Lorry drivers on the road experience pleasant as well as unpleasant aspects of their job. They usually find their job pleasant, but the special measures aimed at lorries are sometimes found unpleasant or even irritating. This questionnaire study of lorry drivers deals with whether these emotions have consequences for safe and unsafe behaviour. The study is divided into three parts. The first part studied if there are traffic situations involving the overtaking prohibition and the speed limiter for lorries. 85 lorry drivers were asked how frequently they encounter these situations and how `annoying' they find them. The second part studied how (especially negative) emotions developed in six of these situations, and what the consequences were for behaviour and safety. This was done by confronting 206 lorry drivers with statements. The third part studied the more general aspect of the `emotional housekeeping': which moods and emotions are generally present before and during driving, and how they relate to (un)safety. All lorry drivers were asked questions about age, experience, type of transport, distances covered, offences, fines, near-accidents, and accidents.
