Every enabled rule produces a score: 100 = perfect, 0 = worst possible. The formula depends on what the rule measures:

Each rule score is multiplied by its weight (the % you set), then the totals are summed and divided by 100:

Weights must total exactly 100%. You control which behaviours matter most — e.g. assign 35% to Speeding if that is your fleet's biggest concern.

Distance source: Total km is taken from Geotab Trip records for the selected period, not from exception event distances. Exception distances (how far the vehicle travelled during a violation) are used only as numerators in the Speeding and Seat Belt formulas.

Geotab records when each violation happened and which vehicle caused it — but the violation by itself doesn't include a location. So to put it on the map, FleetLume By EnVue looks up where that vehicle was at the exact moment of the violation, using the vehicle's GPS trail, and drops a pin there.

Repeat that for every violation in your selected period, and the pins build up into the heat map you see — the more violations in one spot, the brighter and bigger the blob.

Each coloured blob marks a location where violations happened. The bigger and brighter the blob, the more violations occurred there. Every blob matches the colour of the rule that caused it — so you can instantly tell whether an area has a speeding problem, a harsh braking problem, or something else.

Think of it like a weather heat map — the "hottest" spots are where your drivers are triggering the most alerts.

A Danger Zone is a specific location where violations keep repeating. FleetLume By EnVue automatically groups nearby events and ranks the worst spots. The top 10 are listed in the sidebar on the right.

This page answers “where do violations happen most?”, so it plots every violation it can match to a GPS location. A portion can't be matched — for example a vehicle with sparse GPS logging, or an unusually busy stretch — so the map is a representative picture of your hotspots, not a one-to-one count of every single event.

For finding problem areas, that's exactly what you want and the hotspots are reliable. If you need an exact violation count, use the Driver Safety Scorecard or Geotab's own reports — those tally every event.
