Trial court admitted evidence from the Qualcomm OmniTRACS system--messages and positioning data--that showed how far and how long the truck driver had driven in the 48 hours leading up to a crash (in violation of the FMSCA 11-hour and 14-hour rules). The positioning data showed his truck's almost exact latitude and longitude, which changed over time during the period in which he claimed he was sleeping. The evidence was also offered to impeach the truck driver, who had lied about this issue on his driver's logs, to the police in a sworn written statement, and repeatedly at his deposition in the personal injury action.
