Which of the following is a proper response to road signs indicating a turn?

The correct response involves signaling and reducing speed before making a turn. This is a crucial part of safe driving practices and ensures that you communicate your intentions to other road users. By signaling in advance, you give other drivers, cyclists, and pedestrians adequate notice of your turn, allowing them to adjust their behavior accordingly. This can help prevent misunderstandings and potential accidents.

Reducing speed before the turn is equally important because turns can change the dynamics of vehicle handling. A slower approach allows for better control of the vehicle and decreases the likelihood of losing traction or misjudging the turn's curvature. This combination of signaling and speed adjustment leads to safer driving conditions for everyone on the road.

The other choices do not align with safe driving practices. Waiting until the last moment to signal can confuse other drivers and increase the risk of an accident. Ignoring signs, regardless of traffic conditions, is unsafe as it disregards established road rules and could lead to dangerous situations. Only signaling if other vehicles are present also fails to account for pedestrians and cyclists who may not be immediately visible but are still impacted by your turn. Thus, the correct approach truly embodies proactive and responsible driving behavior.
