The correct answer is D. Wait for a safe gap
Step-by-step explanation:
A yield sign is a common road sign that includes a red inverted triangle, this sign shows drivers they are about to reach an intersection or similar and they should stop and allow other vehicles to pass (yield) until there is a safe gap or space for them to continue. Additionally, this sign is virtually universal as it can be found in roads all around the world although its name and color can vary, for example, in some countries the inverted triangle is blue or yellow and the sign is known as "give away". According to this, when you reach a yield sign, yield to cross traffic and wait for a safe gap.
