Let’s pretend your sister in Dallas, is driving her brothers car, who lives in Fort Worth. The car is insured on hthe parents Safeco auto policy that was bought in Grand Prairie. Your sister has a wreck in Weatherford, Texas. Your sister also had insurance with Allstate on her own car she had purchased in Arlington. Your sister is at fault and the other driver suffers personal injury and property damage. Both Allstate and Safeco refuse to settle the claim being asserted against you and your sister because they believe the other company should be paying the claim or paying the claim on a pro-rata basis.
This can be a very frustrating position for someone to find themselves involved and is referred to as an “other insurance” issue. The above is roughly what happened in the case, Safeco Lloyds Insurance Company v. Allstate Insurance Company. This case was tried and then appealed to the Court of Appeals of Texas, San Antonio.
The general rule in the past has been that auto insurance coverage goes with the vehicle. If the coverage on the vehicle is not sufficient to pay all the lose incurred then, the driver of the vehicle who has separate coverage has this separate coverage kick in as secondary coverage. However, the laws have changed and each insurance policy has to be looked at and compared with the other policy that may provide coverage to see what the result may be in any particular situation.
