“The Messenger of Allah ﷺ prescribed two Rak’ah of prayer when traveling; they are complete and are not shortened. And Witr when traveling is Sunnah.” (Using translation from Ibn Mājah 1194)

عَنِ ابْنِ عُمَرَ وَابْنِ عَبَّاسٍ قَالا سَنَّ رَسُولُ اللهِ ﷺ الصَّلاةَ فِي السَّفَرِ رَكْعَتَيْنِ وَهِيَ تَمَامٌ وَالْوَتْرُ فِي السَّفَرِ سُنَّةٌ
