Why should you never pass on a curve or hill?

Answer: B — Because it causes many collisions

When considering the safety of passing on curves or hills, it is crucial to understand that these areas often reduce visibility and can create dangerous situations. Passing on a curve or hill impairs your ability to see oncoming traffic, and other drivers may not see you until it’s too late. This lack of visibility significantly increases the risk of collisions, especially if another vehicle is approaching from the opposite direction. Moreover, the dynamics of these road features can lead to more severe accidents due to the unexpected nature of a driver suddenly changing lanes in a limited visibility situation. This makes passing in such locations particularly hazardous and contributes to a higher incidence of traffic accidents. The safety of all road users relies on adhering to proper driving practices, which strongly discourage passing in environments that present such risks. In contrast, while legality may play a role in passing rules, the emphasis should primarily be on safety and traffic flow. The nature of curves and hills alone does not determine their legality for passing; rather, it is the increased potential for accidents that highlights why such maneuvers should be avoided.
