But we run a 48-van mixed fleet and, after a month of flooding phones with real-time speed and following-distance alerts via Samsara, driver morale dipped even though our incident rate fell 18%. What thresholds (mph over and time-to-trigger) and coaching cadence are you using to keep risk down without alienating solid drivers?
We run about 40 vans and ended up setting in-cab speed at posted +10 mph sustained 10s, and following-distance only when headway drops <0.8s for 3s; everything else stays silent and just logs to the dashboard. Coaching is weekly 15 min only for folks with 3+ severe events in a week; everyone else gets a monthly roundup — kept morale up while incidents still fell. Your 18% drop is great, but the ‘real-time’ flood via Samsara is — try the grace period first; is your mix more urban or highway?
For our 50‑van mix, we ran a 30‑day “quiet mode” in Samsara — no phone pings except “posted +12 for 20s” or “headway <0.7s for 2s above 40 mph” — and coached only off a Friday trend report. Did your month of alerts tank morale more from the buzzing or the frequency of supervisor follow‑ups? That tweak kept the 18% drop while getting buy‑in from solid drivers.
We cap Samsara alerts to 1/hour, speed posted +15 for 15s; weekly top‑five 1:1s — no more ‘flooding phones’. Thoughts?
