Motorcycle Accident Cause Factors and Identification
of Countermeasures
A motorcycle accident study offers you and your students
a wealth of information about accidents and how to avoid them. The "Motorcycle
Accident Cause Factors and Identification of Countermeasures," is a study
conducted by the University of Southern California (USC). With funds from
the National Highway Traffic Safety Administration, researcher Harry Hurt
investigated almost every aspect of 900 motorcycle accidents in the Los
Angeles area. Additionally, Hurt and his staff analyzed 3,600 motorcycle
traffic accident reports in the same geographic area.
Reprinted here for your information and use are the
findings.
The final report is several hundred pages. If you

"Motorcycle Accident Cause Factors and Identification
of Countermeasures"
Findings
Throughout the accident and exposure data there are
special observations which relate to accident and injury causation and
characteristics of the motorcycle accidents studied. These findings are
summarized as follows:
-
Approximately three-fourths of these motorcycle accidents
involved collision with another vehicle, which was most usually a passenger
automobile.
-
Approximately one-fourth of these motorcycle accidents
were single vehicle accidents involving the motorcycle colliding with the
roadway or some fixed object in the environment.
-
Vehicle failure accounted for less than 3% of these
motorcycle accidents, and most of those were single vehicle accidents where
control was lost due to a puncture flat.
-
In the single vehicle accidents, motorcycle rider error
was present as the accident precipitating factor in about two-thirds of
the cases, with the typical error being a slideout and fall due to overbraking
or running wide on a curve due to excess speed or under-cornering.
-
Roadway defects (pavement ridges, potholes, etc.) were
the accident cause in 2% of the accidents; animal involvement was 1% of
the accidents.
-
In the multiple vehicle accidents, the driver of the
other vehicle violated the motorcycle right-of-way and caused the accident
in two-thirds of those accidents.
-
The failure of motorists to detect and recognize motorcycles
in traffic is the predominating cause of motorcycle accidents. The driver
of the other vehicle involved in collision with the motorcycle did not
see the motorcycle before the collision, or did not see the motorcycle
until too late to avoid the collision.
-
Deliberate hostile action by a motorist against a motorcycle
rider is a rare accident cause.
-
The most frequent accident configuration is the motorcycle
proceeding straight then the automobile makes a left turn in front of the
oncoming motorcycle.
-
Intersections are the most likely place for the motorcycle
accident, with the other vehicle violating the motorcycle right-of-way,
and often violating traffic controls.
-
Weather is not a factor in 98% of motorcycle accidents.
-
Most motorcycle accidents involve a short trip associated
with shopping, errands, friends, entertainment or recreation, and the accident
is likely to happen in a very short time close to the trip origin.
-
The view of the motorcycle or the other vehicle involved
in the accident is limited by glare or obstructed by other vehicles in
almost half of the multiple vehicle accidents.
-
Conspicuity of the motorcycle is a critical factor in
the multiple vehicle accidents, and accident involvement is significantly
reduced by the use of motorcycle headlamps (on in daylight) and the wearing
of high visibility yellow, orange or bright red jackets.
-
Fuel system leaks and spills were present in 62% of
the motorcycle accidents in the post-crash phase. This represents an undue
hazard for fire.
-
The median pre-crash speed was 29.8 mph, and the median
crash speed was 21.5 mph, and the one-in-a-thousand crash speed is approximately
86 mph.
-
The typical motorcycle pre-crash lines-of-sight to the
traffic hazard portray no contribution of the limits of peripheral vision;
more than three-fourths of all accident hazards are within 45deg of either
side of straight ahead.
-
Conspicuity of the motorcycle is most critical for the
frontal surfaces of the motorcycle and rider.
-
Vehicle defects related to accident causation are rare
and likely to be due to deficient or defective maintenance.
-
Motorcycle riders between the ages of 16 and 24 are
significantly overrepresented in accidents; motorcycle riders between the
ages of 30 and 50 are significantly underrepresented.
-
Although the majority of the accident-involved motorcycle
riders are male (96%), the female motorcycles riders are significantly
overrepresented in the accident data.
-
Craftsmen, laborers, and students comprise most of the
accident-involved motorcycle riders. Professionals, sales workers, and
craftsmen are underrepresented and laborers, students and unemployed are
overrepresented in the accidents.
-
Motorcycle riders with previous recent traffic citations
and accidents are overrepresented in the accident data.
-
The motorcycle riders involved in accidents are essentially
without training; 92% were self-taught or learned from family or friends.
