Question

a ______ yellow line means traffic on both sides may not cross the center line to pass.
double broken
single broken
single solid
double solid

Explanation:

To solve this, we recall traffic line rules: A double solid yellow line prohibits traffic from both sides from crossing the center line to pass. Broken lines (single or double) allow passing in appropriate situations, and a single solid yellow line typically restricts one - way passing or has different passing rules, not the “both sides may NOT pass” rule as described. So the correct option is the one with double solid.

Answer:

D. double solid
