Q. What is the halacha regarding one who drives in a manner in which disregards traffic laws such as speed limits and stop signs, but he makes sure to be safe and respectful to other drivers?
A. Horav Shlomo Miller's Shlit'a opinion is that disregarding traffic laws may be prohibited by the Halacha of Dina Demalchusa or our obligation to observe and obey the laws of the land, besides their may be a strong possibility of creating a Chilul Hashem by the ones observing his traffic violations.
We may add, that even if this individual thinks he is making sure to be safe, the reality of the unexpected and sudden conditions and constant changes and circumstances of traffic in a road, may easily prove him wrong. Therefore he is endangering the life, limb and property of others.
The Rov maintains that if one is truly careful, the last point may not necessarily apply.
