What must be checked regarding the turn signals?

Turn signals are a crucial safety feature on any vehicle, ensuring that other drivers are aware of your intentions. For a thorough pre-trip inspection, it is essential that these signals are not only functioning properly but also meet specific color and visibility standards. The correct answer emphasizes that turn signals should be clear or amber and in working order. This is in alignment with road safety regulations, as these colors are standardized to convey the correct message to other drivers.

If the turn signals are not working or if they do not meet the color requirements, it could lead to misunderstandings on the road, increasing the risk of accidents. Ensuring that they are operational and adhere to color specifications is a vital part of maintaining vehicle safety. Other options tend to either misinterpret the requirements for turn signals or focus on non-essential characteristics, which are not relevant during a pre-trip inspection.
