1. A computer-implemented method comprising:
receiving, by a hardware processor, telematics information produced by one or more sensors of a device during a trip in a vehicle, wherein the device is not electrically connected to the vehicle;
processing, by the hardware processor, the received telematics information to identify a road segment traversed by the vehicle during the trip, the road segment comprising a turn;
determining, by the hardware processor, a first point at which the vehicle begins the turn of the road segment based on one or more gyroscopic measurements included in the telematics information;
determining, by the hardware processor, a second point at which the vehicle begins braking on the road segment based on one or more acceleration measurements included in the telematics information;
determining, by the hardware processor, a probability that an advanced driver assistance system (ADAS) feature of the vehicle was operational during the trip based, at least in part, on the first point at which the vehicle begins turning on the road segment and the second point at which the vehicle begins braking on the road segment, wherein the probability that the ADAS feature of the vehicle was operational is higher when the second point precedes the first point; and
determining, by the hardware processor, a risk score for the vehicle or a driver of the vehicle based, at least in part, on the probability that the ADAS feature was operational.
