Where is parking absolutely prohibited?

Parking is absolutely prohibited in a crosshatched (diagonal) pattern space. These spaces are specifically designed to indicate areas where parking is not allowed, often due to safety concerns or to ensure clear access for emergency vehicles and pedestrians. The crosshatched markings serve as a visual cue to drivers that stopping or parking in that area could obstruct traffic flow or access to important infrastructures, such as driveways or pedestrian crossings.

In contrast, while parking in front of fire hydrants is also illegal, the prohibition exists primarily because it can hinder firefighters' ability to access water in emergencies. Parking on public highways can be restricted but may not be absolutely prohibited in all circumstances, such as along specified sections where parking regulations may vary. Similarly, loading zones are designated for temporary parking for loading and unloading purposes, and while misuse may lead to penalties, they are not universally prohibited for parking.
