What is behind the vehicle most common cause of collision backing up while?

The most common cause of collisions while backing up is limited visibility, which can make it difficult for drivers to see objects, pedestrians, or other vehicles behind them. Additionally, distractions, such as mobile devices or passengers, can divert attention and increase the risk of accidents. Improper use of mirrors and failure to check blind spots also contribute significantly to these incidents. Implementing safety measures like rearview cameras and sensors can help mitigate these risks.
