Saskatchewan SGI Driving Practice Test

Under what circumstance is it acceptable to cross a double solid yellow line?

1. To pass another vehicle safely

2. When turning left into a driveway

3. When preparing to exit the highway

4. It is never permissible

The correct answer is: When turning left into a driveway

The correct answer is that it is acceptable to cross a double solid yellow line when turning left into a driveway. Double solid yellow lines indicate that lane changes and passing are generally prohibited due to the risks associated with crossing into oncoming traffic. However, there are specific exceptions where crossing these lines is permitted, and making a left turn into a driveway is one of them. This action is necessary to allow drivers to access private property, businesses, or residences directly, and it is considered a safe maneuver as long as it’s performed correctly and without interfering with oncoming traffic. In contrast, crossing the lines to pass another vehicle or when preparing to exit the highway is not permitted, as these actions could lead to unsafe conditions. Double solid yellow lines are intended to minimize the risk of collisions, especially on roads where visibility is limited or where the speed limit is high. Recognizing and adhering to these regulations helps ensure the safety of all road users.
