Traffic Light and Stop Sign Control
Stop Signs and Road Markings
When driving with Autosteer or Traffic-aware Cruise Control engaged, and Traffic Light and
Stop Sign Control enabled, Model X is designed to respond as follows when approaching
intersections controlled by stop signs, stop lines, or road markings:
Type of Intersection
No Traffic Control
Arm of T-junction
End of T-junction

Vehicle Intended Response
Model X assumes the right of way and continues straight
without slowing down or stopping.
If Model X detects a T-junction based on the map data,
Model X slows down and comes to a complete stop at the red
stop line displayed on the instrument panel. When you want to
proceed, you must take over steering and acceleration.
WARNING: Model X may not stop at a T-junction that
does not have a stop sign or stop line, or if the T-
junction is not included in the map data. Drive
attentively and be prepared to stop (when necessary
and/or appropriate).
