What should you do when you come to an uncontrolled intersection?

Answer: B — Stop, then proceed when safe

When approaching an uncontrolled intersection, it is important to come to a complete stop and proceed only when it is safe to do so. Option A is incorrect because driving quickly through an uncontrolled intersection can be dangerous and increases the risk of collisions. Option C is also incorrect because there are no specific rules or regulations for taking turns at uncontrolled intersections. Option D is incorrect because yielding to vehicles on the right is only applicable in certain situations, such as when approaching a roundabout. Overall, the best and safest option is to always stop and proceed with caution at an uncontrolled intersection.
