Traffic Fatalities 2012 Statistics from the CDC
(Centers for Disease Control): For ages 5–24 Motor Vehicle Crashes are
the #1 Cause of Injury Deaths For ages 25-65+ Motor Vehicle Crashes
are the #2 Cause of Injury Deaths In 2012 2.5 Million persons were treated
for a traffic injury at a cost of $80 Billion

Distracted and Fatigued Driving Crashes resulting from distraction
or drowsiness (fatigue): Are usually run-off-road collisions, head-on
collisions, or rear-end collisions Result in higher injury and fatality rates Are less likely to show evidence of the
drivers trying to avoid the collision Such as skid marks, for example

Safety Benefits of Rumble Stripes Peer-Reviewed Traffic Safety Studies
Shoulder Rumble Strips (e.g. Edge Line Rumble Stripes) reduce Run-Off-Road Fatal and Injury Crashes by 36% on Rural 2-lane Roads (on average)2
Centerline Rumble Stripes reduce Head-On Fatal and Injury Crashes by 44% on Rural 2-lane Roads (on average)2
Rumble Stripe Noise Considerations Admittedly, noise levels near the
roadway can sometimes be objectionable.
However, the lives that can be saved by rumble stripes must be balanced against this drawback.
According to a 2007 study, 13% of the peak rumble stripe noise levels were above the highest noise level measured for a commercial vehicle driving along the roadway (not hitting the rumble stripes)3
FHWA Guidance FHWA recommends and provides
funding for the following INDOT safety programs: Centerline rumble stripes system-wide on
undivided rural roads with posted speeds of 50 mph or greater (where the sum of the lane and shoulder width for each travel direction is at least 14 feet)2
Edge line or shoulder rumble stripes system-wide on rural highways with posted or statutory speeds of 50 mph or greater2
