No. Posted Speed Limit alerts can be created only for those vehicles that are subscribed to the SpeedSafe package. However, you have the provision to add the package to a vehicle at the time of alert creation.
1. Create a Posted Speed Limit alert for a vehicle that does not have the SpeedSafe package.
(To know more about creating alerts, see the article How do I create an alert?)
2. Click Save Alert, and the application will display the following pop-up.
3. If you wish to enable the SpeedSafe package for this vehicle, tick the checkbox corresponding to the vehicle name and click on Update Alert.
