How many broken white lines are in a mile?

Answer 1

One mile is 5,280 feet. Measure one white line and one space between the lines and add them together. Divide that sum into 5,280 and then divide by 2 and subtract 1. (assuming the length of the lines and spaces are the same.) ex: line = 5ft, space = 5ft. divide 5,280 by 10 = 528 - 1 = 527 white lines. CORRECT ANSWER: Since per the department of transportation regulations, the length of a white line is 20 feet long with a 10 foot space between the white lines, you get one white line every 30 feet, divide 5280 by 30 and you get 176 white lines per mile.

Answer 2

There are approximately 9,280 broken white lines in a mile. This is based on the standard length of a broken white line on a road, which is typically around 10 feet.

Answer 3

Per US federal guidelines, each dashed line measures 10 feet, and the empty spaces in-between measure 30 feet. Every time a car passes a new dashed line, the car has traveled 40 feet. In a mile the car will pass 132 dashed lines.
