lane to an occupied adjacent lane
Lane Change Assist cannot always clearly
detect if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free.
Before changing lanes, make sure that
#
the neighboring lane is free and there is
no danger to other road users.
Monitor the lane change.