Motorcycle rider training experience reduces accident involvement and is
related to reduced injuries in the event of accidents.
-
More than half of the accident-involved motorcycle riders
had less than 5 months experience on the accident motorcycle, although
the total street riding experience was almost 3 years. Motorcycle riders
with dirt bike experience are significantly underrepresented in the accident
data.
-
Lack of attention to the driving task is a common factor
for the motorcyclist in an accident.
-
Almost half of the fatal accidents show alcohol involvement.
-
Motorcycle riders in these accidents showed significant
collision avoidance problems. Most riders would overbrake and skid the
rear wheel, and underbrake the front wheel greatly reducing collision avoidance
deceleration. The ability to countersteer and swerve was essentially absent.
-
The typical motorcycle accident allows the motorcyclist
just less than 2 seconds to complete all collision avoidance action.
-
Passenger-carrying motorcycles are not overrepresented
in the accident area.
-
The driver of the other vehicles involved in collision
with the motorcycle are not distinguished from other accident populations
except that the ages of 20 to 29, and beyond 65 are overrepresented. Also,
these drivers are generally unfamiliar with motorcycles.
-
The large displacement motorcycles are underrepresented
in accidents but they are associated with higher injury severity when involved
in accidents.
-
Any effect of motorcycle color on accident involvement
is not determinable from these data, but is expected to be insignificant
because the frontal surfaces are most often presented to the other vehicle
involved in the collision.
-
Motorcycles equipped with fairings and windshields are
underrepresented in accidents, most likely because of the contribution
to conspicuity and the association with more experienced and trained riders.
-
Motorcycle riders in these accidents were significantly
without motorcycle license, without any license, or with license revoked.
-
Motorcycle modifications such as those associated with
the semi-chopper or cafe racer are definitely overrepresented in accidents.
-
The likelihood of injury is extremely high in these
motorcycle accidents-98% of the multiple vehicle collisions and 96% of
the single vehicle accidents resulted in some kind of injury to the motorcycle
rider; 45% resulted in more than a minor injury.
-
Half of the injuries to the somatic regions were to
the ankle-foot, lower leg, knee, and thigh-upper leg.
-
Crash bars are not an effective injury countermeasure;
the reduction of injury to the ankle-foot is balanced by increase of injury
to the thigh-upper leg, knee, and lower leg.
-
The use of heavy boots, jacket, gloves, etc., is effective
in preventing or reducing abrasions and lacerations, which are frequent
but rarely severe injuries.
-
Groin injuries were sustained by the motorcyclist in
at least 13% of the accidents, which typified by multiple vehicle collision
in frontal impact at higher than average speed.
-
Injury severity increases with speed, alcohol involvement
and motorcycle size.
-
Seventy-three percent of the accident-involved motorcycle
riders used no eye protection, and it is likely that the wind on the unprotected
eyes contributed in impairment of vision which delayed hazard detection.
-
Approximately 50% of the motorcycle riders in traffic
were using safety helmets but only 40% of the accident-involved motorcycle
riders were wearing helmets at the time of the accident.
-
Voluntary safety helmet use by those accident-involved
motorcycle riders was lowest for untrained, uneducated, young motorcycle
riders on hot days and short trips.
-
The most deadly injuries to the accident victims were
injuries to the chest and head.
-
The use of the safety helmet is the single critical
factor in the prevention of reduction of head injury; the safety helmet
which complies with FMVSS 218 is a significantly effective injury countermeasure.
-
Safety helmet use caused no attenuation of critical
traffic sounds, no limitation of precrash visual field, and no fatigue
or loss of attention; no element of accident causation was related to helmet
use.
-
FMVSS 218 provides a high level of protection in traffic
accidents, and needs modification only to increase coverage at the back
of the head and demonstrate impact protection of the front of full facial
coverage helmets, and insure all adult sizes for traffic use are covered
by the standard.
-
Helmeted riders and passengers showed significantly
lower head and neck injury for all types of injury, at all levels of injury
severity.
-
The increased coverage of the full facial coverage helmet
increases protection, and significantly reduces face injuries.
-
There is not liability for neck injury by wearing a
safety helmet; helmeted riders had less neck injuries than unhelmeted riders.
Only four minor injuries were attributable to helmet use, and in each case
the helmet prevented possible critical or fatal head injury.
-
Sixty percent of the motorcyclists were not wearing
safety helmets at the time of the accident. Of this group, 26% said they
did not wear helmets because they were uncomfortable and inconvenient,
and 53% simply had no expectation of accident involvement.
