Reply To: Rav Moshe Feinstein: Sitting next to women on buses

Rav Moshe has THREE seperate teshuvos strongly saying it is ASSUR to shake a woman’s hand.

And the above teshuva is VERY CONDITIONAL — i.e. only if there are no other available seats. So Rav Moshe is clearly saying (like the current gedolim) that Mehadrin buses with seperate seating is much much better.
