Welcome to the essential unit on passenger vehicle construction, controls, and pre-trip inspections for your Swiss Category D licence. Understanding the mechanics of your bus and performing thorough daily checks are fundamental to ensuring passenger safety and operational reliability. This unit will equip you with the knowledge to identify key components, operate the driver's cockpit effectively, and conduct systematic inspections, preparing you thoroughly for the theory exam and your professional duties.
Browse all lessons that make up Passenger Vehicle Construction, Controls, and Pre-Trip Inspections. 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.
This lesson provides a foundational overview of a passenger vehicle's main components. You will learn to identify and understand the function of the engine, transmission, suspension, and electrical systems. This knowledge is essential for effective pre-trip checks and for communicating with maintenance staff about potential vehicle issues.
This lesson provides a detailed tour of the driver's area in a typical bus or coach. You will learn the function of every switch, lever, and button, from the main driving controls to secondary systems like heating and door operation. Interpreting the instrument panel and responding correctly to warning lights is a key focus.
Large passenger vehicles rely on powerful air brake systems. This lesson explains how these systems work, including the importance of monitoring air pressure. It also details the function and proper use of auxiliary braking systems (retarders) to control speed on long descents and reduce wear on the service brakes.
A daily walk-around check is a legal requirement and a critical safety routine. This lesson teaches a logical sequence for inspecting the exterior and interior of the bus. You will learn what to look for, from fluid leaks and body damage to the condition of passenger areas, ensuring the vehicle is safe before starting service.
The condition of tyres and wheels is paramount to safety. This lesson details how to check tyre pressures, tread depth, and sidewalls for any damage or defects. You will also learn to inspect wheel nuts for security and look for signs of issues with the suspension system.
Being seen and being able to see are critical for safety. This lesson covers the systematic check of all exterior lights, including headlights, brake lights, and indicators. It also emphasizes the importance of ensuring all mirrors and camera lenses are clean, undamaged, and properly adjusted for maximum visibility.
This lesson focuses on the legally required safety equipment that must be on board every passenger vehicle. You will learn how to locate and check the fire extinguisher, first aid kit, and emergency hammers. It also covers the inspection of emergency exits to ensure they are unobstructed and functional.

Pre-trip inspections are critical in Switzerland for professional drivers as they are a legal requirement and a key part of the duty of care owed to passengers. They ensure the vehicle is safe to operate, preventing potential accidents caused by mechanical failure. This diligence also contributes to the reliability of public transport services and upholds professional standards.
During a daily walk-around, you should systematically check tyres (pressure, tread depth, damage), wheels, suspension, lights (headlights, indicators, brake lights), mirrors, windscreen, wipers, fluid levels (oil, coolant, brake fluid), and look for any leaks or damage to the bodywork. Also, verify that essential emergency equipment is present and accessible.
Air brakes use compressed air to apply braking force. You should check for air leaks and ensure the air pressure builds up correctly before driving. While you won't perform a mechanical service, understanding the system helps you recognise potential issues, like a slow pressure build-up or warning lights, which must be reported.
If you discover a defect, especially one that compromises safety, you must report it immediately to your supervisor or the designated maintenance personnel. Depending on the severity, the vehicle may be deemed unfit for service until the issue is resolved. Never operate a vehicle with a known safety defect.
Yes, Swiss regulations require specific emergency equipment to be carried and maintained. This typically includes a fire extinguisher, first aid kit, and warning triangle. You must ensure these items are present, correctly located, easily accessible, and within their expiry dates (for extinguishers and some medical supplies).
A retarder is an auxiliary braking system designed to slow the vehicle without using the main service brakes, which are typically air brakes on buses. Retarders reduce wear on the service brakes and are particularly useful for managing speed on long descents, helping to prevent brake fade. Understanding its operation is key for smooth and safe driving, especially in mountainous Swiss terrain.
