YOUR VEHICLE
SIGN, POLE, etc.
Because of the road condition
(curved, winding, etc.) or the state of
your vehicle (turning angle, lane
position, etc.), CMBS can sometimes
mistake a stationary object (light pole,
traffic sign, guard rail, etc.) as a
vehicle ahead of you and temporarily
operate. This is normal.
