If you are being closely followed and the light turns yellow as you approach an intersection, what should you do?

Answer: C — Flash your brake light

When you are being closely followed and the light turns yellow as you approach an intersection, the best course of action is to flash your brake light. This is a signal to the driver behind you that you will be slowing down. It helps communicate your intentions effectively and gives the following driver a heads-up to adjust their speed accordingly. Flashing your brake light in this situation promotes safety and reduces the risk of a rear-end collision. The other options are not the safest choices: - Speeding up to beat the light can lead to running a red light and increase the likelihood of an accident. - Stopping and waiting at the intersection when the light turns yellow might result in the following driver not expecting you to stop suddenly, potentially causing a rear-end collision. - Switching lanes quickly at the last moment can surprise other drivers and increase the risk of a collision.
