Speeding is one of the most prevalent factors contributing to traffi c crashes. The
economic cost to society of speeding-related crashes is estimated by NHTSA to be
$40.4 billion per year. In 2003, speeding was a contributing factor in 31 percent of
all fatal crashes, and 13,380 lives were lost in speeding-related crashes.
Motor vehicle crashes cost society an estimated $7,300 per second. The total
economic cost of crashes was estimated at $230.6 billion in 2000. The 2000 costs of
speeding-related crashes
were estimated to be $40.4 billion — $76,865 per minute
or $1,281 per second.
Speeding reduces a driver’s ability to steer safely around curves or objects in
the roadway, extends the distance necessary to stop a vehicle, and increases the
distance a vehicle travels while the driver reacts to a dangerous situation.

“The economic cost

of speeding-related

crashes is estimated

to be $40.4 billion

each year.”

NHTSA considers a crash to be speeding-related if the driver was charged with a

speeding-related offense or if an officer indicated that racing, driving too fast for

conditions, or exceeding the posted speed limit was a contributing factor in the

crash.

Speeding is one of the most prevalent factors contributing to traffic crashes. The

economic cost to society of speeding-related crashes is estimated by NHTSA to be

$40.4 billion per year. In 2003, speeding was a contributing factor in 31 percent of

all fatal crashes, and 13,380 lives were lost in speeding-related crashes.

Motor vehicle crashes cost society an estimated $7,300 per second. The total

economic cost of crashes was estimated at $230.6 billion in 2000. The 2000 costs of

speeding-related crashes were estimated to be $40.4 billion — $76,865 per minute

or $1,281 per second.

Speeding reduces a driver’s ability to steer safely around curves or objects in

the roadway, extends the distance necessary to stop a vehicle, and increases the

distance a vehicle travels while the driver reacts to a dangerous situation.

Figure 1 Fatal Crashes by Speeding Status, 1993-

“In 2003, 39 percent

of male drivers 15 to

20 years old involved

in fatal crashes were

speeding.”

For drivers involved in fatal crashes, young males are the most likely to be

speeding. The relative proportion of speeding-related crashes to all crashes

decreases with increasing driver age. In 2003, 39 percent of the male drivers

15 to 20 years old who were involved in fatal crashes were speeding at the time

of the crash.

Alcohol and speeding are clearly a deadly combination. Alcohol involvement is

prevalent for drivers involved in speeding-related crashes. In 2003, 41 percent of

the drivers with a blood alcohol concentration (BAC) of 0.08 grams per deciliter

(g/dl) or higher involved in fatal crashes were speeding, compared with only 14

percent of the drivers with BAC 0.00 involved in fatal crashes.

Alcohol and speeding seem to go hand in hand. In 2003, 28 percent of the speed-

ing drivers under 21 years old who were involved in fatal crashes also had a BAC

of 0.08 g/dl or higher. In contrast, only 13 percent of the nonspeeding drivers un-

der age 21 involved in fatal crashes in 2003 had a BAC of 0.08 g/dl or higher.

For drivers between 21 and 24 years of age who were involved in fatal crashes in

2003, 50 percent of speeding drivers had a BAC of 0.08 g/dl or higher, compared

with only 24 percent of nonspeeding drivers.

“Speeding involvement

for motorcyclists in

fatal crashes was

about twice the rate

for drivers of passenger

cars or light trucks.”

Total Fatality Rate per 100 Million Vehicle Miles Traveled

In 2003, 36 percent of all motorcyclists involved in fatal crashes were speeding,

approximately twice the rate for drivers of passenger cars or light trucks. The

percentage of alcohol involvement was 40 percent higher for motorcyclists than

for drivers of passenger vehicles.

In 2003, only 46 percent of speeding passenger vehicle drivers under 21 years old

who were involved in fatal crashes were wearing safety belts at the time of the

crash. In contrast, 67 percent of nonspeeding drivers in the same age group were

restrained. For drivers 21 years and older, the percentage of speeding drivers

involved in fatal crashes who were using restraints at the time of the crash was

43 percent, but 71 percent of nonspeeding drivers in fatal crashes

were restrained.

In 2003, 22 percent of speeding drivers involved in fatal crashes had an

invalid license at the time of the crash, compared with 10 percent of

nonspeeding drivers.

Speeding was a factor in 29 percent of the fatal crashes that occurred on dry

roads in 2003 and in 34 percent of those that occurred on wet roads. Speeding

was a factor in 52 percent of the fatal crashes that occurred when there was snow

or slush on the road and in 58 percent of those that occurred on icy roads.

Speeding was involved in more than one-third (36 percent) of the fatal crashes

that occurred in construction/maintenance zones in 2003.

In 2003, 86 percent of speeding-related fatalities occurred on roads that were not

Interstate highways.

Figure 7 Speeding-Related Fatalities by Road Type, 2003

“Among drivers in

fatal crashes in 2003,

those who were not

speeding were about 65

percent more likely to

be wearing safety belts

than those who were

speeding at the time of

the crash.”

“Only 14 percent

of speeding-related

fatalities occur on

Interstate highways.”
