According to figures from the National Highway Traffic Safety Administration (NHTSA), out of the 6 million car accidents that happen on U.S. roads every year, over 40% of them (2.5 million) are rear-end collisions.
On average there is another rear-end collision every 8 seconds, which means that by the time you have read this sentence there has already been another one or two.
Running into someone in a rear-end accident is considered the most preventable accident there is. But so is backing, and drunk driving, and every other type of accident, depending on who wants to make which points about accidents. Some will even say that all accidents are preventable. That's a very Zen way of looking at accidents. Even Landline Magazine flatly states, "All accidents are preventable if a driver operates at a speed that is reasonable for the current road, weather and traffic conditions."
All accidents are predictable and preventable, because all accidents occur because someone did something, or failed to do something, which caused a predictable accident. Sometimes it's both, like, you're driving on bald tires, one blows out, you wreck the car. You failed to replace bald tires and then intentionally drove on them.
6 million car accidents on U.S. roads every year. Statistics dictate that accidents will happen, and with great frequency. Therefore, no accident is preventable as long as people are involved. So, if you are ever charged with a preventable accident, show them the statistics that prove the accident was inevitable, and thus thoroughly unpreventable.
Hey, might as well. Beats being charged with a preventable while you were parked and sleeping in your bunk (which has happened).
