A large truck is driving in the middle of a three-lane road. What is the best way to pass the large truck?

The right lanes on a free way is used to exit and enter the traffic. It is used at the beginning and end of freeway run. The middle lane of for running traffic. If a person wants to change lanes he/she must use the left lane. If you are not passing someone then you shouldn't drive in the left lane.

We can pass the truck by shifting to the left lane and the again shifting to the middle lane.
