Yellow center lines — New Mexico Permit Test
Yellow center lines on the New Mexico permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Lines separating traffic moving in opposite directions are yellow.
Yellow tells you the traffic on the other side is coming toward you, so crossing it is risky.
Lines separating traffic moving in opposite directions are yellow.
A dashed yellow line between opposing lanes means you may cross it to pass if it is safe.
The gaps show you can see far enough ahead to pass, but you still must check for oncoming cars.
A dashed yellow line between opposing lanes of traffic means that you may cross it to pass if it safe to do so.
Where there is a solid and a dashed yellow line, you may not pass if the solid yellow line is on your side.
The solid line is on your side because your view ahead is too short to pass safely.
Where there is both a solid and a dashed yellow line between opposing lanes of traffic, you may not pass if the solid yellow line is on your side.
Two solid yellow lines between lanes mean neither side can pass.
Double lines mark a stretch where drivers going both ways lack a safe view for passing.
Two solid yellow lines between lanes of traffic means neither side can pass.
You may cross a solid yellow line to turn into a driveway if it is safe.
The line bans passing, not turning, so you can still reach a home or store across the road.
You may cross a solid yellow line to turn into a drive way if it safe to do so.
On the test
What do yellow lines on the road separate?
Traffic going opposite directions. Yellow tells you the traffic on the other side is coming toward you, so crossing it is risky. New Mexico Driver Manual, p.8: “Lines separating traffic moving in opposite directions are yellow.”
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.
