To help you maintain full visibility and protect product quality during transit, our system monitors trailer data throughout each route. When certain conditions are not met, a violation is triggered. Below is a clear breakdown of the different types of violations, what causes them, and what sets off each one.
Route violations can be viewed in two ways:
By clicking on the red warning icon in the following location within a specific route:

Violation Types
There are four types of violations (Excessive Gap in Data, No Data, Hot, Cold). The following sections explain each of them:
1. Excessive Gap in Data Violation
An Excessive Gap in Data Violation occurs when a trailer is actively running a route but stops transmitting data to the system for a specific period of time.
What Triggers It?
No data is reported for longer than the time threshold set by your DC.
The standard threshold is typically 40 minutes, but this may vary depending on DC configuration.
Common Causes:
Trailer device temporarily losing signal.
Power or antenna issues.
Telematics device malfunction.
Connectivity interruptions.
Even if the trailer resumes reporting later, the violation is triggered once the reporting gap exceeds the configured time limit.
If you would like to understand why the trailer stopped reporting data during the route, we recommend contacting your telematics provider for further investigation and clarification regarding the cause of the violation.
2. No Data Violation
A No Data Violation is more severe than a data gap. It happens when no data is received from the trailer during the entire duration of the route.
What Triggers It?
Zero data points are transmitted from route start to route end.
Common Causes:
Trailer was not properly linked to the route.
Device was completely offline.
Hardware failure.
Incorrect serial number assignment.
This violation indicates a complete absence of visibility for that route.
If you would like to understand why the trailer did not report any data during the route, we recommend contacting your telematics provider for further investigation and clarification on the cause of the violation.
3. Hot Violation
A Hot Violation occurs when the trailer’s internal temperature rises above the allowed maximum threshold.
What Triggers It?
Temperature readings exceed the configured upper limit for the route or commodity.
Common Causes:
Reefer unit malfunction.
Door left open for extended periods.
Improper temperature settings.
External environmental conditions.
Hot violations are critical for temperature-sensitive goods such as produce, dairy, frozen items, or pharmaceuticals.
4. Cold Violation
A Cold Violation occurs when the trailer’s temperature drops below the allowed minimum threshold.
What Triggers It?
Temperature readings fall below the configured lower limit.
Common Causes:
Reefer unit overcooling.
Incorrect temperature set point.
Sensor calibration issues.
Cold violations can be just as damaging as hot violations, especially for fresh produce that can freeze and become unsellable.
Temporary Violations Due to Data Delays
In some cases, a violation may be triggered due to a temporary delay in receiving data from the trailer.
Example: Telematics Provider Outage
If a telematics provider experiences an outage or other communication issue that delays data transmission, our system will not have access to the most current route data. As a result, the system may trigger an Excessive Gap in Data Violation or a No Data Violation because it appears that the trailer has stopped reporting.
Once the telematics outage is resolved and the trailer begins reporting data again, the delayed data will be transmitted to our system. After all missing data has been received and processed, the system will automatically recalculate the route conditions using the complete dataset.
If the recalculation shows that the violation was caused solely by the delayed data transmission, the violation will be automatically removed.
Why This Happens
Our system continuously analyzes incoming trailer data to calculate product temperatures and detect potential issues in real time. When data transmission is delayed, the system may not have enough information to accurately determine route conditions at that moment.
To ensure potential issues are not missed, the system may temporarily trigger a violation based on the available data.
What Happens Next
Once the delayed data is received, the system automatically recalculates route conditions using the complete dataset.
If the newly received data shows that route temperatures remained within the acceptable range, the violation will be automatically removed and no RCA will be generated.
As a result, customers may occasionally receive a violation notification that later disappears after the missing trailer data is received and processed. This behavior helps ensure that potential issues are identified promptly while still allowing the system to correct violations when complete data becomes available.
