The term 'cloverleaf component' refers to two parts of a highway interchange. An EXIT is a four-letter word that describes a point on a highway where vehicles can leave the roadway. An onramp is a six-letter word that describes a section of a highway where vehicles can enter the roadway. Together, these two components form a cloverleaf interchange, which is a type of highway junction that allows vehicles to enter and EXIT the highway in a safe and efficient manner.
