Washington Written Drivers Permit Practice Test

When can you legally cross a double solid yellow line?

1. When making a right turn onto a street

2. When making a left turn into a driveway or onto the road

3. Any time during the day

4. Only if there is no traffic

The correct answer is: When making a left turn into a driveway or onto the road

Crossing a double solid yellow line is permitted primarily when you're making a left turn into a driveway or onto another road. This allows a driver to safely transition from one roadway to another or to access property while adhering to traffic regulations. The key aspect is that such maneuvers can involve crossing a traffic divider, provided the action is performed safely and with respect to surrounding traffic. In other scenarios, such as making a right turn onto a street or when considering the conditions of traffic during the day or the presence of other vehicles, the regulations maintain a strict limit on crossing double solid yellow lines. It is important for drivers to understand that these lines are intended to prevent overtaking or passing when it is unsafe, and adherence to these rules is essential for maintaining safe traffic flow.
