The Short Answer
A deductible is your share of a collision or comprehensive claim — a fixed dollar amount (usually $250, $500, or $1,000) subtracted from what your insurer pays each time you file. You choose it when you buy the policy: a higher deductible buys a lower premium, and a lower deductible means the insurer covers more of every claim. It never applies to Texas's required 30/60/25 liability coverage, which pays the other party with no deductible. That means liability-only drivers never make a deductible decision at all — it only matters once you add coverage for your own car.
What It Covers
What It Does Not Cover
Real-World Texas Scenarios
An overnight storm leaves $4,200 in dents and a cracked windshield. Hail is a comprehensive claim, so with a $500 comprehensive deductible your insurer pays $3,700 and you pay $500. With liability-only coverage, the entire $4,200 would come out of your pocket — the state-required policy never pays for your own car.
Your liability coverage pays for the other driver's bumper and any injuries with no deductible — that side always pays in full up to your limits. Your own crumpled hood is a collision claim: on a $2,600 repair with a $1,000 deductible, your insurer pays $1,600 and you cover the first $1,000.
If you carry uninsured motorist coverage, it can pay for your repairs, though TDI notes these claims are also subject to a deductible. If you skipped it but carry collision, you can claim through collision instead, pay your deductible, and your insurer may recover it from the at-fault driver and reimburse you.
With a $1,000 deductible, the most collision coverage could ever pay you is roughly $2,500 — before you count the extra monthly premium. This is why many DFW owners of older, paid-off cars choose liability-only and bank the difference, while anyone financing a car usually must carry full coverage.
Cost in Dallas–Fort Worth (2026)
| Situation | Monthly | Notes |
|---|---|---|
| Liability-only, qualifying DFW driver (30/60/25) | From $28/mo | No deductible applies — liability pays the other party from the first dollar. |
| Liability-only, typical DFW driver | ~$74/mo median | A-LA 2026 bound-quote data across DFW; still no deductible decision to make. |
| Full coverage with $250 deductibles | ~$170–$270/mo | Highest premium, smallest out-of-pocket per claim; illustrative DFW range — varies by vehicle, ZIP, age, and driving history. |
| Full coverage with $500 deductibles | ~$155–$245/mo | The most common middle ground for DFW drivers balancing premium against hail risk. |
| Full coverage with $1,000 deductibles | ~$140–$220/mo | Lowest full-coverage premium — only pick it if $1,000 on short notice wouldn't strain you. |
Ranges are illustrative A-LA 2026 bound-quote data across 15 DFW offices; actual rates vary by ZIP, vehicle, deductible, record, and credit-free underwriting through A-LA's 35+ carrier network.
