Where is parking prohibited?

Parking is prohibited at the edge of the roadway if doing so would block others from using designated parking areas, because this can create unnecessary obstructions and prevent others from parking or leaving safely. It is also not allowed to park before sunken kerbstones, as these are often used to allow access for wheelchairs, strollers, or delivery vehicles, and parking there would block this important access. Both of these rules help maintain smooth and safe traffic flow and ensure that all road users, especially those with special needs, are not hindered.
