For one Chicago household, the surprise wasn't that their auto insurance cost increased after they added their teenager to the policy. It was the surprisingly low cost of one insurer's quote compared to others.
State Farm's quote was roughly 49% lower than the competing offers the family received, and that big discount prompted a different question: Was the cheap price actually a warning sign?
Here's what to know
The parents described their situation in a Reddit thread after adding their 16-year-old daughter to the family's USAA policy. With the premium jumping, the parent looked at quotes from Erie, Auto-Owners, Liberty Mutual, Amica, and State Farm.
According to the post, most of those quotes landed in a similar band — within about $500 of one another and close to what the household was already paying through USAA.
But State Farm sharply stood out, coming in about $2,500 less.
Faced with that gap, the parent asked whether the quote was suspiciously cheap. "Should I take this price as a red flag? (ie., if it seems too good to be true, it usually is). Is State Farm's quality of service considerably lower and worth paying $2,500 more to go with another company?" the original poster wrote.

The responses generally suggested the low quote was not automatically a problem, especially for a family insuring a young driver. One commenter wrote, "Make sure to carefully review the exact coverage they quoted you for!" Another added, "State Farm does have lower auto rates compared to other big name companies."
More background
Teen drivers are often among the most expensive people to insure because insurers view them as higher-risk behind the wheel. As a result, a family adding a 16-year-old can see a steep premium increase even with no accident history, making comparison shopping especially important.
Some commenters said the difference may simply reflect how State Farm prices policies for families with youthful drivers. One commenter who identified themselves as an agent with a competing insurer said, "They just have very good rates with youthful drivers." Another commenter shared criticism about one rival carrier: "Erie hates youthful drivers. They do not want that market and price accordingly."
Other replies highlighted how much insurers can differ in the way they evaluate risk. One commenter said USAA was 40% more expensive than State Farm in Pennsylvania, while another noted that certain non-collision claims may be treated more favorably by one carrier than by another.
What can be done?
Commenters' practical advice was to compare each quote line by line, including liability limits, deductibles, listed drivers, exclusions, and discounts. Several warned that an attractive price can be misleading if the teen driver is not included the way the family assumes.
One commenter advised, "Make sure your 16-year-old is actually listed on the policy." That commenter added, "Never listen to any agent who doesn't have you list or exclude every driver in the household."
Consumers may also benefit from checking more than the standard list of carriers. In the thread, one commenter recommended checking Costco's insurance option, administered by American Family, and the original poster replied, "The AmFam quote is really competitive."
As one commenter put it: "Not a red flag, State Farm does have lower auto rates compared to other big name companies."
