Which of the following is a location where you should never park a vehicle?

Parking in front of a public or private driveway is prohibited because it obstructs access for residents and emergency vehicles. Doing so can create hazardous situations and lead to legal penalties.

Stopping within 20 feet of a crosswalk is also against the rules. This is intended to ensure visibility for both pedestrians and drivers, enhancing safety at intersections.

Additionally, parking within 30 feet of a flashing signal located at the side of the roadway is prohibited as well. This distance is necessary to maintain clear sight lines for approaching traffic, ensuring that drivers can see and respond to signals appropriately.

Each of these locations is clearly defined by traffic laws to promote safety and accessibility on the roadways, which is why all of these options represent locations where parking should be avoided.
