Entering a freeway — Arizona Permit Test
Entering a freeway on the Arizona permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Traffic entering a freeway must yield the right-of-way to traffic already on the freeway.
Cars on the freeway are already at speed and have little room to move over. Forcing your way on puts you in their path.
Traffic entering a freeway must yield right-of-way to traffic already on the freeway.
When entering a freeway, match the speed of your vehicle to the speed of traffic in the freeway’s right lane.
A car that joins at a crawl makes the drivers behind it on the freeway brake hard or swerve.
Match the speed of your vehicle to the speed of traffic in the right lane of the freeway.
When entering a freeway, do not cross a solid line or drive through a gore area.
Cutting across the solid line puts you into the freeway where drivers are not looking for a merging car.
Do not cross a solid line or drive through a gore area.
On the test
Who must yield when a car on the on-ramp meets traffic already on the freeway?
The car entering the freeway. Cars on the freeway are already at speed and have little room to move over. Forcing your way on puts you in their path. Arizona Driver License Manual and Customer Service Guide, p.31: “Traffic entering a freeway must yield right-of-way to traffic already on the freeway.”
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.
