When a crash involves a young driver losing their life after rear-ending a stopped vehicle, it’s tempting to assume the cause is straightforward—distraction, inattention, or simple driver error. But over the years, I’ve learned that the only way to truly understand what happened is to ask the right questions and follow the evidence wherever it leads. In this case, like every serious crash, there are three critical questions that need to be answered.

First, did the authorities thoroughly investigate the crash? Initial reports indicate that a Mazda CX-5 struck the rear of a stopped Ford F-250 on Route MM, but they don’t explain why. A comprehensive investigation should include documentation of skid marks, damage patterns, vehicle positions, and sightline analysis to understand whether the Mazda driver had any opportunity to avoid the collision. Investigators also need to determine whether traffic conditions changed suddenly or if other external factors played a role. The quality of this analysis depends heavily on the training and resources available to the agency handling the investigation—something that varies widely from one department to another.

Second, has anyone considered whether a vehicle defect might have contributed to the crash? While rear-end collisions are often attributed to inattention, that assumption can obscure other potential causes. For example, a brake failure or a malfunction in the Mazda’s adaptive cruise control or collision avoidance system could explain the lack of response before impact. These systems are designed to prevent exactly this type of crash, but they can and do fail. Unfortunately, unless someone preserves the vehicle and initiates a forensic inspection, these types of defects can go undetected and uninvestigated. That’s a major reason why maintaining control of the vehicle after a crash is so important.

Finally, has all the electronic data relating to the crash been collected? Modern vehicles like the Mazda CX-5 and Ford F-250 are equipped with engine control modules (ECMs)—commonly referred to as “black boxes.” These devices can store valuable information such as speed, braking input, throttle position, and steering angle in the moments leading up to a crash. Additionally, phone records, dashcams, and any nearby surveillance footage can offer insight into what the driver saw, how much time they had to react, and what may have caused the delay in response. This kind of data is perishable. If it isn’t preserved early in the process, it may never be recovered.

No one expects to lose a loved one in a morning commute, and while this investigation is still ongoing, it’s essential that it includes a full accounting of these three areas. Without answers to these questions, we risk misunderstanding what really happened—and missing opportunities to prevent similar crashes in the future. The community owes it to the young man who lost his life and to his loved ones to find out not just that a crash occurred, but why it did.
