Which of the following is necessary for parking legally on public streets?

Parking legally on public streets requires following posted parking signs because these signs provide the specific regulations and restrictions that dictate where, when, and under what conditions parking is allowed. They serve as essential guides for drivers, indicating parameters such as time limits, fees, permit requirements, and restrictions that may apply to certain vehicles or times of day.

For example, a sign might indicate that parking is permitted only during specific hours or that certain days of the week have alternate side parking rules for street cleaning. Complying with these signs ensures that drivers do not face fines, towing, or other legal repercussions for improper parking.

While designated areas, permits, and the ability to park at any time may be relevant to certain scenarios, the critical requirement for legal parking in public spaces revolves around adherence to the specific instructions provided by posted signage. Therefore, understanding and respecting these signs is fundamental to responsible vehicle operation and parking practices.
