Which line indicates that you cannot cross?

A solid yellow line indicates that you cannot cross it to pass another vehicle. This line is used to separate lanes of traffic moving in opposite directions, and its solid nature signifies that overtaking another vehicle is prohibited due to potential dangers in the area, such as curves or limited visibility. Drivers should remain in their lane and refrain from crossing the solid yellow line to ensure safety on the road.

In contrast, broken yellow lines indicate that passing is allowed when safe, while solid white lines are used to separate lanes of traffic moving in the same direction and may sometimes indicate that lane changes are discouraged. A broken white line allows for lane changes and does not restrict movement between lanes. Understanding these markings is essential for safe driving practices and compliance with traffic laws.
