Have you ever wondered what the purpose of rumble strips are? Do they even keep drivers from crashing? What exactly are they? To find out, read this slide!

1. They’re more important than you think!

2. A
series of raised strips (or “bumps”)
placed along the edge of a road or in the
center of a road.

3.  They
change
the noise a
car’s tires make
on the road to
alert the driver
he is unsafely
crossing
boundaries.

4.  By
being in the middle of the road, center rumble
strips warn drivers they are crossing into oncoming traffic.

5.  Shoulder
rumble
strips alert drivers
they are drifting off
the road, which
can be especially
dangerous if there
are steep cliffs or
large trees.

6.  Drivers
get distracted, drowsy, inattentive
and intoxicated. Rumble strips can help
wake up and alert these types of drivers.
 They also help drivers know where they
are in bad weather conditions.
 If your city’s roads need more rumble
strips, contact your city’s leaders.
