You must not use _________ to exit the freeway, even in a traffic jam.

Using a shoulder to exit the freeway is prohibited because shoulders are designed as emergency areas for vehicles that experience trouble, such as engine failure or tire issues. Exiting onto the shoulder can create additional hazards, not only for the vehicle that is leaving the highway but also for other drivers and emergency response vehicles that may need access to the shoulder. The primary purpose of the shoulder is to provide a safe space to stop in emergencies, not to function as an alternative route for exiting the freeway.

The other options, such as using a second exit, a service road, or a designated exit lane, are typically legal and intended for use in normal driving situations. A second exit may allow drivers to navigate traffic flow, a service road connects to businesses or residences parallel to the freeway, and designated exit lanes are specifically designed for smooth transitions off the freeway. These alternatives are structured to maintain traffic flow and ensure safety, unlike the shoulder, which is not meant for regular vehicular movement.
