lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles driving at the inner
edge of their lanes.

R
close to crash barriers or similar solid lane
borders.

extended period next to long vehicles, such as
trucks.
