How to think about auto insurance in Texas: what to buy and why

Updated May 21, 2026 — PolicyChat refreshes this page when new state DOI filings post.

For most Texas drivers, $300K/$300K liability is the right starting point. The math: most carriers price the jump from $100K/$300K to $300K/$300K at $8-18 a month, and the protection difference is real. A serious bodily-injury claim crosses $100K fast.

How to think about this

Texas is a file-and-use state with one of the most carrier-competitive auto markets in the country. The Texas Department of Insurance doesn’t pre-approve rate changes — carriers file and the rates are effective immediately unless TDI later orders a hearing.

The threshold to think harder is $500K in assets. Past that point, $300K/$300K plus a $1M umbrella is the standard package; the umbrella runs $150-300 a year and requires you to first carry $250K/$500K underlying. Below $500K in assets, $300K/$300K alone is plenty.

Texas-specific things to know

• File-and-use means rate changes are effective on filing, not after regulator approval.
• Hailstorm losses on the Caprock + I-35 corridor drive home rates; Houston/Galveston wind exposure drives coastal rates.
• Texas requires only $30K/$60K/$25K auto liability — well below the national norm of $50K/$100K.

When the recommendation changes

• Below $50K in assets: minimum required limits are fine.

• $500K-$2M in assets: $300K/$300K + $1M umbrella.

• Above $2M in assets: talk to a high-net-worth broker about $2M-$5M umbrella.
