Munich (ots) - Leaving the lane is the most common cause of accidents at almost 40 percent that is registered in the ADAC accident database. ADAC Accident Research evaluates data from accidents that mostly occur outside of town, because ADAC air rescue can only be deployed there. Most of the time, such accidents happen due to inattentiveness on the part of the driver, often on a straight road.

These mostly serious accidents can be prevented by using lane assistants. In an evaluation of the Euro NCAP tests from 2018 and 2019, the ADAC determined what the lane departure warning systems of a total of 71 car models can and cannot do.

At the very top of the ranking, the Model 3 and Model X from Tesla and the Audi Q3 landed tied in the first three places. Your lane assistants contain all useful functionalities - from automatic activation when you restart, to recognizing the edge of the road, even without marking, to protecting against collision with oncoming traffic. At the bottom of the list are the Suzuki Jimny, which only has a lane departure warning, as well as the Fiat Panda and the Wrangler Jeep, which do not have a lane assistant.

The vehicle manufacturers have installed different types of lane assistants in their cars. Some systems guide the vehicle in the middle of the lane, but also intervene permanently in the lane guidance. According to ADAC, systems that indicate whether the car recognizes the lane boundary and only intervene gently if there is a risk of the lane boundary being crossed make the most sense. As long as the vehicle remains largely in the middle of the lane, there is no steering intervention. Emergency lane departure warning systems, on the other hand, intervene more courageously, but only when the situation threatens to become critical.

Lane assistants have great potential to prevent accidents - provided they are activated and working properly. The systems are quickly found to be disruptive if the driver does not understand how they work. It is therefore crucial that the driver familiarizes himself with how his vehicle assistants work so that they can also develop their potential.

The Euro NCAP tests show that sophisticated assistants are already available today. From 2022 their use will be mandatory in new vehicle models, from 2024 in all newly registered cars and light trucks up to 3,5 tons. According to ADAC, however, it is crucial that the systems are activated automatically when the vehicle is started and not remain switched off after manual deactivation. According to the ADAC, from 2022/2024 it should also be mandatory that lane assistants recognize the edge of the road, even if there are no lane markings. Since there are no markings on many narrow and dangerous overland routes, such a system would have great potential for preventing accidents.
