Question Analysis
This question tests knowledge of lane markings from the Texas Driver Handbook. A dashed white line separates lanes of traffic moving in the same direction and indicates that lane changes are permitted. The handbook states that you may cross a dashed white line to change lanes or to enter or exit a lane, but only when you can do so safely, after checking traffic and signaling. The key concept is that the marking permits the maneuver, but the driver must ensure it is safe.
Correct Answer Analysis
Correct Answer: When it is safe to change lanes.
The correct answer is 'When it is safe to change lanes.' A dashed white line is a permissive lane marking: it allows you to cross it to change lanes, but only when traffic conditions make the move safe. Texas law requires drivers to signal and yield to traffic before changing lanes, so safety is the controlling condition.
Wrong Options Analysis
Option: At any time.
Incorrect. Even though a dashed white line permits lane changes, you may not cross it at any time. You must only do so when it is safe, after checking for other vehicles and signaling. Crossing when unsafe could cause a collision and is a violation.
Option: Only during daylight hours.
Incorrect. There is no daylight-only restriction for crossing a dashed white line. Lane changes are permitted at night as well, provided it is safe and you comply with signaling and right-of-way rules.
Option: Only when passing a motorcycle.
Incorrect. A dashed white line is not limited to passing motorcycles. It allows general lane changes when safe. Passing a motorcycle is not a special condition that changes the rule for this marking.
