Lane center barrier lines — Mississippi Permit Test
Lane center barrier lines on the Mississippi permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A broken yellow line separates traffic lanes that move in opposite directions.
If you think a yellow line splits lanes going your way, you may drift into a car coming at you.
A broken yellow line separates traffic lanes that move in the opposite directions.
You may cross a broken yellow line into the oncoming lane only to pass, and only when it is safe to pass.
The far lane is for cars coming toward you, so you may be in it only as long as a safe pass takes.
Crossing into the oncoming lane is permissible ONLY for passing and only when it is safe to pass.
A broken white line means travel in the same direction is permitted on both sides of the line.
Knowing that cars beside you go your way helps you judge when a lane change is safe.
A broken white line means travel in the same direction is permitted on both sides of the line.
A vehicle may cross a broken white line to change lanes when it is safe to do so.
A lane change across a dashed line is fine, but a car in your blind spot makes it a crash.
A vehicle may cross the line to change lanes when it is safe to do so.
Where a broken yellow line runs beside a solid yellow line, you may pass with caution if the broken line is closest to your lane; if the solid line is closest, passing is forbidden.
The solid line is on the side where the view ahead is too short to pass safely.
If the broken line is closest to your lane, you may pass with caution. If the solid line is closest to your lane, passing is forbidden.
A single solid white line keeps traffic going the same way on both sides, and crossing it is discouraged.
A solid line often marks a spot where lane changes are risky, such as near a turn or an exit.
A single, solid white line means travel in the same direction is permitted on both sides of the line. Crossing a single white line is discouraged.
Passing from either side of a double solid yellow line is prohibited.
Two solid yellow lines mean the road ahead is too risky to pass from either way.
Passing from either side of a double yellow line is PROHIBITED.
Crossing a double solid white line is prohibited.
Two white lines wall off a lane for a reason, and a car that cuts across them surprises the lane it enters.
Crossing a double white line is PROHIBITED.
On the test
What does a broken yellow line on the road separate?
Lanes moving in opposite directions. If you think a yellow line splits lanes going your way, you may drift into a car coming at you. Mississippi Driver's License Manual, p.25: “A broken yellow line separates traffic lanes that move in the opposite directions.”
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.
