A rental from your OWN insurer is a different question from a rental against the other driver’s (third-party) insurer — and only some states turn the second one into an enforceable rule.
Where no rule is confirmed, insurers commonly pay anyway as a matter of practice. That is not the same as a legal guarantee.
Two different questions, two different coverages
A rental through your OWN policy depends on whether you bought optional rental reimbursement coverage — it is not automatic. A rental charged to the AT-FAULT driver’s insurer is a third-party loss-of-use claim, and whether that is an enforceable rule (rather than common practice) depends on the state.
States with a confirmed third-party rule
- Connecticut — if the other driver is clearly at fault, their insurer must pay reasonable loss-of-use compensation for your damaged car — even if you never actually rent a replacement vehicle (Conn. Agencies Regs. §38a-334-1 et seq.).
- New Jersey — comparable rental or substitute transportation must be paid until your car is repaired (partial loss) or the claim is settled (total loss) (N.J.A.C. 11:2-17.10(a)(8)).
- Illinois — the at-fault driver’s insurer reimburses your rental in proportion to their share of fault, generally for the normal repair period or until it offers to settle your vehicle damage — and it is not automatic before liability is accepted (Illinois DOI).
- Georgia — once the at-fault driver’s insurer accepts liability, it must pay your reasonable losses, including loss of use, towing and storage — subject to mitigation and your actual loss (O.C.G.A. §33-7-11.1).
- South Carolina — the at-fault insurer must reimburse reasonable and necessary loss of use; on a total loss, many insurers pay through a settlement offer as a matter of common practice, not a universal guarantee (SC DOI).
- Washington — if you have rental coverage under your OWN policy, your insurer cannot cut it off less than 7 calendar days after sending a total-loss payment, or before that coverage is exhausted. This is a first-party coverage-cutoff rule, not a third-party entitlement (WAC 284-30-391).
Guidance, not a codified rule
Oregon’s regulator advises that the at-fault driver’s insurer should pay for loss of use while your claim is reasonably being investigated — but this is regulator guidance, not a numbered legal mandate (Oregon DFR).
Where no mandate was found
North Carolina — no statute or administrative-code provision was found requiring a rental car during a claim. It is common industry practice, but not a legal mandate the way towing and storage protections are (N.C. Gen. Stat. §58-63-15).
Massachusetts, Arizona and Nevada confirm the same basic shape: a rental through your own insurer depends on optional coverage you bought, and ordinary coverage may not reach every cost a rental company can charge. None of these three confirms a numbered third-party rental deadline.
The legal entitlement — not just common practice — depends on the state. Jump straight to the relevant section.
