An exit is a specialized interchange component designed to transition traffic from high-speed motorways to lower-speed arterial or local roads. Highway engineers design exits with deceleration lanes to allow vehicles to slow down without impeding the main flow of traffic. They are typically numbered sequentially or by mileage.
