When a drunk driver is involved in an accident and it doesn’t matter if it’s a car accident, a motorcycle accident, pedestrian or cycling accident, it’s what they did that causes them to be at fault. That could be speeding, running a red light, changing lanes, or running off the road. So, they are responsible. Lawyers would say they are liable for what they did that caused the accident.
The drunk driver is negligent and you hold them responsible through a civil case, through the claim that your lawyer would bring typically against the drunk driver’s insurance company. They would be held responsible for what they did that caused the accident and they are required and obligated under the law to pay you for everything that the accident has done to you from the pain and suffering, disability, disfigurement, loss of the enjoyment of life and all of the out of pocket expenses from medical to lost wages.
