A jughandle is a type of ramp or slip road that changes the way traffic turns left at an at-grade intersection (in a country where traffic drives on the right). Instead of a standard left turn being made from the left lane, left-turning traffic uses a ramp on the right side of the road. In a standard forward jughandle or near-side jughandle, the ramp leaves before the intersection, and left-turning traffic turns left off of it rather than the through road; right turns are also made using the jughandle. In a reverse jughandle or far-side jughandle, the ramp leaves after the intersection, and left-turning traffic loops around to the right and merges with the crossroad before the intersection.

The jughandle is also known as a Jersey left due to its high prevalence within the U.S. state of New Jersey (though this term is also locally used for an abrupt left at the beginning of a green light cycle).^[1] The New Jersey Department of Transportation defines three types of jughandles. "Type A" is the standard forward jughandle. "Type B" is a variant with no cross-street intersected by the jughandle; it curves 90 degrees left to meet the main street, and is either used at a "T" intersection or for a U-turn only. "Type C" is the standard reverse jughandle.^[2]
