Car insurance in Brookside, DE, costs about $268 a month ($3,217 a year) for full coverage in ZIP code 19713, at the heart of the community, for our benchmark driver. Liability-only coverage at 15/30/10 limits averages $1,544 a year ($129 a month), and 50/100/50 liability with comprehensive and collision averages $3,211 ($268 a month).
Allstate is far more expensive than the other insurers here: its full-coverage average of about $482 a month is 2.2 times the average of the other four. We keep it in our averages because it’s a rate the insurer filed with state regulators; without Allstate, the Brookside average would be about $215 a month.
Progressive has the lowest full-coverage average among the insurers in our Brookside rate data that are among insurers anyone can buy from. USAA averages even less, at $178 a month, but it sells only to military members, veterans and their families. The recent statewide Delaware rate studies we reviewed disagree on which insurer is cheapest for full coverage: of the eight, two put GEICO first, two put Travelers first and four other insurers lead one each, apart from USAA, which sells only to military families. For liability-only coverage at 15/30/10 limits, GEICO has the lowest average among these four insurers, at about $86 a month, followed by State Farm at $106. USAA comes in even lower, at about $66 a month, but it sells only to military families.

Raising liability limits from 50/100/50 to 100/300/100 barely changes the average in our Brookside data: with the same $500 deductibles, full coverage averages $3,217 a year and 50/100/50 averages $3,211. The full-coverage package doubles the per-person injury limit, triples the per-crash limit and doubles the property damage limit, and it raises uninsured and underinsured motorist coverage to 100/300. Allstate and Progressive charge less for 100/300/100 than for 50/100/50 for our benchmark driver.
Not for our benchmark driver. Comparing the four insurers that are in both sets of rates, in the same Brookside ZIP code, their full-coverage average fell from $3,561 a year nine months earlier to $3,486 in rates as of Aug. 31, 2026, a 2.1% drop. State Farm cut its Brookside average 7.5% and Allstate 1.7%, while Progressive raised its average 1.2%; GEICO’s average was unchanged. USAA is new in our rates over the past nine months, so it’s left out, which is why these averages differ from the Brookside average above. Liability-only coverage at 15/30/10 limits fell 2.2%, led by Allstate, which cut its liability-only average 4.1%.
