Traffic Light and Stop Sign Control
NOTE: Depending on market region, vehicle configuration, options purchased, and software
version, your vehicle may not be equipped with Traffic Light and Stop Sign Control.
Traffic Light and Stop Sign Control is designed to recognize and respond to traffic lights and
stop signs, slowing Model 3 to a stop when using Traffic-Aware cruise control or Autosteer. This
feature uses the vehicle's forward-facing cameras, in addition to GPS data, and slows the car for
all detected traffic lights, including green, blinking yellow, and off lights in addition to stop signs
and some road markings. As Model 3 approaches an intersection, the touchscreen displays a
notification indicating the intention to slow down. You must confirm that you want to continue
or Model 3 stops at the red line displayed on the touchscreen's driving visualization.
NOTE: Traffic Light and Stop Sign Control is a BETA feature and works best on roads that are
frequently driven by Tesla vehicles. Traffic Light and Stop Sign Control attempts to stop at all
traffic lights, including green lights.
WARNING: NEVER make assumptions and predict when and where Traffic Light and
Stop Sign Control will stop or continue through an intersection or road marking. From a
driver's perspective, the behavior of Traffic Light and Stop Sign Control may appear
inconsistent. Always pay attention to the roadway and be prepared to take immediate
action. It is the driver's responsibility to determine whether to stop or continue through
an intersection. Never depend on Traffic Light and Stop Sign Control to determine when
it is safe and/or appropriate to stop or continue through an intersection.
Before Using
Before using Traffic Light and Stop Sign Control, you must:
• Ensure that forward-facing cameras are unobstructed (see Cleaning Cameras and Sensors
on page 108) and calibrated (see Drive to Calibrate Cameras on page 107). Traffic Light and
Stop Sign Control depends on the ability of the cameras to detect traffic lights, stop signs,
and road markings.
• Ensure that the latest version of maps has been downloaded to Model 3. Although Traffic
Light and Stop Sign Control primarily uses visual data received from the vehicle's cameras,
greater accuracy is achieved when using the most recent map data. To check which version
of maps is currently downloaded, touch Controls > Service > Additional vehicle information.
You must connect to a Wi-Fi network to receive updated maps (see Map Updates on page
171).
• Enable the feature. With the vehicle in Park, touch Controls > Autopilot > Traffic Light and
Stop Sign Control. Once enabled, Traffic Light and Stop Sign Control operates whenever
Traffic-Aware Cruise Control or Autosteer is active.
How it Works
When Traffic Light and Stop Sign Control is enabled and you are using Autosteer or Traffic-
Aware Cruise Control, the touchscreen displays a popup message to inform you that an
upcoming traffic light, stop sign, or road marking has been detected. As it approaches the stop
location, even at an intersection where the traffic light is green, Model 3 slows down and
displays a red line to indicate where the vehicle will come to a complete stop. To continue
through the intersection—even if the traffic light is green —you must press down on the drive
stalk or briefly press the accelerator pedal to give the vehicle permission to proceed. When
you've confirmed that you want to proceed, the red stop line turns grey and Model 3 continues
through the intersection and resumes your set cruising speed.
