What should be your response as you approach a roundabout?
a. speed up.
b. choose the correct lane.
c. don't stop for traffic already in the roundabout as you have the right-of-way.
d. all of the above?

The correct answer is B) choose the correct lane. It is always important when driving to ensure you are in the correct lane, but in roundabouts, it is essential to the traffic flow. Choice A is not correct because roundabouts are designed to slow down traffic and you need to be paying attention to what is going on and slowing down before you enter. Choice C is not correct because you do not have the right-of-way; the traffic already in the roundabout does and you would need to yield to them. Choice D is not correct because choices A and C are not correct.
