Massachusetts Permit Practice Test

Passing on both sides of a highway is not allowed when both sides have solid yellow line markings. Solid yellow lines indicate that passing is illegal in both directions. These markings are used to denote that the road is either too dangerous for passing due to limited visibility, a lack of adequate space, or other hazards that require vehicles to remain in their lanes. While factors such as speed limit signs, road work signs, or wet conditions may influence driving behavior, they do not directly prohibit passing like solid yellow lines do. Speed limit signs inform drivers of safe operating speeds, road work signs indicate potential hazards or changes in road conditions, and wet conditions caution drivers to reduce speed and increase following distance. However, these factors do not create a definitive rule against passing as solid yellow lines do.