-
Valid motorcycle exposure data can be obtained only
from collection at the traffic site. Motor vehicle or driver license data
presents information which is completely unrelated to actual use.
Less than 10% of the motorcycle riders involved
in these accidents had insurance of any kind to provide medical care or
replace property.

Riding Texas Highways
Motorcycling is very popular in Texas. We have one
of the largest motorcycle populations in the United States. Before you
take to the road, you should know the Texas laws governing motorcycles,
and the common sense safety rules. Experienced and knowledgeable motorcyclists
would rather be riding then fighting a legal battle or recovering from
a crash.
If you have never ridden a motorcycle, you
should know that a motorcycle only looks easy to ride. Motorcycles are
different from other vehicles - only two wheels places more demand on the
operator for balance and coordination. The motorcycle's smaller size makes
it harder for others to see it in traffic and more vulnerable to injury
in a crash. Riding a motorcycle requires special skills and knowledge beyond
those required for driving a car.
On today's highways, there are large number
of motorcycle riders and even larger numbers of automobile drivers who
do not understand how to safely mix in traffic. This lack of knowledge
resulted in an increase in motorcycle-related crashes. The key to safety
is understanding and learning how to share the roadway.
Knowing all you can about the motorcycle you ride,
or intend to ride, is good preparation for safe and enjoyable riding. Learning
to ride off the street in "The Course for Motorcycle Riders" is good insurance.
When you take to the road, you will be able to concentrate on the traffic
because control of the motorcycle becomes second nature with the proper
instruction.
There are plenty of things on the highway that can
cause you trouble. Your motorcycle should not be one of them. Three ways
to be sure your motorcycle won't let you down are:
-
Make sure you have the right equipment to begin with.
-
Keep your motorcycle in safe riding condition.
-
Avoid adding accessories or making modifications that
make your motorcycle harder to handle.
Equipment
Texas Law requires the following equipment on Motorcycles
and Motor Driven Cycles:
| 1. Wheel Assembly |
8. Motorcycle, Serial, or Vehicle Identification
Number |
| 2. Exhaust System |
9. Horn |
| 3. Tail Lamp (1) |
10. Mirror |
| 4. Stop Lamp (1) |
11. Steering |
| 5. License Plate Lamp |
12. Brakes |
| 6. Rear Red Reflector |
13. Tires |
| 7. Head Lamp (1) |
|
Texas Law requires the following equipment on
Mopeds:
| 1. Brake |
3. Head Lamp |
| 2. Reflector |
4. Rear Lamp |
These are just minimum requirements. To survive in traffic,
you should have a mirror on each side. It is also a good idea to have additional
reflectors on the motorcycle.
Helmets and Passengers
- Helmets meeting the Federal Motor Vehicle Safety Standard #218 (FMVSS-218)
are required for a motorcycle operators and passengers. Persons at least
21 years old are exempt from wearing a helmet is they have completed a
Department-approved motorcycle operator training course or they are covered
with at least $10,000 in medical insurance. Persons operating or riding
upon a motorcycle with a helmet exemption sticker displayed are presumed
to meet the helmet exemption requirements.
Helmets should also:
-
Fit snugly
-
Be securely fastened when riding
-
Be free of defects such as cracks, loose padding, frayed
straps, or exposed metal.
A motorcycle operator cannot carry a passenger unless
the motorcycle is equipped with a permanent passenger seat.
Licensing and Operation
Adult Motorcycle Operator Licensing
The operator of a motorcycle on a public roadway
must hold a valid motorcycle license (Class M Driver License). This requirement
also applies to operators of scooters.
To receive a license to operate a motorcycle, applicants
must pass a written test covering traffic laws pertaining to motorcycles,
and a road test. The road test may be waived.
Road Test and Waiver Information
In order to take a road test, applicants must have
their own motorcycle and provide a passenger vehicle and a licensed driver
to drive the examiner during the road test. The vehicle owners must show
proof of liability insurance for both vehicles and must pass an on-site
safety inspection.
An applicant who has passed a Department of Public
Safety approved basic motorcycle operator training course, and has an unrestricted
(not an instructional permit) class A, B, or C license, can present a an
MSB-8 completion certificate and receive a waiver of the road test.
Requirements for Licensing Minors
Texas law requires that minors, ages 15 through 17
pass a basic motorcycle operator training course approved by the Department
of Public Safety before applying for a motorcycle license. Before taking
the course, minors must have successfully completed the classroom phase
of a driver education course. A minor must present the MSB-8 before testing
for a motorcycle license.
