What is the most important rule of physics to remember during driving emergencies?

The most important rule of physics to remember during driving emergencies is related to the dynamics of steering versus braking. In a critical situation, quickly steering your vehicle can often be more effective than braking, especially when trying to avoid an obstacle. The momentum of the vehicle means that it may take a significant distance to bring the vehicle to a complete stop if you choose to brake instead of steering.

This principle emphasizes the importance of maintaining control over the vehicle’s direction. By steering, you can navigate around obstacles and mitigate the risk of a collision. Braking, while it is essential in many driving scenarios, can lead to sliding or loss of control on slick surfaces, making steering out of danger the more advantageous choice in emergencies. Understanding these concepts enhances your ability to react appropriately when faced with unexpected situations on the road.
