When is it acceptable to drive on the shoulder of the road?

Driving on the shoulder of the road is acceptable primarily in emergency situations or to allow other vehicles to pass safely. This practice is intended for specific scenarios, such as when your vehicle is disabled or when a larger vehicle needs to maneuver around you for safety reasons. Shoulders are not designed for regular driving and using them under conditions such as heavy traffic, attempting to bypass road construction, or while looking for an address can create dangerous situations, obstruct traffic flow, and may lead to accidents. Therefore, the correct choice emphasizes the safety and emergency context that justifies using the shoulder.
