Can two insurance companies insure the same car?

A vehicle may not be covered for the same coverage by more than one company.

However, it may be the case that liability coverage is with one insurer and physical damage coverage is with another. This can happen in the instance, for example, of a financed vehicle, where the lender obtains "forced-placed" physical damage coverage on the car to protect its interest in the collateral. The lender may do this if the owner/borrower does not produce proof that he/she has obtained physical damage coverage, despite having obtained liability or other required coverages.
