Reversible lanes — Delaware Permit Test
Reversible lanes on the Delaware permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Reversible lanes, which carry traffic one way at some times and the other way at others, are usually marked by double broken yellow lines.
A driver who misses the markings can end up facing rush-hour traffic head-on.
These lanes are usually marked by double-broken yellow lines.
Over a reversible lane, a green arrow means you can use the lane beneath it, and a red "X" means you cannot.
A driver who enters under a red X is driving straight at traffic that owns the lane.
A green arrow means you can use the lane beneath it; a red “X” means you cannot.
Over a reversible lane, a steady yellow "X" means the use of the lane is changing and you should move out of it as soon as it is safe.
A driver who stays in the lane after the yellow X will soon meet cars coming the other way.
A steady yellow “X” means that the use of the lane is changing and you should move out of it as soon as it is safe to do so.
On the test
How are reversible lanes usually marked?
Double broken yellow lines. A driver who misses the markings can end up facing rush-hour traffic head-on. Delaware Driver Manual, p.85: “These lanes are usually marked by double-broken yellow lines.”
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.
