Vehicle Knowledge
Understand how your vehicle works — from tyres and brakes to safety systems and carrying loads.
Vehicle knowledge is about understanding your car — how systems work, what their limits are and how to keep the vehicle in good technical condition. A well-maintained car is not only more reliable but also safer and more economical.
Tyres are the only contact point between your car and the road. A minimum tread depth of 1.6 mm is legally required, but experts recommend 2-3 mm for wet conditions. Tyre pressure directly affects road holding, fuel consumption and wear — check monthly with cold tyres.
The braking system is crucial for safety. Modern cars have ABS, which prevents the wheels from locking during an emergency stop and keeps the steering functional. During an emergency stop press the brake fully — pumping is not necessary with ABS and is even counterproductive. Brake fluid absorbs moisture and must be replaced every two years.
The APK (General Periodic Inspection) checks whether your vehicle is technically sound. New cars undergo their first APK after four years, then annually. Driving without a valid APK certificate is a criminal offence and may invalidate your insurance.

Frequently asked questions
What is the minimum tread depth for passenger car tyres?
The legal minimum tread depth is 1.6 mm. Below this depth the tyre can no longer effectively displace water, which greatly increases the risk of aquaplaning and skidding. Experts recommend a minimum of 2-3 mm.
How do I use ABS correctly during an emergency stop?
During an emergency stop with ABS press the brake fully and keep it pressed. Pumping is not necessary — ABS does this automatically. Pumping actually reduces braking effectiveness.
When does my car need its APK?
New passenger cars go for their first APK after 4 years. After that the APK is mandatory every year. Driving without a valid APK certificate is a criminal offence and may invalidate your liability insurance.
Can a rear-facing child seat be placed in front of an airbag?
No. A rear-facing child seat must never be placed on a seat with an active front airbag. The force of the airbag can cause fatal injuries to the child. Deactivate the airbag or place the seat on the back seat.
