How to Track Speeding Events in Samsara
What Is the Quick Summary?
Speeding drives crash risk, fuel waste, insurance premiums, and driver turnover. Fleet managers cannot ride along with every vehicle, so they need a reliable system that detects speeding, classifies it, and routes it to the right person. Samsara – GPS Fleet Tracking Software delivers that system through configurable speeding severity levels, a dedicated Speeding Report, a Safety Inbox for review, and coaching workflows.
This guide explains how to track speeding events in Samsara from start to finish. You will learn how the platform detects speeding, how to configure thresholds, where to find events, and how to turn raw data into coaching and measurable improvement. The steps below reflect the official Samsara knowledge base, so confirm menu names against your own dashboard because features vary by license and release.
In short:
- Configure speeding thresholds at Settings > Fleet > Safety > Event Detection.
- Review flagged events in Safety > Safety Inbox.
- Analyze trends in the Speeding Report and Safety Overview.
- Coach drivers using the event evidence, then monitor score changes.
- Automate reporting and alerts so speeding never goes unnoticed.
How Does Samsara Detect Speeding Events?
Before you configure anything, understand the data behind a speeding event. Accurate tracking depends on three inputs: driver speed, vehicle location, and the posted speed limit.
Where Does Samsara Get Speed, Location, and Speed Limit Data?
According to the Samsara knowledge base, driver speed comes from ECU data when the vehicle provides it. Otherwise, the platform falls back on GPS data. During active trips, the Vehicle Gateway uploads the vehicle location to the cloud about every five seconds, and the system maps each coordinate to the closest road segment. Speed limits come from the Global Speed Limit Database, which updates quarterly. The Samsara Dash Cam does not read speed limits from road signs, so a missing limit overlay means the database has no value for that location.
| Data Input | Primary Source | Fallback or Note |
|---|---|---|
| Driver speed | ECU speed data | GPS speed when ECU data is unavailable |
| Vehicle location | Vehicle Gateway GPS, roughly every 5 seconds | Mapped to the nearest road segment |
| Posted speed limit | Global Speed Limit Database, updated quarterly | Editable through the Map Editor or speed limit overrides |
What Counts as a Speeding Event?
Samsara measures severity by two factors: how far over the limit the driver travels and how long the driver stays there. The duration ends when the driver returns to or drops below the limit. A speeding instance that exceeds your configured threshold becomes a speeding event, affects the safety score, and appears in the Speeding Trends report. Time spent over the limit that does not reach a threshold still accumulates in its severity level and still influences the driver safety score. For example, a driver who travels 6 mph over for 30 seconds adds moderate speeding time but does not trigger a speeding event under the default settings.
How Do You Configure Speeding Settings in Samsara?
Defaults give you a starting point, but your operation deserves tuned thresholds. A delivery van in a city and a long-haul truck on an interstate face different risks.
What Are the Default Speeding Severity Levels?
Samsara ships with four severity levels. The knowledge base lists these defaults for US fleets.
| Severity | Speed Over the Limit (US) | Minimum Duration |
|---|---|---|
| Light | Under 6 mph | 60 seconds |
| Moderate | 6 to 10 mph | 60 seconds |
| Heavy | 11 to 15 mph | 60 seconds |
| Severe | More than 15 mph | 20 seconds |
Non-US fleets use percentages instead. Light covers under 11 percent over the limit, moderate covers 11 to 20 percent, heavy covers 21 to 30 percent, and severe covers anything above 30 percent. Duration rules mirror the US defaults.
How Do You Change the Thresholds?
Follow these steps to customize severity levels:
- Select the Settings icon at the bottom of the Fleet menu.
- Choose Safety > Event Detection.
- Open the Speeding settings.
- Adjust Over Limit for each severity level. Pick either a percentage over the limit or a fixed difference in mph or km/h, and keep the levels sequential without overlap.
- Set the Duration, which has a minimum of 60 seconds in the configurable settings.
- Turn on Send to Safety Inbox for each category you want to review manually.
These definitions power more than the reports. Samsara uses them to build Speeding Reports, calculate safety scores, highlight trends in the Safety Overview, and trigger safety alerts. Therefore, change them deliberately and document the reason.
What Is Max Speed, and When Should You Use It?
Max Speed adds a second layer of detection. Instead of measuring against the posted limit, it flags any vehicle that exceeds an absolute speed you define for a set duration. Companies use it to enforce internal policies, such as a hard cap for heavy trucks or governed vehicles. Configure it in the same Event Detection area, set the threshold and duration, and choose whether to send events to the Safety Inbox or route them straight to the coaching queue. Samsara notes that Max Speed events affect safety scores only when they occur on or after October 8, 2024, so older events will not change historical scores.
How Do You Review Speeding Events in the Safety Inbox?
The Safety Inbox turns detection into action. It collects events that need a human decision and gives you the context to make it.
Which Speeding Event Types Appear in the Inbox?
The knowledge base describes three types:
- Max Speed: The vehicle exceeds your defined maximum speed for a continuous duration.
