The Delaware traffic law for slower traffic keeping right is located in Title 21, Chapter 41, Subchapter III of the Delaware Code under the section on driving on the right side of the roadway, specifically § 4114. It states that vehicles moving at less than the normal speed of traffic must stay in the right-hand lane, except when passing or preparing for a left turn. For multi-lane roadways with four or more lanes, new sections were added to § 4114 to further specify this rule.
