When in doubt about a traffic sign, what should you do?

Answer: B — Slow down and look for additional information or signals

When encountering uncertainty about a traffic sign, it is crucial to prioritize safety and make informed decisions. Slowing down allows you time to better assess the situation, read the sign more carefully, and look for any additional information or signals that might provide clarity. This approach helps ensure that you fully understand the traffic regulations in place and can respond appropriately to them. Additionally, maintaining a measured pace also helps minimize risks for you and other road users, as it gives them time to react to your movements. Quickly attempting to speed through an intersection, ignoring the sign, or abruptly changing lanes can lead to dangerous situations, accidents, or traffic violations. Hence, taking time to slow down and obtain all necessary information is the most responsible action when faced with ambiguity regarding traffic signs.
