    Driving Under the Influence of Coffee

    Questions of kosher status sometimes mask larger dilemmas that, when uncovered, demonstrate the

    complexity of applying straightforward laws. Principles are easy. Life is messy.

    The rabbis of Kosharot, an Israeli kosher supervision agency associated with Mechon Ha-Torah Ve-Ha-

    Aretz, were asked a complex question that is unique to Israel: Is it religiously problematic to buy coffee at

    a gas station that remains open on Shabbos? Across the globe, Jews can safely assume that gas

    stations, tankers and convenience stores are operated by gentiles, who are not bound by Shabbos

    regulations. However, in Israel, Jews often perform the gas station work. If you buy gas or goods at a gas

    station, particularly Saturday night, are you benefiting from or encouraging Shabbos desecration?

    The rabbis of Kosharot broke down the question into its different parts and concluded that it is best to buy

    at a Shomer Shabbos gas station. However, if there is a great need and no better option, you are

    permitted to buy from a gas station that is open on Shabbos. One example they gave is a driver who is

    tired and needs a cup of coffee to stay awake. This need overrides any of the other concerns discussed

    (Emunas Itecha, no. 98 p. 35).

    In a letter to the editor (ibid., no. 100, p. 183), Uriel Banner takes issue with the “permission” to buy

    coffee. He argues that it is an obligation. You should not be strict in one area of halachah (possible

    benefit from or support of Shabbos violation) if it will led to a greater violation (endangering oneself and

    others). Driving while tired is a life-threatening danger. He quotes a responsum by Rav Shmuel Wosner

    (Shevet Ha-Levi 8:301) about some who fell asleep in the middle of a long drive from New York to

    Montreal and got in an accident. Rav Wosner ruled that the driver was negligent for driving without

    sufficient sleep beforehand.

    R. Mordechai Walnow of Kosharot responded with an even stronger stance (ibid., p. 185). Coffee will not

    help someone who is too tired to drive. Its effect is temporary and otherwise limited. If you feel so tired

    that you might fall asleep at the wheel, you must pull over to the side of the road and rest, and perhaps

    splash cold water on your face. If, after this, you still feel like you need coffee, then you may buy it from a

    gas station even if it is not Shomer Shabbos.

    All this raises the question of how tired is too tired to drive? Many of us are constantly on the move and

    always tired. It is easy to say “Don’t drive when you are too tired” but much harder to define the

    parameters. Especially when you have young children in the car, it is difficult to make the decision to pull

    over to the side of the road and rest your eyes. You usually do not know you are so tired that your eyes

    are closing until they are closing, at which point it might be too late. I don’t have an answer to the

    dilemma other than recommending resting in advance (often impractical), opening your window (weather

    permitting) and drinking coffee.

    One thing this issue makes clear is that even if a state is subjective, it is still real. We may not know the

    precise boundary, but it is clear that you can be too tired to drive. Some people argue that if a boundary

    cannot be defined, the state is meaningless. For example, if you can dispute the precise definition of

    heresy, show examples of rabbis who stepped over various lines, then nothing is heresy. Exhaustion is

    one of many examples that demonstrate that gray borders do not undermine the state. Some people

    really are too tired to drive.
