FACT
SHEET
Speeding
Approximately
6.2 million reported crashes occurred in 2004. Speeding - defined
as exceeding the posted speed limit or driving too fast for conditions
- is a factor in nearly one-third of all fatal crashes. Speed
reduces the amount of available time needed to avoid a crash,
increases the likelihood of crashing and increases the severity
of a crash once it occurs. The public needs to be made more aware
of the dangers of speeding. If we are to combat this dangerous,
life-threatening behavior, we must devote increased resources
to better enforcement, including more law enforcement officers
to patrol the highways, and we must support technological advances,
such as video cameras (also known as "photo radar"),
to target aggressive, speeding drivers.
SPEEDING
FACTS
Speeding-related
crashes resulted in 13,192 fatalities in 2004. (National Highway
Traffic Safety Administration, NHTSA, 2005)
The
economic costs of crashes that involved excessive speed were $40.4
billion, representing 18 percent of total crash costs and an average
cost of $144 for every person in the United States. (NHTSA, 2002)
When
speed increases from 40 mph to 60 mph, the energy released in
a crash more than doubles. (IIHS, 2003)
Research
by the Insurance Institute for Highway Safety (IIHS) found that
when speed limits were raised by many states in 1996, travel speeds
increased and motor vehicle fatalities went up approximately 15
percent on Interstate highways in those states.
The
relative proportion of speeding-related crashes to all crashes
decreases with increasing driver age. In 2002, 39 percent of male
drivers 15 to 20 years old who were involved in fatal crashes
were speeding at the time of the crash. (NHTSA, 2003)
Alcohol
and speeding are a deadly combination. In 2002, 42 percent of
drivers with a BAC of .08 or higher involved in fatal crashes
were speeding, compared to only 15 percent of sober drivers involved
in fatal crashes. (NHTSA, 2003)
In
2002, 38 percent of all motorcyclists involved in fatal crashes
were speeding. The percentage of speeding involvement in fatal
crashes was approximately twice as high for motorcyclists as for
drivers of passenger cars or light trucks, and the percentage
of alcohol involvement was about 45 percent higher for motorcyclists.
(NHTSA, 2003)
SPEED LIMIT LAW FACTS
When
Texas increased its speed limit from 55 mph to 70 mph, the average
speed on a sampling of Texas's urban freeways and interstate highways
increased substantially. Prior to the increase, 15 percent of
cars on these roads were exceeding 70 mph and 4 percent were exceeding
75 mph. After the speed limit increase, 50 percent were exceeding
70 mph and 17 percent were traveling faster than 75 mph. (IIHS,
2003)
When
Virginia raised its speed limit to 65 mph in 1988, the percentage
exceeding 70 mph went from 8 percent in 1988 to 39 percent by
1994. (IIHS, 2003)
In
states where speed limits were raised to 65 mph in 1987, the higher
limits are causing 15-20 percent more deaths on rural interstates
each year. In states that raised rural speed limits, more than
400 lives are lost each year because of higher limits. (IIHS,
2003)
As
of June 2003, 29 states have raised speed limits to 70 mph or
higher on portions of their roads and highways. (IIHS, 2003)
In a public opinion poll conducted by Lou Harris for Advocates
for Highway and Auto Safety in May 1996, 52 percent of those polled
said they were concerned that they will feel unsafe on the highways
because drivers would go "much faster," exceeding even
the posted limits. In a 2001 Lou Harris poll, 77 percent of those
polled said they want to see more done about speeding on local
streets and highways.
SPEED
PHOTO RADAR
Radar signals can be used to trigger cameras that photograph speeding
vehicles as they pass a specified point. These photo radar devices
use a low-powered doppler radar speed sensor to detect speeding
vehicles and trigger a motor-driven camera and flash unit to photograph
vehicles traveling faster than a set speed. Like red light cameras,
speed cameras generate photographic evidence that gives the date,
time, place and vehicle speed. Currently, only four states (AZ,
CA, CO, OR) and DC have begun using speed photo radar. (IIHS 2003)
Speed
photo radar has been used for more than 20 years in a number of
countries including Australia, Austria, Canada, Germany, Greece,
Italy, the Netherlands, Norway, South Africa, Spain, Switzerland,
and Taiwan. (IIHS, 2003)
In
Victoria, Australia, speed photo radar was introduced in late
1989, and police reported that within three months the number
of offenders triggering photo radar decreased by 50 percent. Deaths
fell 30 percent in 1990 compared with 1989. The percentage of
vehicles significantly exceeding the speed limit has decreased
from about 20 percent in 1990 to less than 4 percent in 1994.
(IIHS, 2003)
Research
from British Columbia, Canada, shows a 7.4 percent decline in
crashes and up to 20 percent fewer deaths the first year speed
photo radar was used. The proportion of speeding vehicles declined
from 66 percent in 1996 to less than 40 percent today, and researchers
also attribute a 10.5 percent decline in daytime injuries to photo
radar. (IIHS, 2003)
