Question Analysis

In Alberta, a single solid white line between traffic lanes indicates that lane changes are prohibited. This rule is outlined in the Alberta Driver's Guide, which states that a solid white line is used to discourage or prohibit lane changing, especially in areas where such maneuvers could be hazardous, such as urban roads with heavy traffic or near intersections. Drivers must not cross a solid white line unless directed by a police officer or when necessary to avoid an obstruction.

Correct Answer Analysis

Correct Answer: Changing lanes is not permitted

The correct answer is 'Changing lanes is not permitted' because a single solid white line is a regulatory pavement marking that legally prohibits crossing it. In Alberta, this marking is used to separate lanes where lane changes are unsafe, such as in urban areas with high traffic density. Crossing a solid white line is a traffic violation and can lead to fines or penalties.

Wrong Options Analysis

Option: It is a line dividing traffic moving in opposite directions

This is incorrect because a line dividing traffic moving in opposite directions is typically a solid double yellow line or a single yellow line, not a solid white line. White lines separate traffic moving in the same direction, such as lanes on a multi-lane road.

Option: Traffic on the right is moving faster than on the left

This is incorrect because pavement markings do not indicate relative speeds of traffic. Speed differences are not conveyed by lane markings; they are determined by posted speed limits and traffic conditions. This option is a distractor and has no basis in traffic law.

Option: Changing lanes is permitted

This is incorrect because a solid white line explicitly prohibits lane changes. In Alberta, crossing a solid white line is illegal unless in an emergency or directed by an authority. Therefore, saying that changing lanes is permitted contradicts the meaning of the marking.
