Most GPS trackers can tell you how fast a vehicle is moving, and many also let you create a fixed alert such as “Alert me if the vehicle exceeds 80 mph.” That is useful, but it does not always tell the full story.
A fixed speed alert tells you how fast the vehicle is going, but not whether that speed makes sense for the road.
Real-Time Speed vs Posted Speed
Real-time speed tells you how fast the vehicle is actually traveling. Posted speed tells you the speed limit for the road where the vehicle is driving. Looking at both together gives you a clearer picture of what is actually happening.
For example, instead of simply seeing that your vehicle is traveling at 72 mph, you can understand that the posted speed is 55 mph and the vehicle is traveling 17 mph over the limit. A regular GPS tracker may only give you the vehicle speed, while a more advanced telematics platform can provide the road context as well.
Why Fixed Speed Alerts Aren’t Always Enough
Traditional speed alerts are usually based on one fixed number. For example, you may choose to receive an alert whenever the vehicle exceeds 80 mph.
The problem is that a fixed threshold does not take the road into account. Driving 68 mph in a 70 mph zone is very different from driving 68 mph in a 35 mph zone. A basic speed alert may not distinguish between those situations, while posted-speed monitoring can.
For Turo hosts, that difference matters because the goal is not simply to know that the vehicle was moving fast. The goal is to understand whether it was being driven significantly above the limit for that road.
Why Posted Speed Matters for Turo Hosts
Posted speed gives hosts a much more useful way to interpret driving behavior. If a vehicle reaches 90 mph, the number alone does not tell the whole story. Ninety miles per hour in a 70 mph zone is 20 mph over the limit, while 90 mph in a 40 mph zone is 50 mph over.
In Florida, driving 50 mph or more above the posted speed limit can qualify as dangerous excessive speeding. Florida law also covers certain cases involving speeds of 100 mph or more, and a first conviction may carry up to 30 days in jail, a $500 fine, or both.
That is a strong example of why posted speed is not just another data point. The context of the road can completely change how serious a speeding event is.
Turn Posted Speed Into Actionable Alerts
This is where modern GPS tracking becomes more useful than simply displaying another number.
Sonar Telematics allows Turo hosts to configure a Posted Speed Exceeded threshold based on how far above the road’s speed limit they want to be alerted. For example, you could configure the threshold at 20 mph over the posted speed limit.
Because the threshold is based on the road’s posted speed, it adapts to where the vehicle is actually driving rather than relying only on one universal maximum speed.
You can also choose to receive these alerts through push notifications, email, or both, helping you stay informed without constantly watching every vehicle on a map.
Review Posted Speed Exceeded History
The value does not stop with the live alert. Sonar Telematics can also provide a history of posted-speed events, allowing you to go back and review when and where a vehicle exceeded the road’s speed limit.
That means you are not just seeing one notification in the moment. You can review the event later and understand the vehicle speed, the posted speed, the difference between the two, and where the event occurred.
For Turo hosts managing multiple vehicles, that historical context makes it easier to review meaningful speeding events without constantly monitoring every trip in real time.
See More Than Just Speed
