Tesla has started rolling out a software update to its newest vehicles that allows them to respond to traffic lights and stop signs.

The update Autopilot software was introduced to Tesla’s ‘early access fleet’ in late March, a select group of owners who get to test new updates before Tesla introduces to the rest of its customers. Now, the automaker has announced the software update will be introduced to Tesla vehicles equipped with ‘Hardware 3’, the latest version of the onboard computer which powers Autopilot, as well as the optional ‘Full Self-Driving Capability’ package, The Verge reports.

The system works just like you’d expect. When activated, the car will automatically slow to a stop when it recognizes a red traffic light or a stop sign. To get the vehicle to accelerate back up to speed after it stops, the driver will need to pull down once on the Autopilot stalk or tap the accelerator pedal.

Shortly after rolling out the feature to its early access fleet, Tesla stated in its release notes the system won’t work at all intersections, such as railroad crossings or pedestrian crosswalks.

“Over time, as we learn from the fleet, the feature will control more naturally,” Tesla added. “Performance may be degraded in difficult environments with pedestrians, rain, direct sunlight or when approaching traffic controls that are obstructed.”

Tesla has also stressed that users “must pay attention and be ready to take immediate action at all times, including braking,” when the system is enabled.
