סימן קלה סעיף יח

הוֹלְכֵי דְרָכִים בַּיוֹם, פְּטוּרִין מִן הַסֻּכָּה בַּיוֹם, כֵּיוָן שֶׁאֵין לָהֶם שָׁהוּת לִטְרֹחַ אַחַר סֻכָּה, כֵּיוָן שֶׁצְּרִיכִין לֵילֵךְ תֵּכֶף לְדַרְכָּן. אֲבָל אִם יְכוֹלִים לֵישֵׁב בַּסֻּכָּה בְּלִי טֹרַח, חַיָבִים לֵישֵׁב בַּסֻּכָה. וּבַלַיְלָה, כְּשֶׁהֵם בַּמָּלוֹן שֶׁהֵם רוֹצִים לָלוּן שָׁם, צְרִיכִים לְהַטְרִיחַ אֶת עַצְמָם לֵישֵׁב בַּסֻּכָּה. וַאֲפִלּוּ אִם הֵם בְּמָקוֹם שֶׁאֵין שָׁם סֻכָּה, אִם יְכוֹלִים לַעֲשׂוֹת סֻכָּה בִּמְעַט מָמוֹן, חַיָבִים לְהִשְׁתַּדֵּל שֶׁתְּהֵא לָהֶם סֻכָּה לִישֹׁן בְּתוֹכָהּ. וְאִם הוֹלְכִים גַם בַּלַּיְלָה, דִּינָם כְּמוֹ בַיוֹם. וְהַהוֹלְכִים בַּכְּפָרִים לִגְבּוֹת חוֹבוֹת בְּחֹל המּוֹעֵד, אִם אֵינָם יְכוֹלִין לַעֲשׂוֹת לָהֶם סֻכָּה, יַחְמִירוּ עַל עַצְמָם לַחֲזוֹר לְבָתֵּיהֶם בְּכָל לַיְלָה לְקַיֵם מִצְוַת סֻכָּה.

People traveling in the daytime¹⁸According to Mishnah Berurah, you need not curtail your travel even if you know that you will not find a sukkah enroute. (Ibid 640:42) are exempt from eating in the sukkah during the day,¹⁹You need not delay eating until you are able to find a sukkah. Needless to say, however, if there is a sukkah nearby, that you can use without too much bother, you are not exempt, and you must eat in the sukkah. (Ibid 640:42) because they have no time to look for a sukkah, since they must move along.²⁰This rule applies only to those traveling for business. However those who travel for pleasure are forbidden to travel to places where they will have no sukkah. (Igros Moshe, Orach Chaim, volume III Responsa 93.) But if they are able to sit in a sukkah without too much trouble, they are obligated to do so. At night, when they are at the lodging where they intend to stay overnight, they must make an effort to [find] a sukkah in which to dwell. Even if they are in a place where there is no sukkah, if they can make one at a small cost,²¹This is not an actual obligation but those who do so will be blessed. If you intend to remain at any one place for three or four days, you must then make a sukkah. (Ibid 640:44) they must endeavor to have a sukkah for sleeping. If they are also traveling at night they are governed by the same Halachos that apply in the daytime. People who travel to villages on Chol Hamoed to collect debts, and cannot make a sukkah there, must assume the inconvenience of returning home every night in order to fulfill the mitzvah of sukkah.
