On a five-lane highway, if you are in the far left lane and must exit to the far right, how many lane changes are required to reach the rightmost lane?

Answer: C — 4 lane changes

The number of lane changes you need equals the number of lane boundaries you have to cross. Starting in the far left and moving to the far right across five lanes means you must pass through four adjacent lanes: leftmost to the second, then to the third, then the fourth, and finally into the rightmost lane. You can’t jump over more than one lane at a time, so four lane changes are required. On a five-lane highway, that’s the maximum needed for moving from edge to edge. As you change lanes, remember to signal, check mirrors, and look for vehicles in your blind spots before each move.
