Changing Lanes in Intersections
I am often asked to tell the motoring public that it is illegal to change lanes in an intersection. I cannot do this, because there is no specific rule prohibiting this driving action in the Motor Vehicle Act. However, a defensive driver will choose not to do this, even if it is legal.
The Motor Vehicle Act prohibits lane changes when doing so is unsafe or will affect the travel of another vehicle. In addition a driver must not change lanes if it means crossing a solid line. If there is no traffic in or near the intersection the lane change would be allowed as solid lines are not usually painted within intersections.
Keeping in mind that more than 50% of collisions in British Columbia occur in intersections, it is wise to keep vehicle movements there uncomplicated. This is why defensive driving prohibits making a lane change within the intersection. The choice removes one element of uncertainty for other drivers and that creates a safer driving environment.
In summary, choose the lane you want to use and occupy it well in advance of the intersection. If you decide that it is not the correct lane to use after all, wait until you are well clear of the intersection and then change lanes again as necessary.
