An anti-trapping method and a corresponding apparatus for a vehicle door that can be adjusted between an open position and a closed position along an adjustment path by an adjustment motor. First, a proximity sensor is used to monitor an adjustment path region ahead of the vehicle door for the presence of an obstacle during a closing movement of the vehicle door. The closing movement is stopped or reversed when an obstacle is identified in the adjustment path region. Second, when the obstacle is identified during the closing movement of the vehicle door, an additional emergency measure is taken at least when the vehicle door is already closed down to a remaining gap having size does not exceed a prespecified threshold value, and when the presence of the obstacle within this remaining gap is detected.
