Drunk driving accidents may happen for several reasons. Drunk drivers struggle with many challenges that may make them more dangerous on the road, including: Difficulty with tunnel vision or blurred vision. Frequently, drunk drivers have difficulty perceiving what takes place around them, which may increase the odds that they will completely miss the presence of a hazard that could interfere with their progress on the road. Slowed reaction times. Drunk drivers frequently struggle to react properly to the situations they may face on the road. Decreased reasoning skills. Frequently, drunk drivers will engage in risky behaviors that they would not change if not inebriated. Unfortunately, very intoxicated drivers may fail to recognize the dangers they present. Unpredictable behavior. Often, other drivers will struggle to predict what drunk drivers will do next, which raises the odds that the drunk driver will end up involved in a serious accident. Coordination problems. In many cases, drunk drivers will struggle to control their vehicles at all due to decreased overall coordination. Unfortunately, drunk drivers often end up in deadly collisions with other drivers, many of which can cause severe injuries.
