Which pavement marking indicates that lane changes are not allowed?

• A. Double solid line
• B. Single solid line
• C. Single broken line
• D. Diamond marking

Answer: (A)

The indication that lane changes are not allowed is clearly represented by a double solid line. This marking is specifically used to discourage or prohibit vehicles from crossing over to the opposite lane. When drivers observe a double solid line, it signifies that both directions of traffic must remain in their designated lanes and that changing lanes is illegal and unsafe in that area. In contrast, a single solid line generally indicates that crossing is discouraged but not illegal. A single broken line signifies that lane changes are permitted, while a diamond marking is typically used to designate reserved lanes, such as those for high-occupancy vehicles. Therefore, the double solid line is the definitive marking that communicates no lane changes should occur, reinforcing safe driving practices.
