UK Driving Theory Practice Exam

Red and amber lights showing together indicate that you must wait for green before crossing the stop line. This means that you are not allowed to proceed through the intersection until the light turns green. Options A, B, and D are incorrect because they do not accurately describe the meaning of the red and amber lights together. Option A, "Proceed with caution," implies that you are able to continue through the intersection, but with caution. Option B, "Prepare to stop," suggests that you should be getting ready to stop, but not that you are required to wait for green. Option D, "Stop and proceed if no traffic is coming," is incorrect because it ignores the fact that the lights are programmed to regulate traffic and you must follow their instructions. Therefore, option C is the only correct answer.
