Systems, methods, and devices for detecting a vehicle's turn signal indicator status for collision avoidance during lane-switching maneuvers or otherwise. A method 700 includes detecting, at a first vehicle, a presence of a second vehicle in an adjacent lane or nearby. The method includes identifying, in an image of the second vehicle, a sub-portion containing a turn signal indicator of the second vehicle 702. The method includes processing the sub-portion of the image to determine a state of the turn signal indicator 704. The method also includes notifying a driver or performing a driving maneuver e.g. lane change, at the first vehicle, based on the state of the turn signal indicator 706. The image may be processed using a neural network which recognises turn signal regions of interest. The future movement of the second vehicle may be determined based on the turn signal status. The image may be obtained upon detecting that the second vehicle is within a collision risk zone.