Minors over the age of 16 who already have an unrestricted
Class A, B, or C driver license are eligible for a road test waiver. Minors
under the age of 16 can only be licensed to ride a motorcycle with no more
than 125cc piston displacement. This restriction is indicated by the restriction
code "I" on the driver's license. After the person reaches the age of 16,
the 125cc restriction may be removed.
Mopeds - The operator of a moped must
hold a valid license as a moped operator (Class M driver license with a
restriction code of "K"). A moped is defined as a motor driven cycle that
cannot exceed 30 mph, does not have an engine larger than 50cc, and does
not have manual gear shifting. Applicants for a moped operator's license
must be at least 15 years old. The licensing requirements involve a written
examination on traffic laws that apply to the operation of mopeds. No road
test involving the operation of a moped is required.
Registration - Every owner of a motor
vehicle, including motorcycles, motor scooters, and mopeds that will be
ridden on public roadways, must register their vehicle through the County
Tax Collector in their county of residence. A license plate must be attached
to the rear of the vehicle, and must include a sticker showing current
registration.
Inspection - All motor vehicles registered
in Texas, including motorcycles, motor scooters, and mopeds, must be inspected
each year at an official motor vehicle inspection station. When the motorcycle
passes inspection, an approved certificate must be placed near the rear
license plate. These certificates are good for one year from the month
of inspection.
Insurance - All motor vehicle operators
must show proof of liability insurance when the vehicle is registered or
inspected, or when getting an operator license.
Be Road Ready
Studies indicate that in crashes, motorcycle riders
and passengers are more likely to be seriously injured or killed than automobile
operators or passengers. Your chance of reaching your destination safely
is directly related to the preparation you do before the ride. You need
to mentally prepare by being alert, free of stress, sober, and ready for
riding.
Head Protection - A helmet protects
you against head injury, windblast, cold, sunburn, flying objects, and
hearing loss. Head injuries account for the majority of motorcycle fatalities.
Without a helmet, you are five times more likely to sustain a critical
head injury in a crash.
Eye Protection - Eyeglasses with shatterproof
lenses protect the eyes but most styles do not seal out the wind that makes
your eyes water. Goggles provide eye protection and most models protect
your eyes from the wind. A motorcycle windshield or fairing alone is not
adequate for eye protection. Eye protection should:
-
Be shatterproof
-
Be securely fastened
-
Be optically clear
-
Resist impact and penetration
-
Not block peripheral vision
Protective Clothing - The clothes you
wear when riding a motorcycle should protect you from sunburn, windburn,
rain, dehydration, cold, and parts of the motorcycle, and provide visibility
and comfort. In case of a crash, quality riding clothes may prevent or
reduce the severity of cuts, abrasions, and bodily injury. Quality riding
clothes consist of:
-
Low-heeled footwear that covers the ankle with no dangling
laces or rings and provides a good grip on the road surface and footpegs.
-
Gloves that protect the hands from cuts and bruises,
blisters, cold, wind, and provide better grip for control.
-
Brightly colored long-sleeved shirt or jacket and long
pants that will resist abrasions and fit comfortably without binding.
-
Rain suits are recommended in rainy weather.
Face Shields - Any motorcyclist who has
been hit in the face by a stone or an insect while riding can tell you
about the benefits of face protection. Studies indicate that motorcycle
riders with shields covering their faces suffer fewer facial injuries than
others without a shield. A face shield should:
-
Be securely fastened to the helmet and be free of scratches.
-
Resist impact and penetration.
Frequently Asked Questions
Q. What is "The Course for Motorcycle Riders?"
A. The Basic Motorcycle Operator Training Course
teaches the mental and physical skills that new, or inexperienced, riders

Training Course is for the more experienced rider and teaches more advanced
street survival skills. Both courses are approved by the Department of
Public Safety and offered by contracted sponsors participating in the Texas
Motorcycle Operator Training Program.
Q. Who is required to take the course?
A. Minors, 15 through 17 years old, must complete
the Basic Motorcycle Operator Training Course to be eligible to receive
a motorcycle operator's license. Riders of all ages are encouraged to take
it.
Q. When and where are the courses offered?
A. Course schedules vary both in days and times offered.
Courses are available in more then 40 throughout the state. Call toll free
in Texas 1/800-292-5787 or (512) 424-2021 (in Austin) to find the course
