Geotab blends NAVTEQ and OpenStreetMap posted speed data, then looks at where the vehicle was before and where it went next to identify the right road. That context helps it separate a highway from the frontage road running alongside it.

According to Geotab, posted road speed can be trusted for roughly 99% of trips. A small number of roads have missing or incorrect limits, so it’s wise to verify important exceptions before you act on them.

An exception is the record MyGeotab logs when a vehicle violates a rule, like speeding. An alert is the notification that goes out about it. You can look back through every exception in reports whenever you like, and decide which ones also notify your team.

Yes. Rule events can go out right away by email or inside the system to the people you pick. The Geotab device can also sound a beep in the vehicle so the driver hears about it immediately.

No. The in-cab threshold is a fixed speed that you set on the device. Rules that compare a vehicle’s speed to the posted limit are set up in MyGeotab.

Combining them gives you the best coverage. The in-cab beep works as a fixed ceiling, such as a company-wide maximum, and corrects drivers on the spot. Posted-speed rules in MyGeotab reveal who is exceeding the real limit and by how much.

Three tools handle most needs. Trips History marks speeding events on the trip log and the map. Speed Profile charts a vehicle’s speed against the road’s limit. The Exceptions Detail Report lists violations for any date range and exports to Excel or PDF.

Yes. Trips History shows warning-triangle markers in the rule’s color, and the vehicle’s route on the map changes color wherever the rule was broken. Speed Profile then shows how long the vehicle stayed over the limit.

Yes. You can run the Exceptions Detail Report for any time frame and export it to Excel or PDF, which works well for managers, insurers and driver reviews.

Yes. Rules can be based on how far over the posted limit a vehicle is, with a minimum speed so slow zones are ignored, plus time or distance conditions so only sustained speeding gets flagged. For instance, you could trigger only when a vehicle is more than 10 mph over the posted limit.

No. You can turn on a built-in stock rule to get going quickly, or copy it into a custom rule that fits your policy. Custom rules can be created in the plain-English rule editor or the advanced conditions editor.

Usually the threshold is set too low, or the rule catches very short spikes. Raising the margin over the posted limit and adding a time or distance condition, such as driving above a set speed for more than a minute, keeps your report focused on clear or dangerous violations.

Editing an existing rule clears its historic events, since they may not be valid under the new settings. You can reprocess a reasonable date range to bring them back, and large requests are typically handled after hours. Check with us before changing a rule you depend on for reporting.

Yes. Besides email and in-system notifications, rule events can be pulled into your own tools through the MyGeotab Data Feed API.

Yes. Exception reports and Speed Profile give you specific events to go over with a driver, and in-cab alerts provide feedback without a manager involved. Since a small portion of posted speed data can be missing or wrong, confirm any exception that might lead to discipline before acting on it.

Speeding is one of several behaviors that raise collision risk, along with harsh braking, hard acceleration and sharp cornering. The Safety Center combines these in risk analytics and lets you compare your fleet with similar fleets. Begin with the speeding tools, then use the Safety Center for the bigger picture and to prioritize coaching.

Yes. We can help you pick a sensible starting rule, adjust it after the first few weeks of data, and guide you through rule changes so you don’t accidentally lose reporting history. Contact us to get started.
