Traffic lanes — Mississippi Permit Test

Traffic lanes exist on every street or highway whether or not they are marked.

A road with no paint still has two sides, and drifting across it puts you in front of oncoming cars.

These lanes may or may not be marked, but they exist just the same.

A road's number of lanes matches the number of cars, or lines of cars, that could travel on it side by side.

Knowing how many cars fit across helps you see where the lanes are when the paint is gone.

A street or highway’s number of lanes corresponds to the number of cars (or lines of cars) that could travel on it side-by-side.

Lanes that travel in opposite directions are separated by pavement lines, barricades, or medians.

Those dividers mark where oncoming traffic begins, and crossing them by mistake can mean a head-on crash.

If lanes travel in opposite directions, they will be separated by pavement markings (lines), barricades, or medians.

Always drive in a single lane, and never change lanes unless the move can be made safely.

Straddling two lanes leaves drivers in both unsure where you are going.

Always drive in a single lane. Never change lanes unless the movement can be made safely.

Do traffic lanes exist on a road that has no lane lines?

Yes, marked or not. A road with no paint still has two sides, and drifting across it puts you in front of oncoming cars. Mississippi Driver's License Manual, p.45: “These lanes may or may not be marked, but they exist just the same.”
