Ferry accidents occur when passenger or vehicle ferries collide, capsize, or experience mechanical failures, leading to injuries or fatalities. These incidents can happen due to various factors, including rough weather, human error, or overcrowding. Safety regulations are in place to minimize risks, but accidents can still occur. In many cases, ferry accidents prompt investigations by maritime authorities to determine causes and improve safety measures. Notable incidents, such as the MS Estonia disaster in 1994, highlight the importance of proper maintenance and emergency preparedness for ferry operators to protect passengers and crew.
