Quick Scoop: Direct Answer

For the question “which line is used to mark the right edge of a road” the correct answer is:

This solid white edge line separates the travel lane from the shoulder and helps drivers see where the pavement ends, especially at night or in bad weather.

Why it’s a solid white line

  • Right edge lines are specifically defined in road rules as solid white lines marking the right-hand edge of the roadway.
  • Left edge lines, by contrast, are typically solid yellow on divided highways or one-way roads, so color also tells you which side of the road you are near.

A simple way to remember it: white on the right , yellow in the middle/left.
