All the cars turn through that the cars will not clash with each other..since all cars are coming in the same speed there is a possible of clashing each other..but when they all turns to the same direction there may be chances to avoid the clash between the cars.. Source:

There is one answer which will always work. Of the other two, one or the other will work, but it depends on the country you are driving in.

#3, with two cars turning left and two turning right, will always work. The requirement is that the driver approaching north and south will turn in the same direction, and the driver approaching east and west will turn the opposite direction. So if North and South turn to the right, East and West must turn left.

#1, all drivers turn left, will work in countries where drivers drive on the left side of the road. However, as I live in the United States, this would be disasterous.

#2, all drivers turn right, will work in countries where drivers drive on the right side of the road. In the United States, in many intersections you may make a right turn while the traffic light is red.

Three salesmen went into a hotel to rent a room. The manager stated that he had only one room left, but all three could use it for $30.00 for the night. The three salesmen gave him $10.00 each and went up to their room. Later, the manager decided that he had charged the salesmen too much so he called the bellhop over, gave him five one-dollar bills, and said: 'Take this $5.00 up to the salesmen and tell them I had charged them too much for the room'. On the way up, the bellhop knew that he could not divide the five one-dollar bills equally so he put two of the one-dollar bills in his pocket and returned one one-dollar bill to each of the salesmen. This means that each salesman paid $9.00 for the room. The bellhop kept $2.00. Three times nine is 27 plus two is 29....... What happened to the extra dollar?
