distraction was a contributing factor, is higher in <strong>young</strong> <strong>drivers</strong> than in older,<br />

more experienced <strong>drivers</strong>. If <strong>young</strong> <strong>drivers</strong> are more involved in crashes than<br />

middle-aged <strong>drivers</strong> due to strong emotions (e.g. anger), is not clear.<br />

Young <strong>novice</strong> <strong>drivers</strong> are also overrepresented in crashes because they<br />

chose to drive in circumstances that are more demanding for all <strong>drivers</strong>.<br />

Except for the <strong>young</strong>est group <strong>of</strong> <strong>novice</strong> <strong>drivers</strong> (18 and 19 years <strong>of</strong> age in the<br />

Netherlands), <strong>young</strong> <strong>novice</strong> <strong>drivers</strong> tend to drive too fast. Although the<br />

<strong>young</strong>est <strong>novice</strong> <strong>drivers</strong> speed less <strong>of</strong>ten than older <strong>novice</strong> <strong>drivers</strong> do, they<br />

do drive too fast for the circumstances (e.g. driving too fast in a curve).<br />

Young <strong>novice</strong> <strong>drivers</strong> more <strong>of</strong>ten also drive late at night and they more <strong>of</strong>ten<br />

drive with passengers that might distract them. Crash involvement is higher<br />

and the crashes are more severe because <strong>young</strong> <strong>novice</strong> <strong>drivers</strong> more <strong>of</strong>ten<br />

drive in older cars with less active and passive safety features.<br />

Chapter 3 provides the theoretical background for the empirical studies in<br />

this thesis. <strong>Hazard</strong> <strong>anticipation</strong> is described as including processes related to:<br />

• Detection and recognition <strong>of</strong> potential dangerous road and traffic<br />

situations;<br />

• Prediction about how these latent hazards may develop into acute<br />

threats;<br />

• Feelings <strong>of</strong> risk that are evoked by these predictions;<br />

• Selection and execution <strong>of</strong> actions that will reduce these feelings <strong>of</strong> risks<br />

and will ensure a safety margin that is large enough to avert a crash<br />

should the latent hazard materialize.<br />

<strong>Hazard</strong> <strong>anticipation</strong> has a cognitive aspect (detection recognition and<br />

prediction) and hazard <strong>anticipation</strong> has an emotional and motivational<br />

aspect (feelings <strong>of</strong> risk and the willingness to reduce these feelings <strong>of</strong> risk).<br />

Various types <strong>of</strong> latent hazards are distinguished. The two types that are<br />

investigated in this thesis are covert latent hazards and overt latent hazards.<br />

Covert latent hazards are possible other road users on collision course that<br />

are hidden from view. A for the driver possible but yet invisible child that<br />

may cross the road from between parked cars is an example <strong>of</strong> a covert latent<br />

hazard. Overt latent hazards are visible other road users that due to the<br />

evolving circumstances may start to act dangerously. A pedestrian that may<br />

suddenly cross the road in order to catch his bus, is an example <strong>of</strong> an overt<br />

latent hazard. The processes involved in hazard <strong>anticipation</strong> can be executed<br />

automatically without much conscious awareness and these processes can be<br />

executed in a controlled manner. To illustrate how this may function the<br />
