control
People underestimate the likelihood of bad
outcomes and overestimate the likelihood of
good outcomes for themselves compared to
others.
This tendency is strengthened for outcomes
perceived as controllable by the person.
Examples:
- Newlyweds expect their marriage to last a lifetime, even while
aware of the divorce statistics.
- Smokers believe they are less at risk of developing smoking-related
diseases than others who smoke.
- Car drivers estimate their chances of an accident when driving
under the influence of alcohol as lower than for drunken driving in
general.
6. Risk perception in driving (Fuller, 2005)
Gudela Grote
Page6
Felt risk mirrors task difficulty.
Task difficulty is determined by task demands
and individual capability.
Estimated statistical risk and felt risk regarding
speed only coincide at higher speeds where
task demands approach individual capability
(= task difficulty is very high).
7. Risk as benefit: Risk seeking behavior
Gudela Grote
Page7
Risk seeking versus risk avoidance
- Personality characteristic
- Cultural norm
- Affected by situational characteristics
• gain versus loss
• personal control
8. Different types of driver errors
Gudela Grote
Page8
(Reason et al., 1990)
Lapse
- e.g. attempt to drive away from traffic light in third
gear
Mistake
- e.g. underestimate the speed of oncoming vehicle
when overtaking
Violation
- Unintended: e.g. unknowingly speeding
- Deliberate: e.g. get involved in races with other
drivers
9. Measures to avoid driver errors
Gudela Grote
Page9
Lapse Support vigilance
Mistake Increase training and
experience
Violation
- Unintended Support vigilance
- Deliberate Change individual and collective
behavior norms

11. Leadership to support safe driving
Gudela Grote
Page11
(Newman, Griffin & Mason, 2008)
High safety motivation of drivers is related to few self-
reported crashes.
Drivers' safety motivation is related to their perception
of managers' safety values.
Managers' perception of organizational safety values
are related to drivers' perception of managers' safety
values.
Leadership at all levels of the organization influences
drivers' safety motivation and behavior.
Safety interventions should address the organizational,
work group, and individual level. (Newman & Watson, 2011)
12. General safety management
Gudela Grote
Page12
Safety Policy
Risk identification and mitigation
Safety resources and responsibilities
Standards and procedures
Training
Safety performance monitoring
Continuous improvement
Management of change
13. Example Standards and Procedures: Gudela Grote
Page13
Rules at Shell
Four out of twelve are driving related!
One basic rule about rules: Use fixed prescription
only when it really holds in all situations
14. Specific safety management measures Gudela Grote
Page14
for safe driving
Selection
- avoid hiring young men
- test for risk perception and risk seeking/avoidance
Handling fatigue
- establish a not fit to drive rule
- structure driving schedules to allow for sufficient breaks and
rest time
- take into account commuting time when designing work
schedules more generally
- train drivers to handle monotony while driving
Policy for mobile phone use
- generally avoid phone use
- if unavoidable only use when vehicle is stopped
- if unavoidable during driving ensure proper technical systems
and training
15. Shared norms and values
Gudela Grote
Page15
Establishing shared norms and values that
support safe work processes and behaviors as
defined in the safety management system
Establish a safety culture
Safety culture as part of organizational culture
= shared basic beliefs and assumptions
- safety versus production
- trust versus control
- role of people and technology
Culture often most visible as a source of
resistance to change
16. Supporting organizational and cultural Gudela Grote
Page16
change
Causes of resistance to change
- Sense of loss of control
- Sticking to old norms as part of existing culture
Strategies for dealing with resistance
- Coercive: sanction change through use of power
- Rational: inform about advantages of change
- Normative: develop new values and norms =
culture change
Requirements for normative strategy
- Participation to improve quality and acceptance
of decisions
- Psychological safety
17. An easy start into cultural change ...
Gudela Grote

Having people answer questions like the
following reduces self-reported risky driving
several weeks later (Falk, 2010)
- Take over when the car in front slows down in
adherence to speed limit
- Drive too close to car in front to get driver to move out
of the way
- Drive fast to show others I can handle the car
- It is OK to speed when traffic conditions allow
- If you have good driving skills speeding is OK
- Sometimes it is necessary to bend the rules to keep
traffic going
- I often think about the possibility that I myself might get
hurt in traffic.
- I could not live with myself if I hurt another human
being in traffic.
