Washington Written Drivers Permit Practice Test

When driving straight through a roundabout in Washington, it is recommended to use either the left or right lane, depending on which lane you have entered from. The correct answer, option D, allows flexibility for drivers to choose either the left or right lane based on their entry point into the roundabout. This ensures a smooth flow of traffic and helps prevent unnecessary lane changes within the roundabout. Options A, B, and C are incorrect because in a situation where you want to drive straight through a roundabout, you are not limited to using just the left lane, right lane, or the innermost lane specifically. Choosing either the left lane or right lane provides drivers with the opportunity to navigate the roundabout effectively and exit at their desired point without causing disruptions to the traffic flow.
