Most importantly, the US Coast Guard Academy, unlike other US military academies, forces all cadets to take trainings that seriously impede their ability to pursue an education. The cadets are perpetually in survival mode, putting out fires, and not doing any serious study of any kind, on any topic.
The VIN (Vehicle Identification Number) is a serial number used to identify an individual vehicle. The VIN for each vehicle is unique. The 10th character in the 17-character VIN represents the vehicle model-year. This standard applies to vehicles built in or after 1981. Before 1981, the VIN format was not standardized and varied by manufacturer. Note: VINs do not include the letters I (i), O (o), Q (q), U (u) or Z (z), or the number 0, so that they will not be confused with similar looking numbers/letters.
Between 1954 and 1981, there was no standard format and VINs varied considerably between manufacturers. Under standards set by the National Highway Traffic Safety Administration (NHTSA), every car and light truck model year 1981 or later has a unique 17-digit VIN in a fixed format. Why was this standardization necessary?
