How does checking the position of another vehicle's tires help you while driving?

Checking the position of another vehicle's tires is an important skill in defensive driving as it provides valuable insights into the driver's intentions. When observing the angle and direction of another vehicle's front tires, you can make educated predictions about where that vehicle is likely to go. For instance, if the tires are pointed toward the road you are on, the vehicle is likely preparing to turn into your lane or change its direction. This can significantly enhance your situational awareness and preparedness for any potential hazards or changes in traffic flow.

In contrast, calculating fuel efficiency or determining the vehicle's speed requires other methods and does not directly relate to tire position. Similarly, checking for traffic signs is vital for obeying road regulations but is not influenced by the observation of a vehicle's tire position. Thus, understanding tire orientation is primarily crucial for anticipating other drivers' maneuvers and maintaining safe distances while on the road.
