What is a major cause of accidents at intersections?

Answer: B — Failing to yield the right of way

Failing to yield the right of way is a significant cause of accidents at intersections because it often leads to collisions between vehicles that have the right to proceed. In many intersection scenarios, one driver may assume they can move through the intersection without checking for other vehicles, resulting in dangerous conflicts. When drivers don't yield as required by traffic laws, it disrupts the expected flow of traffic and can quickly lead to misunderstandings and accidents. In contrast, while excessive speed, driving under the influence, and ignoring traffic signals all contribute to potentially dangerous driving behaviors, the specific action of not yielding often creates the most immediate risk in the context of intersections. This is particularly true in situations where multiple roadways converge, requiring all drivers to adhere closely to right-of-way rules to ensure safety. Addressing right-of-way violations is crucial in promoting safer driving practices at intersections.
