The baseline: permissive use
Lend your car, and California ties you to what the borrower does with it — that's statutory owner liability. The mercy is the cap: absent your own negligence, exposure is limited to the statutory amounts, and your auto policy's omnibus clause generally covers permissive drivers as primary. Translation: in the ordinary lent-car crash, your insurance handles it and your personal assets stay out of it.
Where the cap vanishes
Negligent entrustment — handing keys to someone you knew or reasonably should have known was drunk, unlicensed, or unfit — is YOUR negligence, uncapped and personal. Hypothetically: handing keys to a visibly swaying friend outside a pier-district bar could make their whole crash yours. The moment of the handoff is the whole case: what you knew, what you saw, what a reasonable person would have.
What to do right now
- Notify your insurer immediately — late notice creates coverage problems you don't need.
- Say nothing characterizing the lending — “I had no idea they'd been drinking” is a fact for counsel to frame, not a phone quote.
- Check your policy for exclusions — excluded drivers and prohibited-use clauses change everything.
- Get advice before any statement — entrustment turns on words about a two-second handoff.
And if the drunk borrower hurt YOU or yours
Flip side: injured as a passenger in your own lent car, or your family member hurt — claims exist against the driver, and your own coverage layers apply. The full victim playbook is the DUI-victim guide; whether pursuing the driver personally pays is its own honest math. Either seat you're in, the free consult sorts your exposure from your claim in one call.
