Re: California Lane Sharing ticket CVC 21658(a)
First, the section:
21658. Whenever any roadway has been divided into two or more
clearly marked lanes for traffic in one direction, the following
(a) A vehicle shall be driven as nearly as practical entirely
within a single lane and shall not be moved from the lane until such
movement can be made with reasonable safety.
(b) Official signs may be erected directing slow-moving traffic to
use a designated lane or allocating specified lanes to traffic
moving in the same direction, and drivers of vehicles shall obey the
directions of the traffic device.
So ... what exactly did he say you did? It sounds like he is accusing you of straddling the line. If so, and this was not part of an active and safe turning movement, then the violation as cited would seem to be appropriate appropriate. You cannot straddle the lane.
This concept of "lane sharing" (whatever that is) would seem to be irrelevant. If, by that, you think that it is lawful for two vehicles to be in the same lane of traffic effectively side by side, you are likely to be incorrect ... depending on the circumstances. There are laws that govern the lawful passing of other vehicles and where a vehicle is to be within the lane. But, without seeing the stretch of road or the circumstances, and since it is not the issue here, the question is moot.
Question: Are you driving an auto? Or are you driving a motorcycle?
