What is cumulative risk in the context of driving?

Cumulative risk in the context of driving refers to the concept that as a driver is exposed to various risks—such as driving more frequently, facing challenging weather conditions, or engaging in more complex traffic situations—the overall probability of being involved in an accident increases. Each exposure adds to the risk level, and these risks can accumulate over time. This understanding emphasizes the importance of being aware of how different contributing factors can elevate the likelihood of an accident, even if individual risks might seem manageable when considered in isolation.

The focus on the accumulation of risk underscores the necessity for drivers to reflect on their driving habits, environments, and decision-making processes, as these can compound to create a more dangerous situation over time. By recognizing cumulative risk, drivers can take preventative measures to mitigate potential hazards, such as practicing defensive driving, adhering to safety guidelines, and choosing safer routes or driving conditions.
