So here are some tips for passing:
"Drive ahead:' Look down the road, to the sides, and
to crossroads for situations that might affect your
passing patterns. If you have any doubt whatsoever
about making a successful pass, wait for a better time.
Watch for traffic signs, pavement markings, and lines.
If you can
see
a sign up ahead that might indicate
a
turn or an intersection, delay your pass. A broken
center line usually indicates it's all right to pass
(providing the road 'ahead is clear). Never cross a solid
line on your side of the lane or a double solid line, even
if the road seems empty of approaching traffic.
If you suspect that the driver of the vehicle you want to
pass isn't aware of your presence, tap the horn a couple
of times before passing.
Do not get too close to the vehicle you want to pass
while you're awaiting an opportunity. For one thing,
following too closely reduces your area
of
vision,
especially if you're following a larger vehicle. Also,
you won't have adequate space if the vehicle ahead
suddenly slows or stops. Keep back a reasonable
distance.
When it looks like a chance to pass is coming up, start
to accelerate but stay in the right lane and don't get too
close. Time your move so you will be increasing speed
as the time comes to move into the other lane. If the
way is clear to pass,
you will
have
a "running start''
that more than makes up for
the
distance you would
lose by dropping back. And if something happens to
cause you to cancel your pass, you need only slow
down and drop back again and wait for another
opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn't trying
to
pass you as you pull out to pass the slow vehicle.
Remember to glance over your shoulder and check the
blind spot.
start your left lane change signal before moving out of
the right lane to pass. When you are far enough ahead
of the passed vehicle to see its front in your inside
mirror, activate your right lane change signal and move
back into the right lane. (Remember that your right
outside mirror is convex. The vehicle you just passed
may seem to be farther away from you than it really is.)
T r y not to pass more than one vehicle at a time on
two-
lane roads. Reconsider before passing the next vehicle.
Check your mirrors, glance over your shoulder, and
