receive a telematics data stream originating from a telematics device installed in a vehicle;
define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window comprising:
a logical window;
a first buffer preceding the logical window; and
a second buffer following the logical window;
the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows without overlapping the one or more neighboring logical windows;
identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows; and
store an indication of the vehicle event in association with at least some of the portion of the telematics data stream.
