A car barrier includes two posts and a central net is connected between the two posts. Two side nets are slidably connected to two ends of the centr al net. The central net has a first top rail and a first bottom rail, and each of the side nets has a second top rail and a second bottom rail. At least one positioning unit has a connection member which includes two passages defined therethrough. The first bottom rail and the second bottom rail respectively extend through the two passages. The second bottom rails can be slid with in the passages so as to adjust the width of the car barrier.
