This unit focuses on the essential mechanical aspects and safety systems of modern lorries, crucial for Category C and C1 drivers in Switzerland. You'll learn about the vehicle's construction, controls, and your legal responsibility to ensure it is roadworthy through systematic checks and by understanding warning signals. Mastering these basics is vital for both the theory exam and safe operation on Swiss roads.
Browse all lessons that make up Vehicle Construction, Controls, Safety Checks and Roadworthiness. Each lesson focuses on specific topics, learning objectives, and core concepts, helping you build essential knowledge and follow a clear, structured progression toward your study goals in Switzerland.
Understanding the fundamental components of a lorry is essential for any professional driver. This lesson introduces the chassis as the vehicle's main support frame, discusses different cab designs like day cabs and sleeper cabs, and provides an overview of common body types. These include curtain siders for general freight, refrigerated units for temperature-controlled goods, and flatbeds for oversized cargo.
The steering and tyres are two of the most critical safety components of any vehicle. This lesson explains how to perform basic checks on the power steering system and emphasizes the importance of daily tyre inspections. Drivers will learn to check for correct inflation pressure, sufficient tread depth (minimum legal requirements), and any signs of damage like cuts, bulges, or exposed cords on the sidewalls.
The suspension system connects the vehicle's axles to its frame, supporting the massive weight and absorbing shocks from the road surface. This lesson describes the two common types: traditional leaf springs and modern air suspension. It explains how a well-maintained suspension is crucial for vehicle stability, proper handling, braking effectiveness, and preventing damage to the load and the vehicle itself.
Proper visibility is paramount for the safety of large vehicles, especially at night or in poor weather. This lesson covers the full range of required lights, including headlights, indicators, brake lights, and side and rear marker lights. It also explains the function of reflectors and the mandatory high-visibility conspicuity markings that outline the vehicle's shape to other drivers.
Before starting any journey, a professional driver must conduct a thorough pre-drive inspection. This lesson teaches a systematic walk-around method to check critical components like tyres, wheels, lights, mirrors, fluid levels, and safety equipment. This daily routine is a legal requirement and is crucial for identifying potential defects before they become a danger on the road.
The dashboard is the vehicle's primary communication interface with the driver. This lesson explains how to read essential gauges, such as the air pressure gauges for the braking system, the tachometer, and the fuel level. It focuses on recognizing the meaning of different warning lights (red for urgent, amber for caution) and the importance of stopping safely to investigate any critical alerts immediately.
Heavy goods vehicles are fitted with specific safety structures to mitigate the severity of collisions with smaller vehicles and vulnerable road users. This lesson explains the function of the rear underrun bar, which prevents cars from going underneath the truck in a rear-end collision. It also covers side guards, which are designed to stop cyclists and pedestrians from falling under the vehicle's wheels during a side impact.
The driver is legally responsible for the roadworthiness of their vehicle at the start of and during every journey. This lesson outlines the formal process for reporting any identified defects to the transport manager or maintenance staff. It stresses the critical rule that a vehicle with a known safety-critical defect must not be driven until it has been professionally repaired and declared safe.

Find clear answers to the most common questions learners ask about Vehicle Construction, Controls, Safety Checks and Roadworthiness. Understand how the unit is organized, what learning goals it supports, and how it contributes to your study progression with structured explanations and practical guidance tailored for learners in Switzerland.
In Switzerland, professional drivers have a legal responsibility to ensure their heavy goods vehicle is in a roadworthy condition before and during operation. This means conducting regular checks, understanding the vehicle's systems, and immediately reporting any defects that could compromise safety or compliance with traffic laws.
A daily walk-around check involves a systematic inspection of the vehicle's exterior and interior. Key areas include tyres, lights, reflectors, bodywork, underrun protection, fluid levels (oil, coolant, brake fluid), and ensuring all safety equipment is present and functional. You'll also check for any leaks or damage.
Dashboard warning lights are critical indicators of the vehicle's operational status and potential issues. They alert you to problems with systems like the brakes, engine, ABS, or emissions. Understanding what each light signifies and taking appropriate action, such as stopping safely and investigating the fault, is vital for maintaining roadworthiness and preventing further damage.
Driving an unroadworthy vehicle in Switzerland can lead to serious consequences. This includes significant fines, demerit points, suspension of your driving license, and potential criminal charges if an accident occurs due to the vehicle's condition. It also poses a severe risk to yourself and other road users.
While there isn't a single mandated checklist for every vehicle type in Swiss law, the principle of ensuring roadworthiness through diligent pre-drive inspections is a fundamental legal requirement for all professional drivers. Manufacturers often provide recommended procedures, and these, along with general best practices for heavy vehicles, form the basis of compliant inspections.
