Texas Practice Road Markings

On a one-way road with several marked lanes, what color is the broken lane line between your lane and the next?

  1. A.
    Red
  2. B.
    Green
  3. C.
    White Correct
  4. D.
    Yellow
The Why

The answer is "White"

The manual says when each lane on a one-way road is marked with a broken white line, you may drive in any lane. Drivers land on D by carrying over the color pairing they learned first on two-way roads, where yellow separates traffic moving in opposite directions.

Why the others miss

The traps in the wrong answers

A. Red

Red is not used for lane dividers in Texas; it appears on stop signs and painted curbs. This answer files every strong warning under red because that color reads as the loudest instruction on the road.

B. Green

Green is used on guide signs for highway information, not for pavement striping between lanes. This answer borrows green from the traffic light because that is the strongest place a driver associates the color with permission to move.

D. Yellow

Yellow separates traffic moving in opposite directions; a one-way road carries no opposing traffic to divide. This answer carries the two-way road color over to a one-way road because that is the pairing new drivers learn first.
