You may not park your car in any of the following places, except:

Parking regulations are designed to maintain safety and accessibility on the roads. Parking on the side of a street is generally permissible unless there are specific signs or markings that indicate otherwise. This option is valid because many residential and commercial streets allow for parking along the sides, provided it does not obstruct traffic flow or violate local ordinances.

On the other hand, parking in front of a fire hydrant, in a no-parking zone, or in a crosswalk can significantly impede emergency services, pedestrian access, and overall traffic safety. These practices are usually prohibited to ensure that emergency vehicles can access hydrants quickly and that pedestrians can navigate safely across streets.
