At what distance should you start to turn on your turn signal before exiting the highway?

Answer: B — At least 500 feet

The correct answer is that you should start to turn on your turn signal at least 500 feet before exiting the highway. This practice is important for safety as it provides ample notice to other drivers that you intend to make a lane change or exit. Signaling well in advance gives surrounding vehicles enough time to react appropriately, reducing the likelihood of accidents. On highways, where speeds are typically higher, allowing a longer distance for signaling is crucial. This helps ensure that you communicate your intentions clearly and effectively, contributing to a smoother transition off the highway and enhancing overall road safety. While shorter signaling distances might suffice in some situations, 500 feet is a recommended guideline to promote proactive driver awareness and prevent any misunderstandings that could lead to unsafe conditions.
