When driving in the left lane, you must move right to allow traffic to pass because the left lane is usually reserved for passing slower vehicles. Staying in the left lane for as long as possible (B) can create a hazard for other drivers and slow down the flow of traffic. Driving faster than other vehicles (C) is not required and can be dangerous, as it can lead to speeding and potential accidents. Remaining in the left lane at all times (D) is also incorrect, as it can impede the movement of faster vehicles and is not the proper use of the left lane.