- Severe Speeding: The vehicle exceeds the posted limit by the configured amount for the configured duration.
- Speeding (Manual): A reviewer applied a speeding label to an event.
What Is the Review Workflow?
- Open Safety > Safety Inbox > Needs Review.
- Use the Event Type filter to select the speeding categories you want.
- Apply extra filters, such as driver, vehicle, tag, or date, to narrow the list.
- Open an event and study the evidence.
- Decide the next step: dismiss it, label it, or send it to coaching.
Inside each event, you can hover over the speed graph to see the vehicle speed, the posted limit, and the amount over. Color coding shows severity at a glance. You can also open the Trip Speeding Summary to see total time spent speeding, the number of violations, and the severity breakdown for the entire trip. If something looks wrong, open the location in Google Street View, or edit the posted limit through the Map Editor when the database is outdated or incorrect.
How Do You Analyze Speeding Trends With Reports?
Individual events show what happened. Reports show what keeps happening, and that distinction drives real behavior change.
What Does the Speeding Report Show?
According to the knowledge base, the Speeding Report highlights speeding behavior across the organization and supports coaching and safety monitoring. Reports can cover periods of up to one year, and the default view displays the last 30 days. Only speeding incidents that exceed your thresholds count as speeding events, and the report lists only drivers who drove during the selected range. Open it from your Safety Overview, then switch between Drivers and Vehicles to change the scope.
| Report Field | What It Tells You |
|---|---|
| Safety score change | How a driver’s score moved during the period |
| Hours driven | Total driving time in the range |
| Percent over speed limit | Share of driving time spent speeding |
| Severity | Time distribution across light, moderate, heavy, and severe |
| Manual speeding events | Manually entered events, shown per 1,000 miles |
Which Other Reports Help?
Several related views add depth. The Driver Speeding Report, Trip Speeding Summary, and Event Resolution Report all use speeding data. Drivers can also check their own history in the Driver Portal, where the Speeding Events tab lists every detected event. Because drivers see the same data you see, coaching conversations start from shared facts instead of arguments.
How Do You Coach Drivers and Alert Your Team?
Tracking without follow-up changes nothing. Samsara connects detection to coaching and notifications so you can close the loop.
How Do You Use the Coaching Workflow?
From the Safety Inbox, route an event for manager-led or self-coaching and update its coaching status as the work progresses. You can also send certain categories automatically to the coaching queue to save review time. Focus on the severe and heavy categories first, because they carry the highest risk, and then expand to patterns of moderate speeding.
How Do You Give Drivers Real-Time Feedback?
The platform supports in-cab voice coaching, so drivers hear a warning while the behavior is happening. Configure those alerts in the speeding settings, and pair them with the post-event coaching described above. Real-time prompts reduce the number of events, and later coaching addresses the habits behind them.
How Do You Automate Alerts and Exports?
Create safety alerts that use your severity definitions so the right people receive notifications for serious speeding. In addition, schedule safety reports for recurring delivery. Samsara’s exported driver safety reports include columns for time over the speed limit by severity, speeding event counts by severity, and manual speeding counts. Developers can also consume speeding data through the Samsara API, which provides a speeding event schema with fields such as severity level, posted speed limit, and maximum speed over the limit.
What Best Practices Improve Speeding Reduction?
Strong programs combine good settings with consistent habits. Apply these practices to get lasting results.
- Start with defaults, then tune. Review one month of data before you tighten thresholds.
- Fix bad speed limits quickly. Edit incorrect limits so drivers trust the data.
- Coach early and often. Short, timely conversations beat quarterly reviews.
- Reward improvement. Recognize drivers whose scores rise, not only those with perfect records.
- Review trends monthly. Compare tags, depots, and vehicle types to find hot spots.
- Communicate the policy. Explain what Samsara measures and why before you enforce anything.
What Are the Key Conclusions?
Tracking speeding events works best as a repeatable cycle: detect, review, coach, and measure. Samsara – GPS Fleet Tracking Software supports every stage. Configurable severity levels define what matters to your fleet, the Safety Inbox puts evidence in front of reviewers, the Speeding Report reveals trends, and coaching tools turn insight into behavior change.
To begin, open Event Detection and review your current thresholds. Next, work through a week of events in the Safety Inbox, and then schedule a monthly report for your leadership team. As your program matures, add Max Speed rules, in-cab coaching, and API integrations. Small, consistent steps produce fewer incidents, lower costs, and a safer road for everyone.

Frequently Asked Questions
Yes. You can change the speed difference and the minimum duration for each severity level in Safety > Event Detection. You can also use either a percentage over the limit or a fixed mph or km/h difference. Keep the levels sequential and avoid overlaps.
Samsara draws speed limits from the Global Speed Limit Database, which updates quarterly. If a limit looks wrong, edit it in the Map Editor from the event details, or use the speed limit override options to fix discrepancies.
Not exactly. Time spent over the limit accumulates by severity and influences the score, even when it does not reach the threshold for a speeding event. Events that exceed the thresholds count as speeding events and also affect the score. You can adjust how duration factors into scoring in the Speeding settings.
