  Teleoperation is becoming an essential feature in automated vehicle concepts,
as it will help the industry overcome challenges facing automated vehicles
today. Teleoperation follows the idea to get humans back into the loop for
certain rare situations the automated vehicle cannot resolve. Teleoperation
therefore has the potential to expand the operational design domain and
increase the availability of automated vehicles. This is especially relevant
for concepts with no backup driver inside the vehicle. While teleoperation
resolves certain issues an automated vehicle will face, it introduces new
challenges in terms of safety requirements. While safety and regulatory
approval is a major research topic in the area of automated vehicles, it is
rarely discussed in the context of teleoperated road vehicles. The focus of
this paper is to systematically analyze the potential hazards of teleoperation
systems. An appropriate hazard analysis method (STPA) is chosen from literature
and applied to the system at hand. The hazard analysis is an essential part in
developing a safety concept (e.g., according to ISO26262) and thus far has not
been discussed for teleoperated road vehicles.
