The traffic light control system in Tesla cars uses front-facing cameras and a GPS to recognize traffic signs, intersection points, and road markings.
Tesla Model 3 does not show traffic lights because of obstructed cameras, non-updated maps, software issues, the wrong angle between the traffic signs and cameras, weather conditions, and bright sunlight. It also happens when driving in hilly areas, toll booths, and temporary construction signs.
It becomes difficult to drive the car for distracted drivers when the traffic light control system stops working in their vehicle.
Tesla cars use the front cameras with GPS data to show all the traffic signs and stop signals.
These cameras also detect road markings and slow the speed of your vehicle during driving. The obstructed cameras cause an issue in the detection of these markings.
The camera often cannot identify these markings of stop signals while driving on the road. The issue comes when trees, large objects, and other heavy-duty automobiles obstruct the view.
The camera cannot detect the real things because of the blockage issues. Moreover, you can also see the blur effect on the screen and cannot recognize the objects.
The dirt and dust on the front-facing cameras are also problematic and worsen the situation. You should drive carefully when the system cannot detect stop signs and intersection points.
You should need more care and attention while moving at intersection points.
Maps not updated
The traffic light also takes data from the global positioning system of your car. This is because the changing of the roads and streets is an everchanging process.
The signal often does not detect the new roads because of non-updated maps. Therefore, traffic light control performs best on the roads on which you frequently drive Tesla vehicles.
It is challenging for the system to recognize the unknown and new roads. Therefore, it cannot slow the speed after seeing the stop signal and intersection points.
You should drive actively on the new roads because of no signals from the traffic control system. It is also necessary to update the map to add new and familiar places for easy detection and safe driving.
The software and onboard computer system are essential to run this system efficiently. The software always needs to be updated to decrease the chances of error and increase efficiency.
The updated software sometimes does not recognize the ongoing system, and you have to reset its settings.
The latest version cannot work well with the already present data on the map. The bug in the system also causes software problems.
Moreover, the poorly calibrated and damaged cameras also cause this issue in Tesla Model 3.
You cannot receive any data on the screen when you do not update them for a longer time. Therefore, you should update the system simultaneously after receiving a new update notification.
Wrong angle between traffic signs and the camera
The traffic signs and angles are often presented at the incorrect angle, which causes a problem in their recognition.
The stop signs are higher on some roads that the sensor cannot see or detect suddenly while driving.
In addition, you can also see the faded image on the touchscreen because of the poor angle and incorrect identification.
The aftermarket addition of large tires increases the height of the cars and disturbs the angle between the camera and stop signs.
The weather conditions interrupt the working of the sensors and front-facing cameras. For example, most people complain that traffic light control cannot function in heavy rain.
Driving in heavy rain obstructs the view, and the small devices on the front side cannot detect different things.
In addition, the same comes in foggy weather when visibility is already low. The traffic signs are not visible due to heavy fog and zero visibility.
In addition, the ice layer on these sensors during winter days is also problematic. Therefore, you should not rely on their functioning while driving in heavy rain and foggy weather.
Spray the camera’s glass lens with water-repellent sprays to protect them from water droplets and moisture.
The bright sunlight and extreme lighting condition on the roads also decrease the efficiency of the traffic light control system.
The movement in the opposite direction causes direct sunlight to the front side of the Tesla cars.
The high beam of light from the sun causes the wrong identification of objects. Moreover, the sensors do not identify the objects because sunlight blurs their view.
Temporary signs on the construction area
The constructed areas also contain temporary signs that show that you should slow the speed of your car.
These signs show the construction area and indicate that you should move slowly to get rid of any problems.
Many people complain that the traffic control system does not recognize the temporary signs present in the construction areas.
The system cannot identify them because these roads are not frequently used. In addition, it is in the limitation of this system that it cannot identify the temporary construction area signs.
You should keenly drive your Tesla cars near these construction areas to reduce the chances of accidents.
Driving in hilly areas
Many people love to drive in hilly areas because it is an adventurous and fun experience. Expert drivers can drive better on these roads because of random turning points and deep curves.
Sometimes, the traffic control system cannot identify the traffic signs on these curves and deep roads.
You must manually stop your car in this condition and drive consciously to decrease accidents. The cameras cannot detect the upcoming stop signs due to sharp curves and steep roads in the hilly areas.
You should not move on these challenging roads at high speed because it is dangerous for your life and vehicle.
Limit the speed so the camera can easily detect the traffic signs and slows your speed accordingly.
The toll booths, also known as the tollways, are the enclosure path used to collect tolls from passing cars.
You have to slow the speed of your Tesla vehicle while passing from the toll booths for identification and payment purposes.
Many people forget to do so and must pay heavy fines for not following the rules. The traffic control system does not work at the toll booths, and you must manually slow your speed.
It is better that you should not rely on this control system while passing from the tollways. This is because the system does not show notifications on the screen and causes a problem for you.
