A practical guide to using UM/UIM coverage when the other driver has no insurance—or not enough
UM vs. UIM in plain English
Idaho insurers must provide UM/UIM disclosures and typically offer these coverages alongside your policy, with limits that often match your bodily injury liability limits unless you choose otherwise. In many situations, you can reject UM/UIM in writing—but that decision can become painfully expensive after a serious crash.
Why this matters in Boise and the Treasure Valley
For construction managers, contractors, and business owners, the consequences of an uninsured-driver crash can be amplified: missed site time, project delays, and physical work restrictions can quickly turn into real financial pressure. UM/UIM coverage is designed to reduce that risk—but only if the claim is handled correctly.

2) Multi-vehicle impacts: Chain-reaction crashes can create disputes about who is “legally responsible” and how UM/UIM applies.
3) County-level crash trends: Idaho’s crash reporting includes county and city breakdowns showing how local crash patterns can shift year-to-year—useful context when thinking about risk and coverage choices in Ada County and the Boise area.
