I'm not sure what the source of this Google Sheet is since it is not identified anywhere on the document. I also don't know much about how telematics work, but it occurs to me after viewing the data on the Google sheet that the telematics may only report those events that an operator initiates, but not what occurs automatically. For example, in my own vehicle, my lights turn on automatically when I place the vehicle into gear and my doors automatically lock when I reach a certain speed. I don't know if my own vehicle telematics would record those events which are designed to and do occur automatically.
Applying this thinking to your example of lines 35 and 36:
It may be that sometime before 8:48 PM the truck was put into gear to "Drive" and the parking lights automatically turned ON (an automatic event that perhaps isn't recorded by telematics so isn't represented here) and then the operator manually turned the parking lights OFF at 8:48PM (an operator-initiated event that is recorded by telematics). Then, sometime before 9:25PM, the truck was again switched into "Drive" gear so that the parking lights automatically turned on again (not recorded by telematics) and the operator manually turned them off at 9:25PM (recorded by telematics).
