Underinsured motorist
Underinsured motorist coverage pays the insured when the at-fault driver does carry liability insurance but does not carry enough of it to cover the loss.
It sits in the same subchapter as uninsured motorist coverage and is offered under the same rule in § 1952.101 — on the policy unless a named insured rejected it in writing. In Texas the two are usually sold together as UM/UIM.
It matters exactly where 30/60/25 stops. A driver carrying the state minimum can cause an injury that costs several times the per-person limit, and this is the coverage that answers for the remainder.
How much to buy is a household question rather than a definitional one, and it is on the auto insurance page.

Where this is handled
Knowing what a coverage is called is not the same as knowing what is on your policy. One independent agency can read your declarations page with you and compare the markets that will write your record.
