Speeding accounts for almost a third of all traffic accidents and is a leading indicator of poor driving behavior. As such, it is one of the main contributors to the Samsara Safety Score. Here are a few common questions that address how Samsara factors speeding into the Safety Score.
Q: Is there a grace threshold of speeding over the speed limit? In other words, if I’m going 31 in a 30, does that count as speeding?
A: There is a buffer of up to 5 mph (or 8km/h) over any posted speed limit before Samsara considers a vehicle speeding. That means that drivers can drive up to 65 mph on a 60 mph road before being marked as speeding. Any time spent at or over that threshold (for example, 65 mph and over) will then be calculated into their safety score.
Q: Is there a grace period for the time spent over the speed limit? In other words, do you start counting speeding immediately after I cross a threshold?
A: Beyond the 5 mph buffer in calculating speeding, there is no grace period after crossing the speed limit before Samsara counts time spent over the speed limit.
Q: Can I be alerted when my drivers are speeding?
A: Yes. You can set alerts against posted speed limits or specified thresholds from the alerts page. To learn more, you can read about Speed Alerts here.
Driver A is driving 67 mph on a road with a speed limit of 65 mph for 5 minutes.
This will not calculate any time spent over the speed limit.
Driver B is driving 68 mph on a road with a speed limit of 65 mph. The driver then goes 70 mph for a minute and then goes back to 68 mph.
This will be calculated as 1 minute of time spent over the speed limit.
