Since both comprehensive and collision cover you regardless of fault, rental reimbursement is the same.
When you inform your insurance of the accident, you’ll be able to get more information about a rental car. Depending on your carrier and policy, there may be a specific rental car company they work with.
If so, the rental car company may bill your insurance directly. If there isn’t a specific company, you may be required to pay for your rental car and get reimbursed by your insurance later based on your policy limits.”
