Stress is an integral part of our lives. Even if we learn to manage and cope with it, its effects persist, influencing our behaviour and therefore our safety. Long overlooked, stress is a real risk factor when driving. Driver training is therefore not just about teaching rules or trajectories: it is also about preparing drivers to keep their cool, even under pressure.
Stress while driving: what are we talking about?
By definition, stress is a physiological and psychological reaction to adapt to a situation perceived as restrictive or threatening. It is not, in itself, a negative phenomenon. A certain level of stress can keep you alert, stimulate your reaction times or enable you to better manage the unexpected, as is the case when driving.
But beyond a certain threshold, stress becomes a hindrance. It disrupts concentration, impairs judgement and sometimes causes aggressive behaviour.
In the context of driving, a distinction is generally made between:
- Acute stress linked to an immediate situation: a traffic jam, rude behaviour, emergency braking, bad weather, etc.
- Chronic stress caused by stressful daily commutes, tight schedules, fatigue, or mental overload.
Both can impair the driving quality of novice drivers as well as experienced drivers.
A real impact on behaviour... and risks
Stress affects driving behaviour. It does not just cause irritation or fatigue: it changes behaviour. When under stress, drivers:
- perceives important information less well (narrower vision, less peripheral vision),
- reacts more slowly to a danger (slower reaction time),
- makes more impulsive or hesitant decisions,
- often displays more aggressive behaviour (sudden acceleration, risky overtaking, reduced following distance, etc.).
Another finding is that stress does not spare experienced drivers. Professional drivers, delivery drivers, bus drivers and lorry drivers are under dual pressure: that of traffic and that of meeting targets. The result is accumulated fatigue, constant nervous tension and an increase in risky behaviour.
Teaching people to drive also means teaching them how to manage stress
At Develter Innovation, we don’t train ‘perfect’ drivers. We train drivers who can adapt to the realities of the road. In this reality, stress is ever-present.
That is why our simulators incorporate scenarios that replicate the most common stressful situations encountered whilst driving:
- Making quick decisions in unpredictable traffic,
- Faire face à des incertitudes ou à des événements perturbateurs,
- Operating in a hazardous environment.
Our aim is to help drivers learn to stay in control of their driving, even under pressure. By analysing reactions, replaying scenarios and identifying subtle cues (changes in trajectory, averting one’s gaze, micro-errors), we can help drivers improve their behaviour without stigmatising them.
Training courses that incorporate these aspects go beyond mere technical skills. They help learners to recognise the early signs of tension, to adopt simple coping strategies (taking a break, breathing, maintaining a safe distance, etc.), and, above all, to understand that a good driver is not someone who never feels stress, but someone who knows how to manage it.
