Your Driving and the Road
Traffic Lights
AM402014
We’re all familiar with traffic lights or stop lights. Often, green arrow\
s are
being used in the lights for improved traffic control. On some multilane road\
s,
green arrows light up, indicating that traffic in one
or more lanes can move or
make a turn. Green arrows don’t mean “go no matter what.\
” You’ll still need
to proceed with caution, yielding the right
of way to pedestrians and
sometimes to other vehicles.
Some traffic lights also use red arrows to signify that you must stop before
turning on red.
