Driver's License Test Prep
New York Practice Lane Changes & Merging

Unless a stop or yield sign or signal controls the entrance ramp, how should you use the ramp to enter an expressway?

  1. A.
    Accelerate to expressway speed and blend with traffic Correct
  2. B.
    Match the speed of the slowest lane on the expressway
  3. C.
    Enter at the ramp's posted advisory speed and hold that pace
  4. D.
    Drive slowly so following traffic can pass you first
The Why

The answer is "Accelerate to expressway speed and blend with traffic"

The manual says the ramp is where you accelerate to expressway speed and blend with traffic when no sign controls the entry. Choice D, driving slowly so following traffic can pass first, is the habit drivers bring from pulling out of a side street onto a busy road; a ramp is built as an acceleration lane, and entering under speed forces expressway drivers to brake for you.

Why the others miss

The traps in the wrong answers

B. Match the speed of the slowest lane on the expressway

The manual asks you to blend with traffic in the lane you enter, not to hunt for the slowest one first. This answer reads the slowest lane as the safest, but the merging task is set by the right lane the ramp feeds.

C. Enter at the ramp's posted advisory speed and hold that pace

The ramp's advisory is a maximum for a curve, not a target speed to hold onto the expressway itself. This answer reads a curve advisory as a merge target because both are numbers printed on the ramp.

D. Drive slowly so following traffic can pass you first

The ramp is an acceleration lane, and easing along it forces expressway drivers to brake for the entering car. This answer carries over the yielding habit a driver uses when pulling out from a side street onto a busy road.
