DGT Intersections & Right-of-Way Flashcards

At a T-intersection where no signs or signals are present, who must yield?

Answer: The driver on the terminating road must yield to traffic on the through road

At a T-intersection, vehicles on the road that ends (the stem of the T) must yield to vehicles on the through road.

When entering a roundabout, who has the right-of-way?

Answer: Vehicles already circulating inside the roundabout

Vehicles already in the roundabout have the right-of-way; entering drivers must yield until there is a safe gap to merge.

What should a driver do when approaching an intersection and the traffic light changes from green to yellow?

Answer: Stop if it is safe to do so before the stop line

A yellow light signals that the light is about to turn red; drivers should stop if they can do so safely before the stop line.

Which vehicle has the right-of-way at an intersection where one road has a stop sign and the other does not?

Answer: The vehicle on the road without the stop sign

The stop sign requires drivers to yield to all traffic on the intersecting through road before proceeding.

What does it mean to 'take turns' or 'alternate' at a zipper merge on a lane closure?

Answer: Drivers in both lanes take turns merging one-for-one at the merge point

A zipper merge means both lanes remain in use until the closure point, then vehicles alternate one-for-one, improving traffic flow and safety.

When two vehicles meet on a narrow mountain road where neither can pass, which vehicle has the right-of-way?

Answer: The vehicle traveling uphill

The vehicle traveling uphill generally has the right-of-way because it is more difficult to reverse downhill and maintain vehicle control.
