This doesn't apply directly to your question, but your response brings up a difference that it isn't clear if you understand. Depending on the age of your children, it could be a problem. However, your wife is definitely able to drive a vehicle with a handgun in it as that would be covered under the Motorist Protection Act. A police officer stopping her and suspecting or finding a concealed firearm on or about her while she's in the car would not be a legal problem in and of itself unless your wife is statutorily forbidden from having a firearm (eg a felon).
