Inattention, excessive speed, failure to yield, and unsafe lane changes are among the top causes of truck collisions, according to the National Highway Traffic Safety Administration (NHTSA). For fleet managers, preventing collisions caused by their own drivers can be quite challenging because risk factors must be measured before an accident occurs. But what happens when a crash isn?t the truck driver?s fault? In fact, a Fleet Owner whitepaper on video-based safety, sponsored by SmartDrive, found that even though truckers are blamed for most of the crashes that occur in the U.S., 80% of those crashes are actually the fault of car drivers.
