4NTSB Recommendation -
- The National Transportation Safety Board (NTSB)
has formally proposed that automobile
manufacturers equip their products with recorders
capable of storing crash data that could help
develop a safer national transportation system.
The Vetronix CDR System helps further the NTSBs
recommendation by creating a product that
downloads the data stored in recordable airbag
modules.
