According to the National Highway Traffic Safety Administration (NHTSA), data from 2018 shows that Texas had the highest number of car accident deaths with 3,541. This was followed by California with 3,602 and Florida with 2,935. The state of Texas accounted for 10.5% of all traffic fatalities in the United States last year. This is due in part to its long stretches of highways and rural roads combined with a high population density which leads to more cars on the road at any given time.The primary causes for these fatal accidents include impaired driving, speeding, distracted driving and failing to wear seatbelts or other protective gear while driving. With so many people not taking proper safety precautions when behind the wheel it is no wonder why this particular state has some of the most tragic numbers when it comes to vehicle-related fatalities on our nation's roads each year. It is therefore essential that everyone does their part in reducing these horrific figures by making sure they always drive responsibly and follow all applicable laws when operating a motor vehicle – especially if you live in or are visiting one of these states where such tragedies occur far too often!
