Amazon is using a custom logging device to track the trucks moving its freight

Amazon has developed electronic tracking technology for the trucks used by its partners to monitor their movement and hopefully improve driver safety, according to The Information. Electronic logging devices (ELDs) are federally required to prevent fatigue-related accidents on trucks, but now it seems Amazon will offer its partners a custom ELD offering, possibly giving Amazon direct access to a lot more data from a tool it maintains itself.

Amazon’s Relay ELD — named after the company’s Relay platform for booking delivery jobs — works by plugging hardware into the diagnostics port of trucks to directly digest information from the engine, The Information writes. It then communicates that data over Bluetooth to be logged in an accompanying app.
