How the test asks about it
- 1.
This sign warns that:
Not quiteCorrect answer: B — Traffic from another roadway will join yours and both must adjust
A merge means two streams become one. Neither driver has an automatic right-of-way; both are expected to adjust speed and position.
Many drivers believe the merging vehicle must always yield. The sign warns both roadways; cooperating beats insisting.
- 2.
You are on the main road and see this sign. What condition is ahead?
Not quiteCorrect answer: B — Another roadway joins yours ahead and the two streams continue in the same lane
A merge warning means two streams of traffic come together into one path, so a vehicle you cannot yet see may be arriving beside you. Adjusting speed and opening a gap early is what keeps the blend from becoming a conflict.
Confusing a merge with an added lane. In a merge there is no extra lane waiting, so one driver has to make room and the other has to take it.
