In what scenario is it permissible to park on a public road?

Parking on a public road is permissible when there are no signs prohibiting parking. This means that the absence of explicit regulations allows drivers to use their judgment to park responsibly. It's essential to understand that public roadways can have various rules and parking restrictions that are signaled by signs, and when these are not present, it indicates that parking is allowed.

In other situations, such as parking in front of a driveway or in a bus stop zone, these actions are usually restricted because they can obstruct access and cause inconvenience to others. Parking on a corner may also pose visibility issues for other drivers, leading to unsafe driving conditions. Therefore, the key factor for lawful parking in the absence of restrictions is being vigilant and aware of applicable road signs.
