Why did I get an overspeed alert or a risk point?

An overspeed alert and a risk point are two separate things, generated by two separately-configured thresholds — so you can get one without the other. Most often, an alert fires because the account's alert threshold is set lower than the 10 km/h-or-more risk-point rule, or vice versa.

Why am I seeing an overspeed alert or a risk point?

• Your account's overspeed alert threshold is different from the risk-point threshold. These are configured separately, so an event can trigger one without the other.
• The event genuinely involved speeding. The vehicle was travelling at or above the threshold that applies to whichever one fired.
• Extra risk attributes applied to the event. A risk point (not an alert) can be affected by conditions such as the location being a school zone or open road, the time being night, or the weather — more attributes mean more points, though not a different threshold for whether a point applies at all.
• A GPS accuracy issue briefly distorted the reading. This is uncommon and usually shows up as an isolated, hard-to-explain event.

How long does a vehicle need to be over the limit before an event registers?

For a risk point, the vehicle needs to be travelling 10 km/h or more over the posted speed limit. For an overspeed alert, the threshold is whatever your account has configured for that alert — the default is 20 km/h, but it can be set higher or lower. Because these two thresholds are set independently, they won't always match on the same event. See real-time overspeed alerts for how the alert threshold is set.

What's the difference between an overspeed alert and a risk point?

A real-time overspeed alert is a notification, by app or email, sent to a chosen user as soon as a vehicle crosses the alert threshold you've configured for that asset. A risk point is a score applied to a driver's behaviour record when a vehicle travels 10 km/h or more over the posted limit, and it feeds the Driver Behaviour page, Fleet Behaviour Insights, the risk point reports, and the driver's star rating. They're configured in different places and don't depend on each other — you can have alerts with no matching risk points, or risk points with no alert having fired.

Is the posted speed limit at this location correct?

Argus checks vehicle speed against the National Speed Limit Register (NSLR), which NZTA updates on Argus on a weekly cycle, typically Sunday. If a location's posted limit looks wrong on a report, select Risk Point Query beside that point in the Risk Point Report, or see how to query or dispute a risk point.

How do I change who receives an overspeed alert?

Open Settings > Notifications, find the overspeed alert for the asset in question, and update the user it's assigned to and the email/app delivery toggles. See how to set up an overspeed alert for a driver for the full steps.

What should I do if none of these fix it?

Collect the asset ID or registration, the driver's name, and the date and time of the event, then contact Argus support so they can check the specific event.
