Tennessee liability rates follow a three-tier cost ladder for drivers with violations: a speeding ticket adds an average of $121 per year over clean-record rates, an at-fault accident adds $224 per year and a DUI adds $340 per year. Tennessee requires an SR-22 filing after certain violations, including DUI. Farm Bureau is the cheapest provider across all three violation categories, and it applies no surcharge at all for speeding tickets or at-fault accidents.

Farm Bureau charges $27 per month ($319 per year) after a speeding ticket — identical to its clean-record rate, meaning it applies no surcharge for this violation. The $121 per year average increase across all providers is the smallest of the three violation types on this page. Auto-Owners and Erie Insurance are the next cheapest at $40 and $41 per month.

Farm Bureau again charges $27 per month ($319 per year) after an at-fault accident, applying no surcharge for this violation either. The $224 per year average increase across providers is nearly double the speeding ticket surcharge. Most Tennessee providers apply this surcharge for three to five years following the accident date, so the total cost over that period ranges from $672 to $1,120 above clean-record rates.

Farm Bureau offers the cheapest liability car insurance in Tennessee after a DUI at $42 per month ($502 per year), the only violation tier where it applies any surcharge. State Farm is second at $44 per month ($524 per year). The $1,186 per year gap between Farm Bureau and Nationwide for this profile — and Tennessee's SR-22 filing requirement after a DUI conviction — make provider comparison especially important after this violation.

Poor credit adds $413 per year to Tennessee liability rates, more than the $340 per year DUI surcharge, making it the largest single rate factor on this page. The average rate with good credit is $48 per month ($581 per year) compared to $83 per month ($994 per year) with poor credit. GEICO is the cheapest option for drivers with poor credit at $57 per month ($686 per year), while State Farm — second cheapest overall with good credit — rises to $96 per month ($1,151 per year), a ranking shift that shows why drivers with credit challenges should compare rates across all providers rather than assume their current insurer offers the best price.
