Thats how i travel in multi lane highways. Always believed the center was the safe and correct lane. Don't remember anything on my test about 3 lanesI drive below the speed limit every day on I70 headed to downtown. I leave early and try to relax while taking my time getting to work. I want that trip to be nice and slow. For me riding in my car either listening to music or praying is more calming than being in a hurry to get to work.
But, there are three lanes going in my direction. I stay in the middle which leaves the right lane for all vehicles entering or exiting the highway and the left lane for those whom wish to go fast.
