When determining fault, it's often important to ask what happened leading up to the auto accident. From bad-driving behaviors to disobeying rules of the road to poorly designed intersections, here's what often causes car accidents: Aggressive Driving ​- This occurs when someone is driving in a hostile manner with little regard to other drivers on the road. This often leads to tailgating, unsafe lane changes, failing to yield or signal, speeding, and general disregard for traffic regulations. Complicated Roadways - These are roads with unusual features, such as unexpected curves, narrow lanes, missing or damaged road signs, and challenging to navigate roadways. Distracted Driving - Distracted driving happens when the driver is not paying attention or takes their eyes off the road, even if for a second. This can happen when the driver tries to change the radio, is eating, texting, or talking on the phone. Drowsy Driving - If you are driving while cognitively impaired due to being sleep deprived, you are considered to be driving while drowsy. Drugged Driving - Drugged driving happens when you are driving the influence of recent drug use. This can include both legal and illegal substances. Drunk Driving - Driving under the influence of alcohol can increase your chances of being in an accident. If you are driving while intoxicated, even if you are under the legal limits, your judgment and response time can be impaired.
