If there is a question about right-of-way in a particular situation, what should you do?

Yielding is the correct choice because right-of-way rules are designed to ensure safety and order on the road. When you yield, you are allowing another driver, pedestrian, or cyclist the opportunity to proceed before you in situations where there might be uncertainty about who has the priority. This action helps prevent collisions and contributes to safer driving conditions for everyone.

In instances where there is confusion about right-of-way, it's always safer to give way. This is especially important at intersections, pedestrian crossings, or when merging into traffic. By yielding, you show respect for the rights of other road users, which is fundamental for maintaining a smooth flow of traffic.

The other choices could lead to unsafe situations. Speeding up can create confusion and increase the risk of accidents, while proceeding without hesitation may ignore the rights of others and lead to dangerous encounters. Using your horn might alert others, but it does not solve the problem of right-of-way and may cause further confusion or stress among drivers. Yielding is the most responsible and prudent action to take in ambiguous situations regarding right-of-way.
