Risk understanding in traffic

Driving a car always involves a certain risk. Good drivers stand out because they understand how risk arises and actively work to reduce it. In the class B theory test, you will be tested precisely on this.

What is risk in traffic?

Risk is the probability that something dangerous will happen, combined with the severity of the consequences. Two factors determine the level of risk:

To reduce risk, you need to influence both factors. Lower speed reduces both the probability of an accident and the severity if it occurs.

Risk acceptance and risk assessment

Many drivers accept higher risk than necessary because they overestimate their own skills or underestimate the conditions. Typical pitfalls include:

• Driving too fast because the road seems clear
• Relying on other road users to do the right thing
• Taking chances in overtaking situations
• Underestimating the effects of fatigue and reduced concentration

A good driver has low risk acceptance and always accounts for the unexpected.

Hazard picture and hidden dangers

Hidden dangers are situations where the risk is not immediately visible. A child behind a parked car, a cyclist in the blind spot, or ice under a thin layer of water are examples. You should always adjust your speed to hidden dangers and keep a large enough distance to be able to stop.

How to reduce risk

• Adjust your speed to road, weather, and traffic conditions
• Keep a good distance from the vehicle in front
• Always use a seatbelt
• Avoid distractions like mobile phones
• Drive defensively and anticipate others’ mistakes
