The office of defects investigation (“odi”) is opening this preliminary evaluation (pe) to assess the scope, frequency, and potential safety consequences of fsd executing driving maneuvers that constitute traffic safety violations. this investigation concerns versions of fsd that tesla has labeled as "fsd (supervised)" and "fsd (beta)." tesla characterizes fsd as an sae level 2 partial automation system requiring a fully attentive driver who is engaged in the driving task at all times. level 2 partial automation systems are designed to support and assist the driver in performing certain aspects of the driving task, requiring a driver to supervise and intervene as necessary. the driver remains fully responsible at all times for driving the vehicle, including complying with applicable traffic laws. odi’s investigation will therefore focus, in particular, on whether certain driving inputs within the control authority of fsd forestall the driver’s supervision when they are unexpectedly performed. odi has identified a number of incidents in which the inputs to the dynamic driving task commanded by fsd induced vehicle behavior that violated traffic safety laws. although reports of this nature span a variety of behaviors, the reports appear to most commonly involve two types of scenarios. the first type of scenario involves a vehicle operating with fsd proceeding into an intersection in violation of a red traffic signal. the second type of scenario involves fsd commanding a lane change into an opposing lane of traffic. with respect to the first type of scenario, odi has identified 18 complaints and 1 media report alleging that a tesla vehicle, operating at an intersection with fsd engaged, failed to remain stopped for the duration of a red traffic signal, failed to stop fully, or failed to accurately detect and display the correct traffic signal state in the vehicle interface. some complainants also alleged that fsd did not provide warnings of the system's intended behavior as the vehicle was approaching a red traffic signal. odi has identified six standing general order ("sgo") reports in which a tesla vehicle, operating with fsd engaged, approached an intersection with a red traffic signal, continued to travel into the intersection against the red light and was subsequently involved in a crash with other motor vehicles in the intersection. of these incidents, four crashes resulted in one or more reported injuries. at least some of the incidents appeared to involve fsd proceeding into the intersection after coming to a complete stop. odi's pre-investigative work, including coordination with the maryland transportation authority and state police, indicated that the problem may be repeatable, given that multiple subject incidents occurred at the same intersection in joppa, maryland. nhtsa understands that tesla has since taken action to address the issue at this intersection. with respect to the second type of scenario, odi has identified 2 sgo reports, 18 complaints, and 2 media reports alleging that a tesla vehicle, operating with fsd engaged, entered opposing lanes of travel during or following a turn, crossed double-yellow lane markings while proceeding straight, or attempted to turn onto a road in the wrong direction despite the presence of wrong-way road signs. likewise, odi has identified 4 sgo reports, 6 complaints, and 1 media report alleging that a tesla vehicle, operating with fsd engaged, proceeded straight through an intersection in a turn-only lane or executed a turn at an intersection in a through lane despite the presence of lane markings or signals. complaints also alleged that fsd did not provide warnings of the system's intended behavior. some complaints alleged that more than one of these failures occurred and, as such, the numbers are not cumulative. some of the reported incidents appeared to involve fsd executing a lane change into an opposing lane of travel with little notice to a driver or opportunity to intervene. odi’s review will a
