Driver Behavior Monitoring That Survives Contact With Drivers
Harsh braking events mean nothing if the threshold was set for a van and applied to a loaded artic. KO Fleetz detects braking, acceleration, cornering, speeding and idling with thresholds calibrated per vehicle class, and keeps enough context on every event to survive the conversation it starts.
The driver says the number is wrong, and half the time he is right
You sit down with a driver holding a report that says eighteen harsh braking events last month. He asks which ones. You do not know. The report is a count with no incidents behind it, no locations, no times, and no way to look at any single one of them. The meeting is over before it starts and you have spent your credibility on a number you cannot defend.
Then it turns out the threshold was a default. The same deceleration figure was applied to a loaded tipper and a transit van, which means the tipper driver looks reckless for braking normally in a vehicle that weighs four times as much. His scores are terrible, his driving is fine, and everyone learns that the system does not understand the job.
The events themselves are often honest and still unfair. Somebody braked hard because a car cut in. Somebody accelerated hard to clear a junction. Counted without context, defensive driving and dangerous driving look identical, and the drivers who notice this first are the ones you least want to lose.
Events with thresholds that fit the vehicle and context that fits the road
KO Fleetz combines the tracker's accelerometer with GPS speed, which catches what neither would alone. Thresholds are set per vehicle class, because the deceleration that is unremarkable in an empty van is genuinely violent in a loaded rigid. One number across a mixed fleet produces one accurate group and several libelled ones.
Every event keeps the evidence for its own defence: time, location, speed before and after, severity, and the position in the trip. That is what makes the driver conversation possible. You are not presenting a total, you are opening the specific event at the specific roundabout, and the driver can tell you what happened there. Sometimes the answer changes the verdict.
This module detects and evidences. It does not rank people, and that separation is deliberate. Turning events into league tables, coaching and trend lines is what Driver Safety Scorecards does, on top of this data. Nor does it claim to know intent: it can see a hard stop, and it cannot see the cyclist who caused it. Anything sold as knowing why is guessing.
Capabilities
What KO Fleetz driver behavior monitoring gives your team
Harsh braking and acceleration detection
Accelerometer and GPS speed together identify rapid deceleration and acceleration, with severity graded rather than every event counted as one.
Cornering force events
Lateral force through a turn, which matters most on the vehicles you least want leaning: high-sided bodies, tankers with moving loads and anything top-heavy.
Thresholds per vehicle class
KO Fleetz gives a loaded tipper and a panel van different limits, because applying one deceleration figure across a mixed fleet manufactures offenders out of ordinary driving.
Speeding against the road limit
Compares recorded speed to the limit for the road actually being driven, rather than to a single fleet-wide number that is wrong nearly everywhere.
Excessive idling detection
Engine running while stationary beyond a threshold, split from legitimate idling such as running a tail lift, a chiller unit or a cab heater on a rest break.
Full context on every event
Time, coordinates, speed before and after, severity and trip position travel with the event, so any single one can be opened and examined.
Event pattern grouping
Groups events by driver, vehicle, route and time of day, which is how a black spot at one junction gets told apart from an actual driving problem.
Driver attribution
KO Fleetz links events to whoever was driving through the assignment or driver identification, so a shared vehicle does not spread one person's events across a shift pattern.
How it works
How KO Fleetz does it
Step 1: Calibrate thresholds to the vehicles
Set limits per class and load profile before anything is measured. Every event recorded against a default threshold is a number you will have to withdraw later.
Step 2: Run a baseline before anyone is judged
Watch the fleet for a period without consequences attached. This surfaces the junction that generates events regardless of who is driving, and there is always one.
Step 3: Open events, not totals
Take individual incidents to drivers with the location and the speed trace attached. A count invites an argument. A specific event invites an explanation.
Step 4: Feed the scorecard
Once events are trusted, they become the input for safety scoring and coaching. Ranking people on data they do not yet believe simply teaches them to resent it.

Frequently asked questions
It does not, and no telematics device does. It measures deceleration against a threshold. The physics of an emergency stop for a child in the road and an emergency stop for arriving too fast at a junction are identical. This is precisely why events carry location, speed and time, and why they are reviewed rather than automatically actioned. A system that claimed to distinguish the two would be inventing the difference.
Not one number. Set it per vehicle class, then refine it against a baseline period. A loaded articulated vehicle physically cannot decelerate the way an empty van can, so a shared threshold either exonerates the van driver or condemns the truck driver, usually both. Start from the manufacturer's braking characteristics for each class, watch what ordinary driving actually produces, and adjust from there.
No. KO Fleetz runs behaviour detection on the tracker's accelerometer and GPS, which requires no camera and no driver-facing hardware, and the behaviour data stands on its own. Where you do want the visual context — the why that motion data cannot answer — that is a separate module, Camera Intelligence, which runs computer vision over dashcam and in-cab feeds and clips the event for review. It is a genuinely bigger conversation with your drivers and your works council, so it is opt-in rather than assumed. The scorecard works with it or without it.
Through the driver assignment on the trip, or through driver identification hardware where shifts change mid-vehicle and accuracy matters. Without one of those, events belong to the vehicle rather than to a person, and pretending otherwise is how the wrong driver gets a warning. If you intend to act on individual behaviour, resolve attribution first. It is not a detail you can patch later.
No, and the distinction matters operationally. This module detects events and preserves their evidence. Driver Safety Scorecards is the layer above: it weights those events, normalises for exposure, produces a comparable score and drives coaching. You want the detection to be trusted before the ranking exists, because a league table built on thresholds drivers dispute will be rejected wholesale.
Some will, and the interesting part is that gaming it usually means braking earlier and cornering more gently, which was the objective. The failure mode to watch for is different: drivers avoiding a route that generates events, or coasting dangerously to protect a score. That happens when the number becomes the goal instead of the indicator, and it is a management problem rather than a measurement one.

Bring one loaded truck and one van, and let KO Fleetz show you why a single threshold across both was never going to hold up.
