A dual-clutch transmission includes first and second partial transmissions, a first countershaft to which a first output gear is permanently connected in a rotationally fixed manner, and a second countershaft to which a second output gear is permanently connected in a rotationally fixed manner. A first idler assigned to the first partial transmission and a second idler assigned to the second partial transmission are respectively arranged coaxially to the first countershaft and are couplable to each other in a rotationally fixed manner by a bridge switching element. The first partial transmission includes exactly three single-gear planes, including a first single-gear plane, second single-gear plane having the first idler, and third single-gear plane. The second partial transmission includes exactly two single-gear planes, including a fourth single-gear plane having the second idler and a fifth single-gear plane, and which is equipped such that eight transmission gears can be implemented with a falling transmission ratio.
