Collision Avoidance refers to a system or technology used in vehicles, aircrafts and other modes of transportation that helps prevent accidents by detecting potential collisions and taking evasive action. This can include various sensors such as radar, lidar, cameras, and ultrasonic systems which are designed to detect obstacles and warn the driver or pilot in advance so they can take corrective actions to avoid a collision. Collision Avoidance technology is an essential safety feature that helps prevent accidents on roads, airports, and waterways.
