Question

you are approaching this intersection. you are on the through road (going straight, represented by the vertical line on the sign). how should you proceed?
slow down and treat it like an uncontrolled intersection. after yielding to other traffic, you may go.
come to a complete stop before continuing.
continue on your way as normal, but be prepared to brake in case someone unexpectedly enters your path from a side street.

Explanation:

The road sign indicates a T - intersection where you are on the through (vertical) road. When on a through road at such an intersection, you have the right - of - way over traffic from the side street (horizontal road here), but should still be vigilant. Option 1 suggests treating it as an uncontrolled intersection and yielding, but since you're on the through road, you don't need to yield in the same way as an uncontrolled intersection for your through movement. Option 2 says to come to a complete stop, but there's no stop sign or red light, so a complete stop isn't required. Option 3: You can continue on your way as normal, but be prepared to brake in case someone from the side street (unexpectedly) enters your path, which is the correct approach as you have the right - of - way but should still be cautious of other drivers.

Answer:

C. Continue on your way as normal, but be prepared to brake in case someone unexpectedly enters your path from a side street.
