What may speed need to be adjusted based on?

  1. Your mood

  2. Traffic conditions, road conditions, and visibility

  3. The time of day

  4. Nearby pedestrians

The correct answer is: Traffic conditions, road conditions, and visibility

Adjusting speed based on traffic conditions, road conditions, and visibility is crucial for safe driving. This consideration ensures that a driver can respond appropriately to changing circumstances on the road. For example, if traffic is heavy, the driver may need to reduce speed to maintain a safe following distance and avoid potential collisions. Similarly, adverse road conditions such as rain, snow, or ice can greatly impact vehicle traction, requiring a slower speed to manage control and avoid accidents. Visibility is another critical factor; during fog, rain, or night driving, decreased visibility can make it difficult to see other vehicles, traffic signals, and obstacles, warranting a slower pace to ensure safety. Therefore, being attentive and adaptable to these conditions enhances overall roadway safety and helps prevent accidents.
