Under what condition may you cross or enter a public road?

Crossing or entering a public road is primarily determined by the clarity and safety of the situation. When the road is clear of traffic for a long distance, it indicates that there are no immediate hazards or vehicles that could pose a risk while crossing. This condition allows for a safe maneuver, reducing the likelihood of accidents.

In contrast, congested traffic may hinder visibility and slow down response times, making crossing more dangerous. Similarly, while traffic signals provide important directives for when to proceed onto a road, being clear of traffic is a more fundamental criterion. Additionally, the one-way nature of a street does not inherently guarantee safety for crossing; rather, it is just about the direction of vehicles on that road. Therefore, the option that emphasizes clarity and the absence of traffic provides the most appropriate condition for crossing safely.
