Real-Time Alerts

Real-time alerts are automatic notifications that a fleet system sends the moment a predefined rule is broken: a vehicle leaves an authorised zone, an engine fault appears, a vehicle moves outside working hours or an inspection falls due. They tell the right person what happened, on which vehicle, and when, so action can follow quickly.

What counts as a real-time alert

An alert has three parts: a trigger (the event or threshold), a context (vehicle, driver, place, time) and a recipient (who must act). The trigger can come from live telematics data, such as position, ignition or a fault code, or from the fleet's records, such as a contract end date or an expiring document. Live telematics events are what make an alert truly real time; date-based reminders are scheduled warnings sent ahead of a deadline.

The main alert families

• Safety: harsh braking, sharp acceleration or speeding events that suggest risky driving, or a crash detected by the device.
• Security and usage: movement outside working hours, a vehicle entering or leaving a zone set with geofencing, an unplanned stop, a possible theft.
• Vehicle health: a diagnostic trouble code, a low battery, a warning light, a service interval reached.
• Compliance and admin: roadworthiness test, insurance, driving licence check or lease end approaching.

Setting alerts that people actually read

The risk with alerts is not having too few but too many. When every minor event triggers a message, managers stop reading them. A few rules keep the system useful:

• Start with a short list of events that always require action, then add more only if they prove useful.
• Route each alert to the person who can act on it: a site manager for zone exits, the workshop contact for fault codes, the fleet manager for expiring documents.
• Group low-priority events into a daily or weekly digest instead of instant messages.
• Review alert volumes regularly and adjust thresholds that fire too often.

This is the logic of management by exception: the team looks at what deviates from normal, not at every data point. Alerts based on location rely on real-time tracking; because they involve data about drivers, they should be explained to employees and set up in line with GDPR.

How Dadycar helps

Dadycar is a French fleet management software that brings vehicle records, telematics and car sharing together. Its alerts flag anomalies from telematics data, while reminders and due dates warn ahead of inspections, contracts and documents. Telematics works without a box on compatible connected vehicles, with an optional tracker for the others, and geofencing adds zone-based events. The AI agent Donna answers questions about the fleet in plain language, and all data is hosted in France, with OVHcloud.

FAQ

What is the difference between an alert and a reminder?
An alert reacts to an event as it happens, such as a zone exit or a fault code. A reminder is scheduled in advance for a known deadline, such as an inspection or a contract end.

How many alerts should a fleet manager receive?
As few as possible while still catching every event that needs action. If alerts are regularly ignored, thresholds or recipients need adjusting.

Do drivers need to know about alerts?
Yes. Alerts based on location or driving behaviour use personal data, so drivers should be informed of what is collected, why, and who receives the alerts.
