Much of safe driving is concentrating on driving, avoiding distractions, and applying patience. Which lane is best to drive depends on traffic conditions. In general, on a two-lane parkway use the right lane for cruising (slower driving) and the left lane for passing. When there are three or more lanes, the right lane should be used by lower speed traffic, the left lane for passing, and the center lane for cruising.  Do not be distracted or slow down excessively to look at incidents in or near the roadway. This adds to congestion and increases the potential for additional incidents.
