As far as I know, there is no pattern (with 100% surety) to when they ask for DL, however, validating the address seems to be one obvious purpose. Many previous posters have been seen discussing this when they live at one address, and use another address for filing GC (or they moved but did not update the DL). However, in many of these discussions, a DL was not actually asked during the interview time. My advice will be to carry at least whatever is asked for.
