What must the driver of vehicle 2 observe when proceeding at an intersection?

The driver of vehicle 2 must observe the right-of-way rules applicable to the intersection scenario. In this case, the correct choice is to give way to the right-of-way of vehicle 1, presuming here that vehicle 1 has the right-of-way according to traffic regulations at the intersection.

In any intersection scenario, right-of-way is crucial for maintaining safety and orderly flow of traffic. Adhering to these rules helps prevent accidents and ensures that vehicles navigate through intersections based on established traffic laws. The confusion here seems related to the interpretation of which vehicles are considered to have priority.

Giving the right-of-way to the appropriate vehicle (likely vehicle 1 in this context) is fundamental for safe driving practices, as it promotes predictability in the actions of drivers at intersections. Understanding and applying right-of-way rules are essential parts of safe driving and should always be the focus when navigating through areas where multiple vehicles converge.
