The Halakhic Obligation to Obey Traffic Laws

Is there a Halakhic obligation to obey traffic laws?

Certainly, one must obey all traffic laws, as it is a matter of potential danger to life, which overrides the entire Torah. Especially when others see him and learn from his actions, such as children, etc., and he can never know if someone who learned from him lost their life.

And even if nothing ever happened to him, and no one learned from his actions, he often requires a miracle to be saved, and it is explained in the Gemara that one who experiences a miracle has their merits reduced.

The Chovot HaLevavot writes in Shaar HaBitachon, Chapter 4

Similarly, it is not appropriate for a person to put themselves in danger, relying on the decree of the Creator, and to drink deadly poisons, or to risk themselves by fighting with a lion and wild animals without necessity, or to throw themselves into the sea, or into fire, and similar things, in which a person is not secure and risks their life. And the Scripture has already warned us about this by saying (Deuteronomy 6:16): "Do not test the Lord your God" etc. For he will not escape one of two things: either he will die, and he will be the one who kills himself, and he will be accountable for this as if he killed another person, even though his death occurred by the decree and permission of God. And we have already been warned not to kill any person in any way, by saying (Exodus 20:13): "You shall not murder." And the closer the killed is to the killer, the greater the punishment. Or, he will be saved by the help of the Creator, blessed be He, and lose his merits, and lose his reward, as our sages, of blessed memory, have said on this matter (Gemara Shabbat 32a): "Never stand in a place of danger and say that a miracle will be done for you, for perhaps a miracle will not be done for you. And if a miracle is done for you, it will be deducted from your merits" etc.
