This critical final unit equips you to manage high-risk situations on Swiss roads. We cover the profound dangers of fatigue and impairing substances, and provide essential protocols for mechanical breakdowns, tyre failures, fires, and acting as first responder at an accident scene. Mastering these emergency procedures is vital for your C/C1 licence theory exam and ensuring safety in professional driving.

Browse all lessons that make up Fatigue, Legal Consequences, Breakdowns, Fire, Load Incidents and Emergencies. 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.
Fatigue is a major cause of accidents in the transport industry. This lesson teaches drivers to identify the early warning signs of tiredness, such as frequent yawning, heavy eyelids, and difficulty concentrating. It emphasizes that the only effective cure for fatigue is sleep and reinforces the legal and personal responsibility to take required breaks and never drive while tired.
For professional drivers, the rules regarding intoxicating substances are extremely strict. This lesson explains the severe effects of alcohol and illegal drugs on driving ability and the serious legal consequences of being caught under their influence. It also highlights the importance of checking with a doctor or pharmacist whether any prescribed or over-the-counter medication can cause drowsiness or otherwise impair driving.
A tyre blowout or engine failure can be a frightening experience. This lesson provides a clear action plan: maintain a firm grip on the steering wheel, avoid harsh braking, signal, and move the vehicle to a safe location like the hard shoulder if possible. It then covers the essential safety steps of activating hazard lights, placing the warning triangle, and waiting in a safe place away from the vehicle.
After stopping for an emergency, making the scene safe is the top priority. This lesson details the procedure: activate hazard warning lights, put on high-visibility clothing before exiting the cab, and place the warning triangle at the correct distance behind the vehicle (at least 100m on motorways). This warns approaching traffic and creates a safer environment for the driver and emergency responders.
Vehicle fires can start from overheated brakes, tyres, or electrical faults. This lesson covers preventative checks and the immediate actions to take if a fire is detected: stop safely, shut off the engine, and call the emergency services. It provides guidance on using the on-board fire extinguisher for small, accessible fires but stresses that personal safety is paramount and the driver should not take unreasonable risks.
Losing part of a load on the road creates an immediate and serious hazard for other drivers. This lesson outlines the driver's responsibilities: stop in a safe place, assess the situation from a safe distance, and immediately alert the police. The driver's primary role is to warn other road users and not to attempt to retrieve the load from a live carriageway.
This lesson provides a structured guide for managing the scene of a road traffic accident. It covers the internationally recognized priorities: assess for danger, make the scene safe, send for help by calling emergency services (112), and provide first aid to the injured if trained to do so. It also details the legal requirement to stop and exchange information after being involved in a collision.

On a Swiss motorway, your first priority is safety. Activate your hazard lights immediately. If possible, steer your vehicle onto the hard shoulder or emergency lane, as far to the right as possible. Put on your high-visibility vest before exiting the vehicle, and ensure all passengers do the same. Exit the vehicle from the side furthest from traffic and stand behind the safety barrier, well away from the roadway. Place your warning triangle at the prescribed distance behind your vehicle (usually 100m on motorways) and call emergency services or breakdown assistance.
Driver fatigue significantly impairs judgment, reaction time, and concentration, which are crucial for operating large, heavy vehicles. In Switzerland, for HGVs (Category C/C1), fatigue increases the risk of severe accidents, especially on challenging terrain or during long-distance driving. Swiss law strictly regulates driving and rest times using tachographs to prevent fatigue-related incidents. Failing to adhere to these regulations can lead to serious legal consequences, including hefty fines and licence suspension.
If you suspect a fire, activate your hazard lights and find a safe place to stop immediately, away from traffic and potential fuel sources. Turn off the engine and evacuate the vehicle swiftly, ensuring all occupants are safely clear. Do not attempt to fight a fire yourself unless it is very small and you have the correct fire extinguisher and training. Call the emergency services immediately and inform them of your location and the situation.
As the first on the scene, your primary duty is to secure the area and provide assistance. Ensure your vehicle's hazard lights are on and, if safe, place your warning triangle. Check for injuries and administer first aid if trained. Call emergency services (112 or 117 for police, 144 for ambulance) and provide clear details about the location, number of vehicles involved, and any injuries. Do not move injured persons unless there is immediate danger. Preserve evidence if possible, but prioritize safety and assisting the injured.
Both require stopping safely, but a tyre failure, especially a blowout, can be sudden and dramatic, potentially causing loss of control. A mechanical breakdown might be more gradual. For both, the immediate steps are similar: activate hazard lights, pull over safely, wear high-visibility clothing, exit the vehicle safely away from traffic, and set up the warning triangle. However, the diagnosis and repair approach will differ, with tyre issues often requiring a specific tyre service, while mechanical problems may need a general breakdown service.
Yes, a load can shift even during normal driving due to acceleration, braking, cornering, and vibrations, especially if not properly secured. A shifting load can drastically alter the vehicle's centre of gravity, leading to instability, reduced steering control, and increased braking distances. In severe cases, it can cause rollovers or cargo spillage, creating significant hazards for other road users and leading to legal penalties for the driver.
