Under what condition can you park or stop along the shoulder of the freeway?

Parking or stopping along the shoulder of the freeway is primarily allowed only in case of an emergency. This is crucial because the shoulder is meant to provide a safe space for vehicles to stop in situations where continuing to drive would be dangerous, such as mechanical breakdowns, medical emergencies, or other unforeseen incidents. Stopping for non-emergency reasons, like looking at a map, can create hazards for both the stopped vehicle and other drivers, leading to potential accidents. Consequently, ensuring that stopping is restricted to emergencies helps maintain safety and the flow of freeway traffic.
