2006 CADILLAC CTS turn signal

Freeway Driving
Mile for mile, freeways — also called thruways, parkways,
expressways, turnpikes, or superhighways — are the
safest of all roads. But they have their own special rules.The most important advice on freeway driving is:
Keep up with traffic and keep to the right. Drive at the
same speed most of the other drivers are driving.
Too-fast or too-slow driving breaks a smooth traffic ow.
Treat the left lane on a freeway as a passing lane.
At the entrance, there is usually a ramp that leads to
the freeway. If you have a clear view of the freeway
as you drive along the entrance ramp, you should begin
to check traffic. Try to determine where you expect to
blend with the ow. Try to merge into the gap at close
to the prevailing speed. Switch on your turn signal,
check your mirrors, and glance over your shoulder as
often as necessary. Try to blend smoothly with the
traffic ow.
Once you are on the freeway, adjust your speed to
the posted limit or to the prevailing rate if it is slower.
Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there is not another vehicle in
your blind spot.
