The verdict

Proterra Powered 1 runs at 38% of its industry's injury rate - far safer than the typical Automotive harness and ignition sets manufacturing workplace, earning a grade A.

Proterra Powered 1: 2.0 TCR = 38% of Automotive harness and ignition sets manufacturing BLS 5.4 · 2y Form 300A (see methodology below)

Proterra Powered 1 safety composite

Proterra Powered 1 scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 22%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
