Delaware Defensive Driving Practice Test

A solid yellow line signifies no passing zones. This marking indicates that drivers should not cross the line to pass another vehicle, as it is not safe to do so due to visibility issues or other hazards that may be present on the road. The presence of a solid yellow line serves as a warning about the dangers of overtaking, ensuring that drivers are aware of the potential risks involved in attempting to pass in areas where visibility is restricted. The other options do not accurately represent the meaning of a solid yellow line. Opposite direction traffic is often indicated by a broken yellow line, while one-way traffic is typically denoted by different signage or road markings. Turn lanes are also marked differently, often using dashed lines that signal where it’s permissible to change lanes or turn. Thus, understanding the significance of the solid yellow line helps maintain road safety by preventing unsafe passing maneuvers.
