Final answer:
Road signs help drivers navigate and make safe decisions. An 'Exit Only' sign requires you to exit if you're in that lane, whereas an 'Optional Exit' sign allows you to exit or continue straight. Observing the sign's symbols and wording provides the necessary context to interpret it correctly.
Step-by-step explanation:
Understanding road signs is crucial for safe driving, and interpreting them correctly is a key skill. If a sign indicates 'Exit Only', it means that if you stay in that lane, you must take the exit - there's no option to continue on the current path. However, if it is an 'Optional Exit', you may use the lane to exit or to continue on the road. To determine which type of exit sign is being displayed in the photograph you referenced, one must closely observe the sign's symbols, wording, and context. For example, if an exit sign includes an arrow that splits off with another arrow continuing straight, it may imply an optional exit. Conversely, an arrow that points solely to the right or left without a straight option usually designates an 'Exit Only' lane.
