Two Stage Left Turns, sometime used in conjunction with Bicycle Boxes, are areas at the front <br /> of an intersection designated for bikes. These areas are used to either allow bicyclists to move <br /> out of the path of right turn vehicles or as an alternate to making a left turn at an intersection. <br /> Figure 8: Two Stage Left Turn <br /> 1 _$ <br /> 111111111.11110 • r• •••,4.r. .•- 4 <br /> ig / — / <br /> / / I - <br /> 0 ..■-, ....... <br /> L.

Las Positas Boulevard, adjacent to Fairlands Elementary <br /> School. The buffered and protected bike lanes are similar, with the difference being that <br /> protected bike lanes have a vertical element of separation between the vehicles and bicycles. <br /> This vertical element can take on many different designs, such as thin delineators or concrete <br /> curbs with landscaping to parked vehicles. <br /> Image 3: Protected Bike Lane Examples <br /> _i_ 1 I. lr . <br /> . 4. .1'. ,ii - '4 4064""- .
