Tesla Not Showing Traffic Lights (This Should Work)

Suppose you are on a road trip driving your Tesla vehicle late at night and suddenly you noticed something odd. You are not able to see the spotlight as your Tesla vehicle not showing traffic lights.

When the traffic light control system of your Tesla is not working, it becomes challenging for you to operate your vehicle. You might wonder why your Tesla vehicle does not display traffic lights. Is your Tesla facing some sort of problem?

In this article, I’ll talk about the reasons why your Tesla electric cars do not show traffic lights and their possible fixes. By the conclusion, you’ll be aware of what to do during such situations.

Let’s Get Started…!!!

How to Fix Tesla Not Showing Traffic Lights?

The traffic control system of your Tesla vehicle mainly depends upon the front-facing cameras and a GPS that detects traffic signs, intersections, and road markings.

But if your cameras are broken, you have outdated maps and software errors; Tesla cars will not display traffic lights. Moreover, it may also occur when you are driving through hilly mountains.

Here we listed some of the causes and solutions for why you are facing this issue with your Tesla vehicle:

1) Effected Cameras

Your Tesla front cameras are used to show traffic signals, road signs and also used to reduce your car’s speed while you’re driving. But it’s difficult for the hidden cameras to identify these markers. In a situation when you are driving on the road, cameras of your Tesla vehicle feel difficult to recognize these stop signal markers.

You face the problem when trees, big objects, and other large, heavy-duty vehicles block the view. The actual objects are not detected by your Tesla camera due to these hindrances. Furthermore, you are also unable to distinguish the things on your screen due to the blur effect.

Additionally, if you are traveling in sandy areas sand and dirt may affect your cameras making the matter worse and bothersome. When your Tesla system fails to recognize stop signs, it’s time for you to drive cautiously.

Follow the below stated steps to readjust your cameras and sensors to fix your Tesla’s traffic light detection:

●      From the setting menu choose the option “Service”.

●      After that you have to select “Calibrate Cameras”.

●      Follow the on-screen directions.

2) Outdated Maps

The traffic light also uses information from your car’s GPS. Streets and roads in your region are constantly changing processes. When you are driving your car at regular locations your GPS easily detects traffic signals.

But if you are going through new highways and you do not have an updated map, the GPS cannot detect traffic signals. The system has trouble identifying unfamiliar and new roads that’s why it cannot reduce its speed.

Therefore, you need to keep your maps updated.

3) Updated Software

For your Tesla vehicle system to operate effectively, software and an onboard computer system are required. To reduce any error and to boost productivity it’s important to update the software of your Tesla vehicle.

If it still fails to detect the current system, you should reset the settings of the upgraded software. You can soft reset your Tesla by pressing and holding the two scroll buttons on your steering wheel.

You have to update your Tesla system as soon as you receive an updated alert.

●      Select Controls > Software. If possible, contact Computer Update accessible to access the schedule screen.

●      Use Tesla mobile app to initiate your updating.

●      If you feel difficulty while updating the software, contact the Tesla service center.

4) Extreme Weather Conditions

If you are traveling during severe weather conditions, your Tesla camera may become obscured, making it impossible for it to recognize and display traffic lights nearby. For instance, while driving if it rains heavily outside your Tesla, the front camera won’t work properly.

The weather conditions block your Tesla vehicle cameras and sensors especially during the winter so they cannot see the traffic lights.

It’s recommended not to depend on your traffic signal feature when you are driving in extreme weather conditions. Just avoid them to protect yourself. Secondly, you can apply water-repellant sprays on your Tesla camera’s glass lens in such circumstances to shield it. 

5) Incorrect Placement of Traffic Lights

The other reason why your Tesla is showing such a problem is that sometimes the traffic signal signs are angled incorrectly, rendering them invisible to the sensors. The location of the traffic lights cannot be identified by the sensors and is shown as a blurred image.

6) Hilly Areas

It’s surely exciting and enjoyable for you to drive in hilly places. But there are many erratic turning locations and tight curves on these routes that’s why only skilled drivers can drive more safely. Similarly, the traffic management system rarely has trouble reading the traffic signs on these routes.

The narrow paths in these areas prevent your Tesla cameras from detecting traffic signs. That’s why it’s unsafe for you and your vehicle to drive at high speed on these routes.

To prevent accidents while driving from these curved and deep roadways, you must physically halt your car and drive carefully. Limit your speed so that the camera can quickly identify traffic signs and stop you down as necessary.

How Does Tesla See Traffic Lights?

As we mentioned above in detail that your Tesla vehicle identifies traffic signals by using its front-facing cameras and reacts accordingly. So, you need to know how does Tesla see traffic lights?

Let’s briefly discuss it,

●      The front-facing camera of your Tesla records images of the signal and analyzes them.

●      By using a GPS your Tesla forecast about traffic lights.

●      Then you can easily modify your speed accordingly.

●      But if you are experiencing any of the above-stated problems while driving, it’s difficult for your Tesla to recognize traffic signals.

How to Enable Tesla’s Traffic Light Notifications?

The traffic light alert system from Tesla is a fantastic safety feature.

Here’s how to activate it:

●      On your Tesla screen go to the “Controls” menu.

●      From the options select “Autopilot”.

●      Then locate and activate the “Traffic Light and Stop Sign Control” option.
