How are we affected by stress in traffic?

We need a certain dose of stress to stay alert and to be able to concentrate and make good decisions in traffic. However, too much stress is a major risk factor among drivers, which can then lead to impaired driving ability. It is important to find a balance that keeps us alert in traffic, without it negatively affecting our driving ability.

High stress can, among other things, lead to more aggressive driving, as well as that drivers become worse at, for example, scanning, and can react inappropriately to situations that arise in traffic.
