property damage. After an at-fault accident, carriers re-rate your policy based on the claim amount relative to these minimums and your coverage selections.

At-Fault Surcharges Apply Per Policy
Delaware law does not cap at-fault accident surcharges. Carriers set their own surcharge schedules, filed with the Delaware Department of Insurance. The surcharge applies to the policy, not to the individual driver or vehicle. When you insure multiple vehicles on one policy, the at-fault claim triggers a policy-level re-rating that affects every vehicle's premium.
The surcharge duration typically runs three to five years from the accident date, not the claim-close date. During that window, your entire household policy carries the higher rate. If you add a fourth vehicle mid-term, that vehicle is quoted at the post-accident rate. If you drop a vehicle, the remaining vehicles still carry the surcharge until the lookback period expires.
Carriers writing multi-vehicle policies in Delaware include State Farm, Geico, Progressive, Allstate, Farmers, and Liberty Mutual. Each carrier's surcharge schedule differs. A smaller surcharge on a lower base rate can produce a lower total premium than a larger surcharge on a higher base rate, so comparing carriers after an accident is the only way to know which structure costs less for your household.
The at-fault surcharge re-rates every vehicle on your policy. A single claim affects your entire household's premium for three to five years.
How the Surcharge Compounds Across Vehicles
When you insure one vehicle, the at-fault surcharge applies to that vehicle's premium. When you insure three vehicles on one policy, the surcharge applies to the policy's total premium. The carrier recalculates the base rate for each vehicle, then applies the surcharge to the combined total. The multi-car discount still applies, but it applies after the surcharge, not before.
A household with three vehicles might see the first vehicle's premium increase, the second vehicle's premium increase by a similar percentage, and the third vehicle's premium increase proportionally. The total policy premium reflects the surcharge compounded across all three vehicles. Dropping one vehicle does not remove the surcharge from the remaining two. The surcharge stays with the policy until the lookback period expires.

Separate Policies Do Not Avoid the Surcharge
Some households consider splitting their vehicles onto separate policies after an at-fault accident to isolate the surcharge. Delaware carriers typically require all household vehicles to be listed on one policy or explicitly excluded. If you move one vehicle to a separate policy with a different carrier, both carriers will ask whether other household members own vehicles and whether those vehicles are insured elsewhere.
Splitting policies usually costs more than keeping them together, even with the surcharge. The multi-car discount applies only when every vehicle sits on the same policy. Losing that discount often outweighs any surcharge isolation you gain by splitting. Carriers also apply household underwriting rules: if one household member has an at-fault claim, the other household members' policies may be re-rated at renewal even if the vehicles are on separate policies.
The only scenario where separate policies make sense is when one driver genuinely lives at a different address and garages their vehicle there full-time. A college student with a car at school, or an adult child who moved out, can maintain a separate policy without triggering household underwriting. But two spouses or two household members at the same address will not avoid the surcharge by splitting policies.
Delaware Uninsured Motorist Rate
17.6%
Nearly one in six Delaware drivers carries no insurance. After an at-fault accident, your uninsured motorist coverage protects your household if the next collision involves an uninsured driver. Dropping coverage to offset the surcharge leaves you exposed.

Compare Carriers Before Your Renewal
Delaware carriers apply different surcharge schedules to the same at-fault claim. One carrier might apply a flat percentage increase to your total premium. Another might apply a tiered surcharge based on claim severity. A third might apply a surcharge that decreases each year during the lookback period. You will not know which structure costs less until you compare quotes.
Request quotes from at least three carriers that write multi-vehicle policies in Delaware. Provide the accident date, the claim amount, and the number of vehicles you insure. Ask each carrier how long the surcharge lasts and whether it decreases over time. Compare the total policy premium, not the per-vehicle premium, because the surcharge affects the entire household.

Your at-fault accident affects every vehicle on your Delaware policy for the next three to five years. The surcharge applies at the policy level, not the vehicle level, so splitting your vehicles onto separate policies will not isolate the increase. The only way to reduce your premium after an at-fault claim is to compare carriers and find the surcharge schedule that costs your household the least.
