What does a 'No Parking' sign mean?

A 'No Parking' sign indicates that parking is prohibited in the area where the sign is displayed. This restriction is often put in place to keep roadways clear for traffic, emergency vehicles, or to ensure that essential access is maintained for various purposes, such as fire lanes or loading zones. The presence of this sign means that any vehicle found parked in violation of this rule could be subject to fines or towing.

The other choices imply possible exceptions or allowances that are not provided for under a 'No Parking' sign. For example, briefly parking or loading and unloading might typically be allowed where signs indicate it, but a 'No Parking' sign clearly states that such actions are not permitted in that specific area, making the absolute nature of this sign crucial for compliance and safety.
