It’s not about having enough time. If you see the yellow light, and you are still far away from it, and you can stop the car by gently braking, you should stop. However, not that many people do, because they just don’t feel like it. If people don’t feel like stopping, they don’t.

If the intersection is very close when the light turns yellow, you would need to brake very hard. That’s when I just keep on going to prevent accidents. In that case, it’s not really about time either. You need to know how much distance it takes to stop your car. If you’re driving on bumpy ice, that distance will be greater than in good summer weather.
