Zego's Numbers That Make Fleet Managers Pause
Zego's recent analysis of fleet telematics and insurance claims has shone a harsh light on a problem many operators quietly accept: location data is not infallible. The data suggests a notable share of journeys include positional deviations large enough to trigger incorrect geofence events or to cast doubt on driver behaviour. In plain terms, that means legitimate drivers can end up facing penalties, disputed claims or damaged reputations because the tracking didn't match reality.
To put it bluntly, Zego highlights that accuracy varies with context - urban canyon effects near tall buildings, tunnels, poor satellite view and low-cost tracking units all influence outcomes. Evidence indicates that downtime in signal or short-lived position jumps often cluster around the busiest parts of a route, where reliable data is most needed. The upshot for fleets: what looks like objective evidence may actually be flawed, and that has financial and legal consequences.
4 Key Causes Behind GPS Inaccuracy and False Penalties
Understanding where the errors come from is the first step to handling them. Analysis reveals several recurring factors that contribute to incorrect location readings and the ripple effects they create.
- Signal obstruction in dense urban areas - Tall buildings reflect satellite signals and create multi-path errors. The result can be a jagged recorded path that jumps metres or tens of metres off the true route. Hardware and firmware limitations - Low-cost or older tracking devices often sample positions infrequently and apply naive filtering. They can record a vehicle as stationary when it was moving or vice versa. Connectivity gaps and buffering logic - When a device loses cellular connectivity it buffers data locally. The upload logic may compress that buffered data into single points, falsely marking long stops or detours. Geofence configuration and map mismatches - Poorly placed geofences, use of straight-line distances instead of road-aware boundaries, and outdated map data can all turn a valid stop into an apparent breach.
Compared with more controlled environments - rural roads with open sky - cities routinely score worse for GPS fidelity. The comparison indicates fleets operating in urban settings should not treat every alert from a tracker as dispositive proof without corroboration.
How Misplaced Coordinates Turn Into Real-World Penalties
Analysis reveals a chain of events that typically leads from a minor GPS hiccup to a serious claimed penalty. It usually starts with a raw data blip and ends with human consequences.
From blip to breach - a typical scenario
Tracker records a spurious position due to signal bounce near a high-rise. Fleet management software flags a geofence breach or a route deviation. Automated systems issue a ticket, driver alert or an insurer query. Driver disputes the alert, but the first pass investigation relies on the same flawed data source.Evidence indicates automated penalty workflows are especially vulnerable. Where companies allow systems to trigger fines or sanctions without quick human review, false positives can snowball. In one illustrative example, a driver stopped briefly beside a narrow street. The tracker recorded the stop on the wrong side of a nearby private car park. An automated penalty letter followed, leading to a week-long dispute and a late fee. The financial hit was modest, but trust was damaged.
Expert perspective - why context matters
Industry experts point out that location is just one data point. Telemetry such as speed, heading, accelerometer readings and timestamps provide context. If only position is considered, the narrative is fragile. The data suggests systems that weigh multiple signals produce far fewer false alarms. A risk manager I spoke with compared it to reading a weather report with only temperature - you miss the wind and rain.
Contrast: high-end telematics vs cheap trackers
Higher-end telematics packages generally integrate multiple sensors, apply better filtering algorithms and update more frequently. Cheap trackers tend to favour battery life and cost over sampling rate and filtering sophistication. The contrast is clear: better devices reduce the frequency of false penalties but cost more up-front. For some small operators that trade-off is acceptable; for others the extra expense is hard to justify without a quantified return on investment.
What Fleet Owners Should Understand About GPS Data Reliability
Put simply, GPS is useful but not absolute. Fleet owners need a calibrated view of what tracking data can and cannot prove. The data suggests treating telematics business van telematics as strong suggestive evidence rather than single-source proof for punitive actions.
Key takeaways from the evidence
- Reliability is situational - urban areas and complex environments raise error rates. Sampling frequency and sensor fusion matter - more data points and types reduce false positives. Configuration choices shape outcomes - poorly drawn geofences or default settings create avoidable disputes. Automated enforcement increases the stakes - without quick human review, errors become penalties.
Analysis reveals that companies which combine telematics with human oversight and clear dispute processes reduce both costs and employee friction. Evidence indicates transparency helps: when drivers can see the raw data and understand the rules, disagreements are resolved faster.

Here are concrete, measurable actions informed by the findings. The list is designed to be applied by small operators and larger fleet managers alike. Evidence indicates these steps reduce false alerts while keeping the benefits of telematics.
Audit your geofence and map settings monthlyCheck geofence boundaries against real-world roads and private property. The data suggests many false breaches are simple misplacements. A monthly audit, documented with screenshots and notes, is a small operational cost that prevents repeat disputes.
Use sensor fusion, not position-only logicIntegrate speed, heading and accelerometer data into breach logic where possible. Analysis reveals that multi-signal rules catch many spurious events: if the device reports 40 km/h and a geofence breach at the same time, it's more likely a position error than a deliberate breach.
Establish clear human review thresholdsDefine criteria where alerts require human sign-off before issuing penalties - for example, any geofence breach shorter than three minutes or any deviation under 50 metres. Evidence indicates that adding this filter prevents unnecessary enforcement and preserves managerial credibility.
Create a driver-facing dispute workflowAllow drivers to view raw trace data and raise immediate disputes with supporting info such as photos or timestamps. Studies and field reports show transparent workflows reduce escalation and speed resolution by a factor of two or three.
Invest selectively in better hardware and firmware updatesCost-benefit analysis is key. For high-value or high-risk routes, choose devices with higher sampling rates, better GNSS chips and active firmware support. Comparison tables and pilot tests are useful before rolling out at scale.
Measuring success
Track three KPIs to know if your changes are working: false alert rate (alerts overturned after review), average dispute resolution time and cost per disputed incident. Set baseline numbers before changes, then measure monthly. The data suggests modest process changes can reduce overturned alerts by 30-60% within three months.
Quick Self-Assessment for Fleet Managers
Use this short quiz to spot weaknesses in your current setup. Answer each question Yes or No.
If you answered "No" to two or more questions, the data suggests you have exposure to unnecessary disputes and potential costs. Start with the items that are cheapest to fix - configuration and review thresholds - before committing to hardware upgrades.
Closing Perspective: Balancing Trust and Evidence
GPS and telematics bring real value - safer routes, cleaner billing and better claims handling. The tricky part is acknowledging the technology's limits while still using it to improve operations. Analysis reveals that treating location data as part of a broader evidence set, rather than the sole arbiter of truth, avoids many of the harms Zego's research flags.
Comparisons between fleets that combine technology with human judgement and those that rely entirely on automated enforcement are striking. The former tend to report fewer disputed penalties, better driver morale and quicker incident resolution. Evidence indicates that the extra operational discipline - audits, thresholds and transparent disputes - pays back both financially and in team cohesion.
The practical approach is straightforward: accept that GPS will sometimes get things wrong, build checks that catch obvious errors, and give people the tools to correct mistakes when they occur. That path keeps the benefits while reducing the chances of a single misplaced coordinate becoming an expensive or reputational problem.
Next steps
If you manage a fleet, commit to a 90-day improvement plan: run a geofence audit, enable multi-sensor alerting, set human review thresholds and pilot better hardware on a handful of vehicles. The data suggests those targeted moves will cut false penalties and strengthen trust between drivers, insurers and managers.
Analysis reveals that transparency is the linchpin - make data visible and contestable, and you turn an imperfect technical record into a reliable management tool rather than a source of conflict.
