If a women goes into labour on Shabbos while living in Israel, is it better to order a taxi where the driver might be a Jew or ask ones husband to drive to the hospital
What is best is to take an ambulance, after that it is better that her husband should drive. This is because he knows that he is doing because of pikuach nefesh, and because he will be driving less. (Note: when getting to the hospital, he shouldn’t turn off the motor, but if it will cause him significant financial loss he can hint to a gentile to do it.)
