Four-way stop accidents can be one of the most dangerous kind of traffic collisions. Four-way stops, also knon as all-way stops, are intersections that have stop signs controlling all four sections of road where they cross or converge. Four-way stops are the site of thousands of car accidents each year and are designated ‘high crash areas’. Drivers that fail to stop or are confused about four-way stop rules can easily cause a deadly accident.
Four-Way Stop Accident Impact: Broadside, Side-Impact, Right-Angle, T-Bone
Crashes at four-way stops can be very serious. These are typically broadside collisions, also known as side-impact, right-angle or T-bone collisions, in which the side of one vehicle is impacted by the front or rear of another vehicle, forming the "T".
Studies have shown that side-impact crashes account for 13% of all car accidents and 18% of all fatal car accidents. These t-bone impact collisions often result in brain injuries, pelvic and torso injuries, and spine and neck injuries.
Four-way Stop Accident Statistics
According to a study conducted by the Insurance Institute for Highway Safety revealed that traffic accidents that involved a stop sign violation accounted for 70% of all motor vehicle crashes. Approximately one-third of these collisions result in injuries to either a vehicle driver, passenger or pedestrian.
