What should you do when approaching a light that has just turned yellow?

Speed up
Stop
Change lanes safely
Accelerate

The correct answer is: Stop

A Speeding up can be dangerous as the light is about to turn red. It could result in a traffic violation or even a collision if other cars have already started to stop. C: Changing lanes may not be necessary as the light may turn green before you approach it. Additionally, changing lanes can also be dangerous if other cars are also changing lanes. D: Accelerating can put you at risk of running a red light and causing an accident. It is safer to start slowing down and coming to a stop.
