Special lanes — Washington Permit Test
Special lanes on the Washington permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
HOV lanes are reserved for carpools, vanpools, and buses, and a vehicle must meet the occupancy requirement posted on the signs to use one.
The lane only moves faster because fewer vehicles are allowed in it.
HOV lanes are reserved for carpools, vanpools, and buses.
Motorcycles are allowed to use HOV lanes.
A motorcycle takes one person off the road in a car's place, which is what the lane is for.
Motorcycles are also allowed to use HOV lanes.
Over a reversible lane a green arrow means the lane may be used and a red X means it may not.
The lane runs the other way at other times of day, so the overhead sign is the only thing that says which.
A green arrow means you can use the lane, and, a red X means you can’t.
A steady yellow X over a reversible lane means the lane is changing direction, and a driver moves out of it as soon as it is safe.
The lane is about to fill with traffic coming the other way, and the warning is short.
A steady yellow X means the lane is changing direction, and you should move out of the lane as soon as it’s safe.
Express toll lanes and high occupancy toll lanes are free for buses, vanpools, carpools, and motorcycles, and an individual driver may pay the toll to use them.
It is the one lane where the rule is money rather than occupancy, which is why the sign matters.
Express toll lanes and high occupancy toll lanes provide toll-free express trips for buses, vanpools, carpools, and motorcycles, but they also give individual drivers the option to pay the toll to use the lanes for a faster trip.
On the test
Who may use an HOV lane in Washington?
Carpools, vanpools, and buses meeting the posted number. The lane only moves faster because fewer vehicles are allowed in it. Washington State Driver Guide, p.134: “HOV lanes are reserved for carpools, vanpools, and buses.”
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.
