You are in the right lane of an interstate, passing an on-ramp. A car on the ramp is speeding up to merge right beside you. The left lane is clear. What should you do?
A is in the interstate’s right lane beside B on the entrance lane. The lane to A’s left is clear.
Correct answer: Check your mirror and blind spot, signal, and move to the left lane
Why
Merging goes best when drivers on the main road help. On a controlled-access highway, when you see someone entering, move one lane to the left if it is clear and safe. Montana law lets you leave the right-hand lane for this, but you still must signal and make sure the lane change is safe.
