When should the Medical Advisory Board (MAB) box be selected on the CR-3?

The Medical Advisory Board (MAB) box should be selected in situations where a driver's physical condition may have played a role in the traffic incident. This is particularly relevant when the driver was physically ill at the time of the accident, as such conditions can affect their ability to operate the vehicle safely. Including this information ensures that the appropriate authorities are aware of potential medical issues that could impact not just the driver but also the public's safety.

Selecting this option provides important context for any investigations or follow-ups, as it helps regulators assess whether medical conditions should lead to additional evaluations of the driver’s fitness to operate a vehicle. Such actions might be taken to prevent future incidents that could arise from similar health-related impairments.

In contrast, the other scenarios do not directly signal a need to consult the Medical Advisory Board. For instance, being under 18 or having a passenger injury does not necessarily relate to the driver's medical fitness at the time of the crash. Similarly, road conditions affecting the crash do not imply a medical issue with the driver, making them less relevant for selecting the MAB box.
