Is it permissible to pass another vehicle on a hill if they are in the right lane?

The correct response highlights the importance of safety and adherence to traffic regulations regarding passing maneuvers on hills. Passing another vehicle while traveling uphill is generally considered dangerous because visibility is often limited; drivers may not have a clear view of oncoming traffic or any obstacles. Hills can create blind spots where the driver cannot see whether the road is clear ahead, increasing the risk of a collision.

Additionally, most regulations prohibit passing on hills or curves, reinforcing the focus on safety. Even if another vehicle is in the right lane, choosing to pass in such circumstances could result in severe accidents.

The other options suggest varying degrees of permissibility regarding passing on hills, but they don't take into account the essential safety considerations and legal restrictions that exist for such maneuvers, affirming that the choice emphasizing the dangers of passing on hills is the most reliable one.
