VIN reports an discussion between Rav Chaim Kanievsky and a bochur who drove without a license and had an accident.
This is discussed by Rav Sternbuch in volume 1 #850. A similar conclusion that the driver is a rodef and can be reported to the police is found in Minchas Yitzchok, Tzitz Eliezar and Rav Ovadiya Yosef.
Rav Sternbuch quotes the Steipler as follows:
...(R’ Yaakov Kaniefsky was very angry with those who violated traffic laws whose purpose is to protect the lives of the members of society. I heard that someone once came to him because he was worried that he was about to receive a very severe punishment because he had violated the traffic laws. He wanted to receive a beracha that he would be free of the punishment. R’ Kaniefsky replied with a very sharp admonition and told him that in truth he deserved to be punished!) (This was even though R’ Kaniefsky was not necessarily in agreement with the secular laws in general). Therefore it would appear that if the person is considered a danger to society and since we can’t punish him ourselves, he should be reported to the police – with the permission of beis din or the rabbi of the community. This is in fact a mitzva since it is saving the community from harm and possible death.
