Final Answer:
When following another vehicle, you must use your Turn signals, if you are within 50 feet of the vehicle ahead of you. Thus option B is correct.
Explanation:
When driving, it's crucial to maintain a safe distance behind the vehicle ahead to ensure safety and allow for reaction time. According to traffic regulations, the use of turn signals is mandated when within 50 feet of the vehicle in front. This distance is approximately the recommended stopping distance at moderate speeds, offering ample reaction time in case the lead vehicle makes sudden movements or stops abruptly.
The rationale behind the 50 feet requirement is rooted in safety standards. At an average speed, a car would typically need around 50 feet to come to a complete stop when the brakes are applied. Therefore, within this range, using turn signals becomes imperative to indicate intentions to the driver behind and ensure a safe driving distance.
Following this mandated distance and using turn signals within 50 feet helps in preventing rear-end collisions, allowing for smoother traffic flow, and providing clear communication between drivers. This distance is a practical measure to maintain safe driving practices and minimize the risk of accidents, thereby emphasizing the importance of adherence to traffic regulations for everyone's safety on the road.Thus option B is correct.
