Die Technikfragen vom Prüfer 😱 | Fahrzeugtechnik erklärt! Tipps für die Fahrprüfung Klasse B 🚗🛠️📋

Summary

In this video, Tom from the Driving School Academy guides viewers through the essential technical checks before a practical Class B driving test. He emphasizes key areas like tire inspection, headlights, steering play, brake system checks, fluid levels, and emergency kits. Tom explains how to check components such as tread depth, tire pressure, brake resistance, and various lights, including rear fog and high beams. He offers tips for answering examiner questions, discusses the importance of the first impression, and provides advice on how to ensure the car is test-ready. Tom concludes by wishing viewers success in their driving tests.

Takeaways

• 😀 You can't fail the technical part alone during a driving test, but it still plays an important role in the overall evaluation.
• 😀 First impressions matter, so pay attention to the details during the test to avoid any errors.
• 😀 The examiner will typically check the headlights, tires, fluid levels, steering, braking system, and emergency kit, among other things.
• 😀 When inspecting tires, check the tread depth and ensure it's above 1.6mm. Use the TWII marking or bulge indicator for depth validation.
• 😀 Tire pressure should be checked according to the car's load. Refer to the sticker on the B-pillar or owner's manual for correct tire pressure.
• 😀 Headlights must be clean, functional, and free from damage. Make sure to check both low and high beams, along with the fog lights.
• 😀 The rear fog light should only be used in foggy conditions with visibility under 50 meters, not in rain or snow.
• 😀 During the steering play check, ensure the steering wheel moves slightly before the tires. The maximum play allowed is about 2 cm (or two fingers).
• 😀 For brake checks, ensure there's resistance in the brake pedal. The pedal shouldn't go all the way down, indicating proper hydraulic function.
• 😀 Always check the fluid levels, including windshield washer fluid, coolant, brake fluid, and oil, ensuring they’re within the recommended levels.
• 😀 The emergency kit should be in the car, including a first aid kit, warning triangle, and Tüff certificate. The examiner may ask about it during the test.

Q & A

What is the purpose of the technical part of the driving test?

The technical part of the driving test serves as an error assessment, not a separate pass/fail section. It helps assess whether the car is safe and ready for driving, ensuring that key vehicle systems are functioning correctly before the practical test begins.

What are the basic things that the examiner checks during the technical part of the test?

The examiner typically checks the headlights, tires, fluid levels, steering, braking system, and sometimes the emergency kit. These checks ensure that the car is in safe working order.

What is the legal minimum tread depth required for tires during the driving test?

The legal minimum tread depth for tires is 1.6 mm, but it’s better to have a tread depth above this value for optimal safety and performance.

How can you check the tread depth of a tire without special tools?

You can check the tread depth by looking for a marking, such as the 'TWII' symbol, which indicates the minimum tread depth. A bulge in the tire indicates 1.6 mm of tread depth, which is the legal requirement.

What are the correct tire pressures for a car with standard and full load?

For a car with standard load, the tire pressure should be 2.5 bar at the front and rear. When the car is fully loaded, it should be 2.7 bar at the front and 3.0 bar at the rear. These values can usually be found on a sticker inside the car or in the owner's manual.

What is the proper procedure for checking headlights during the test?

To check the headlights, ensure they are clean, functional, and free of any damage. You can test the light functions by turning on the ignition and manually activating the low beam, high beam, and fog lights. Additionally, you must ensure that the rear fog light is only used in foggy conditions with visibility less than 50 meters.

When is it appropriate to use the rear fog light during the driving test?

The rear fog light should only be used in conditions of heavy fog or poor visibility (less than 50 meters). It should not be used in rain or snow.

What is the importance of checking the steering play during the technical part of the test?

Checking the steering play ensures that there is no excessive dead zone in the steering wheel where movement does not translate to tire movement. This dead zone should not exceed 2 cm (about two fingers' width). This ensures that the car's steering system is responsive and safe to drive.

How do you test the brake system in the car during the driving test?

To test the brake system, press the brake pedal and check for resistance. After pressing the pedal about a third of the way, you should feel noticeable resistance, and the pedal should not move further after two-thirds of the way down. If the pedal moves to the floor, it indicates a problem with the brakes.

How do you check the fluid levels under the bonnet during the driving test?

You check fluid levels by opening the bonnet and inspecting various reservoirs. For example, check the windshield washer fluid, coolant, brake fluid, and engine oil levels. Always ensure the car is level, and the engine has been off for at least five minutes before checking the oil level.

What are the key components included in the emergency kit for the driving test?

The emergency kit typically includes a first aid kit, a warning triangle, and may also include other items like a flashlight, spare tire, and gloves. The examiner may ask to see these items, so it's important to be aware of their location and condition.
