Although car accidents are more commonly thought of as involving two vehicles or more, there are instances where only one vehicle is involved. Single-vehicle accidents are car accidents involving just one vehicle, although these accidents can involve multiple passengers in the car or involve pedestrians or bystanders. Common reasons for single-vehicle accidents include driving at a high speed, driving while under the influence, distracted driving (such as texting while driving or taking your eyes off the road), inclement weather leading to lack of visibility or poor road conditions, and mechanical issues. In some situations, a vehicle may not collide with another vehicle but may attempt to avoid a collision, which may result in a single-vehicle accident.
