This thesis examines and compares the risks associated with traffic accidents involving electric vehicles and conventional internal combustion engine vehicles. The study focuses on identifying key risk factors, differences in accident characteristics, and the severity of consequences, including fire hazards, battery-related risks, fuel-related hazards, and risks to passengers and emergency responders. The research applies risk assessment methodologies to evaluate the probability and impact of different accident examples. The objective is to determine whether the propulsion system significantly influences overall risk levels and to provide recommendations for improving safety measures and emergency response procedures. The results of the analysis show that electric vehicles cause much more severe consequences in certain traffic accident examples, mainly due to the greater mass of the vehicle and the characteristics of the battery systems. On the other hand, the probability of a fire is higher in conventional vehicles. It was found that the risk structure for both types of vehicles differs, with the severity of the consequences prevailing in electric vehicles and the probability of the event prevailing in conventional vehicles
