What is the main way to exit an expressway?

The main way to exit an expressway is through an exit ramp. Exit ramps are specifically designed to facilitate a safe transition from the high-speed expressway to local roads or different routes. These ramps typically have lower speed limits and are marked clearly in advance to prepare drivers for the upcoming turn-off. This design helps prevent abrupt stops or dangerous maneuvers that could occur if drivers were to exit without a designated ramp.

Other choices may refer to types of roadways or connections, but they do not serve as the dedicated and intended points for exiting an expressway. Consequently, exit ramps are purposefully constructed to ensure safe and efficient movement from one road system to another.
