Which of the following actions demonstrates successful preventable collision avoidance?

Using turn signals appropriately is a key aspect of effective communication between drivers on the road. It signals your intentions to others, making them aware of your upcoming maneuvers, such as turning or changing lanes. This practice is essential for preventing collisions, as it provides drivers and pedestrians with crucial information, allowing them to react accordingly.

When drivers use turn signals, it helps create a predictable environment, reducing the chances of misunderstandings and accidents. Proper signaling fosters a safer driving culture, as it ensures that all road users are aware of each other's intentions. This proactive communication is fundamental to achieving successful preventable collision avoidance.

On the other hand, some actions mentioned are less effective in contributing directly to collision avoidance. Ignoring traffic signals can lead to chaotic conditions and increase the likelihood of accidents. Logging frequent vehicle maintenance is important for ensuring the overall safety and performance of a vehicle, but it does not directly influence the actions of other drivers on the road. Pacing behind the vehicle in front can help maintain a safe distance but does not actively inform others of your driving intentions, which is critical in preventing collisions.
