An orthodox Jew does one of two things:
- Takes another route to work that doesn't have a stop sign so that he doesn't run the risk of disobeying the Law.
- Stops at the sign, says Blessed art thou, O Lord our God, king of the universe, who hast given us thy commandment to stop, waits 3 seconds according to his watch, and then proceeds.
Incidentally, the Talmud has the following comments on this sign:
- Rabbi Meir says: He who does not stop shall not live long.
- Rabbi Hillel says: Cursed is he who does not count to three before proceeding.
- Rabbi Simon ben Yudah says: Why three? Because the Holy One, blessed be He, gave us the Law, the Prophets, and the Writings.
- Rabbi ben Isaac says: Because of the three patriarchs.
- Rabbi Yehuda says: Why bless the Lord at a stop sign? Because it says, Be still and know that I am God.
