Abstract:
This report describes the development,
administration and results of a questionnaire study of drivers of
articulated vehicles. The study had three aims
- to collect information about
driving behaviours and safety-related attitudes
- to compare the behaviours and
attitudes of drivers who had been involved in injury
crashes with those who had not been involved to identify
problem areas warranting review
- to provide information about how to
effectively communicate with target groups.
Crash-involved drivers had poor coping
behaviours in relation to driver fatigue but rated their ability
in this area highly, had less often received training and were
less likely to check their truck daily. Behaviours and attitudes
related to speed judgement, behaviour of other road users, drug
taking and alcohol were similar for the two groups.
In regard to communication with drivers,
the study recommended that the use of intermediary organisations
to disse4ninate information from VIC ROADS to drivers.
Acknowledging the skills of drivers and appealing to their
professionalism may also be a successful technique.
Drivers wanted to be better at keeping
calm when held up on the road and felt that car drivers should be
trained not to cut in on them and that an endorsed licence should
be required for towing a caravan.
Executive Summary
This report describes the development,
administration and results of a questionnaire study of drivers of
articulated vehicles. The study had three aims
1. to collect information about driving
behaviours and safety-related attitudes
2. to compare the behaviours and
attitudes of drivers who had been involved in injury crashes with
those who had not been involved to identify problem areas
warranting review
3. to provide information about how to
effectively communicate with target groups.
The behaviours and attitudes studied
were related to
- Vehicle characteristics
- Training
- Speed judgement
- Hours of driving
- Driving stresses and coping
strategies
- Drug taking
- Alcohol
- Health
- Financial position
The main findings of the questionnaire
study were:
- crash-involved drivers had poor
coping behaviours in relation to driver fatigue but rated
their ability in this area highly
- training was less common among
crash-involved drivers
- crash-involved drivers were less
likely to check their truck each day for defects
- behaviours and attitudes relating
to speed judgement, behaviour of other road users, drug
taking and use of alcohol were similar for crash- and
non-crash-involved drivers
- although estimated stopping
distances were nearer the ideal than in-service
measurements, drivers appreciated the non-linear
relationship between speed and stopping distance
- about a quarter of the drivers took
pills to stay awake
- about 40% of drivers drank after
work several days per week and nearly half of the drivers
drank more than five standard drinks per session
- sleep apnoea appears no more
prevalent in semitrailer drivers than in control
populations but may be higher in drivers who have had
single vehicle crashes
In regard to communication with drivers
and proposals for training, the study concluded:
- ill-feeling towards some of the
operations of VIC ROADS means that information relating
to sensitive areas may only be successfully collected
from truck drivers by independent organisations or
intermediaries
- drivers perceive themselves as
skilled professionals with only a minority of
"cowboys". Acknowledgment of their skills and
appealing to their professionalism may be a successful
technique in communicating with drivers
- drivers most often wanted to be
better at keeping calm when held up on the road, despite
not nominating this as one of the most important
abilities
- drivers felt that training car
drivers not to cut in on trucks and requiring endorsed
licences for towing caravans were training programmes
necessary for other road users.
