Entering a highway — New Hampshire Permit Test
Entering a highway on the New Hampshire permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver should use the acceleration lane to reach the speed of other vehicles before pulling onto the roadway.
Joining a highway slowly forces everybody else to brake for you, which is how a merge turns into a collision.
Use the acceleration lane to reach the speed of other vehicles before pulling onto the roadway.
A driver entering a multi-lane highway should identify a gap in traffic and merge with the traffic flow.
Merging is fitting into a gap that already exists rather than making one, which is the whole difference.

On the test
What is the acceleration lane for?
Reaching the speed of other vehicles before merging. Joining a highway slowly forces everybody else to brake for you, which is how a merge turns into a collision. New Hampshire Driver's Manual, p.16: “Use the acceleration lane to reach the speed of other vehicles before pulling onto the roadway.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
