Obstruction and directional markings — Hawaii Permit Test
Obstruction and directional markings on the Hawaii permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Obstruction markings guide you around things in the road such as bridge supports; you must pass only to the right of yellow obstruction markings.
A driver who goes left of a yellow marking ends up in the lanes of oncoming traffic.
You may pass to either side of white obstruction markings but you must pass only to the right of the yellow markings.
You may pass to either side of white obstruction markings.
A driver who thinks every marking must be passed on the right swerves across lanes for no reason.
You may pass to either side of white obstruction markings but you must pass only to the right of the yellow markings.
White arrows painted in a lane show the way you must go; where the arrows show more than one direction, you may choose any of them.
A driver who goes straight from a right-turn-only lane cuts across the car beside him.
Where arrows indicate more than one direction, you may choose any direction indicated.
On the test
How must you pass yellow obstruction markings in the road?
Only to the right of them. A driver who goes left of a yellow marking ends up in the lanes of oncoming traffic. State of Hawaii Driver’s Manual, p.37: “You may pass to either side of white obstruction markings but you must pass only to the right of the yellow markings.”
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.
