In most frontal crashes, the primary factor contributing to the incident is a lack of adequate margins to the front of the vehicle. When a driver is unable to maintain a safe following distance or inappropriate speed, they can quickly find themselves unable to stop in time to avoid a collision with an object, another vehicle, or an obstacle ahead.

When the emphasis is on having sufficient space in front, it allows for adequate reaction time in emergencies, such as sudden stops or slow-moving traffic. This concept is critical in defensive driving, as drivers need to be aware of the space they have available ahead of them. A good rule is to keep a distance of at least three seconds from the vehicle in front to provide ample time to react.

Therefore, the focus on the front of the vehicle is essential to understanding the dynamics of frontal crashes, as these usually involve scenarios where the driver misjudges the distance needed to safely navigate, leading to collisions that could have been avoided with proper spacing.
