Final answer:
When parking on a two-way street without curbs, one should park close to the edge of the road to ensure smooth traffic flow and enhance safety for all.
Step-by-step explanation:
When parking on a two-way street without curbs, the correct practice is to park as close to the edge of the road as possible. Parking close to the edge facilitates smoother flow of traffic and minimizes the likelihood of accidents. It is important not to park on the sidewalk, if one is present since this can obstruct pedestrian pathways and is often illegal. Moreover, parking in a manner that avoids obstructing the flow of traffic helps ensure pedestrian safety as there would be a clear view for those crossing the road, and drivers won’t have to swerve around improperly parked cars which could create risky situations.
