What is the safest way to pass through an intersection?

The correct answer is:
All of the above options are correct.

New Zealand's traffic rules are designed to ensure the safety of all road users. Understanding and adhering to these rules can reduce the likelihood of accidents and protect the safety of oneself and others. Extra caution is needed when passing through intersections, as these are among the most common places for traffic accidents to occur.

1. Observe to the left - In New Zealand, driving is on the left side of the road, so it is equally important to watch for vehicles coming from the left at intersections.
2. Observe to the right - Since New Zealand follows left-hand traffic rules, vehicles coming from the right may be the main flow of traffic and must be given the right of way.
3. Observe the road conditions ahead - Ensuring that there are no obstacles or pedestrians crossing at the intersection and ahead is crucial for safe passage through intersections.
4. Observe vehicles behind - Knowing whether there are vehicles following behind and their distance can help drivers safely slow down or stop while waiting to cross.

Comprehensive observation of vehicles and road conditions from all directions is key to safely passing through intersections. This not only helps prevent traffic accidents but also improves traffic flow, reducing congestion and delays caused by traffic violations. Additionally, adhering to traffic rules can help avoid fines or other legal consequences for violations. Therefore, understanding and practicing these safety measures is the responsibility of every driver to ensure the safety and well-being of all.
