1. Overview of the Bus
a. What is a Bus?
A bus, commonly referred to simply as a “bus,” is a public transportation vehicle designed to carry a large number of passengers along fixed routes. Buses are usually large in size, capable of transporting many passengers, and are widely used in cities and urban areas worldwide.
Buses can vary in size, design, and function depending on the specific operational needs of each locality. However, some common characteristics of buses include:
- Passenger seating: Buses typically have a large number of seats for passengers. There may be standing or reclining areas depending on the specific design of each bus type.
- Entry and exit doors: Buses usually have multiple doors allowing passengers to board and alight easily from various sides of the vehicle. Doors can be automatic or manually operated.
- Payment system: To use the bus service, passengers typically pay a fare or use smart cards or cash cards to pay for tickets.
- Fixed routes: Buses operate on fixed routes with designated stops. Usually, there is a fixed schedule for each route so passengers can know the expected bus arrival times.
- Operational management: Bus services are generally managed by public transport authorities or companies and must comply with traffic safety regulations and service quality standards.
In some cases, buses may be adapted to meet specific needs such as extended-route buses for long-distance travel, highway buses, or buses powered by renewable energy to minimize environmental impact.
b. Operating Principle of the Bus
- Engine:
- In most cases, buses use internal combustion engines (diesel engines) or electric motors.
- Diesel engine: The bus gains power from a conventional diesel engine, running on diesel fuel. The fuel is burned in the combustion chamber to generate mechanical energy.
- Electric motor: Electric buses use electric motors to generate power. Energy is supplied from batteries or external power sources, and the motor drives the wheels through a transmission system.
- Transmission system:
- In buses with internal combustion engines, energy from the engine is transmitted to the wheels through a transmission system, including the gearbox, driveshaft, and sometimes a transfer case.
- In electric buses, the electric motor directly supplies power to the wheels through a transmission system, often a screw drive or electronic drive system.
- Steering and braking systems:
- The steering system of the bus is similar to that of other vehicles, allowing the driver to control the direction of travel.
- The braking system includes mechanical brakes or electric brakes, depending on the bus type. Mechanical brakes use friction between the wheels and disc or drum brakes to reduce speed, while electric brakes use regenerative braking to convert kinetic energy into electrical energy stored in batteries or power systems for later use.
- Suspension and chassis systems:
- The suspension system helps reduce shocks and allows the bus to travel smoothly on uneven road surfaces.
- The chassis system includes components such as tires, frame, and other parts that support the vehicle’s weight and enhance stability.
c. The Role of Buses in Urban Transportation Development
Buses play an important role in the development of urban transportation and affect many aspects of city life. Below are some key roles of buses:
- Primary form of public transportation:
- Buses are a key part of official public transportation systems in major cities. They provide easy and convenient mobility for urban residents, helping to reduce personal vehicle use and lower environmental pollution.
- Saving urban space:
- Compared to personal cars, using buses helps reduce air pollution and parking pressure in urban areas. One bus can carry many passengers, saving space compared to many individual cars.
- Convenience and cost savings for residents:
- Buses provide a safe, convenient, and affordable public transport option for urban residents. Compared to owning and maintaining a car, taking the bus often saves costs, especially for people who do not need to use a car daily.
- Reducing traffic congestion and pollution:
- Buses help reduce congestion and pollution by lowering the number of personal vehicles on the streets. When more people choose buses over cars, fewer vehicles are on the road, helping ease traffic jams and reduce emissions from private vehicles.
- Supporting transportation infrastructure:
- Using buses can help reduce the load on transportation infrastructure, maintenance of roads, bridges, and tunnels. This helps keep urban transport infrastructure maintained and functioning more efficiently.
2. Overview of Safety Training for Bus Operation
a. What is Occupational Safety Training?
- Occupational safety training for bus operation consists of sessions that provide workers with awareness of how to prevent workplace accidents. Workers directly involved with bus operation belong to Group 3.
- The safety training course helps workers recognize and avoid hazards, reducing the risk of occupational accidents during work.

b. Training Duration
Initial safety training duration:
- Total training time is at least 24 hours, including exam time.
- 8 hours of theory on policies and laws related to occupational safety and hygiene.
- 8 hours of theory on basic knowledge of occupational safety and hygiene.
- 4 hours of theory on specialized training content.
- 2 hours of practical training on specialized content.
- 2 hours of theory exam at the end of the course.
The safety training center will arrange the schedule in multiple sessions depending on workers’ availability. Typically, there are 6 sessions held over 3 days, provided the company arranges continuous learning time.
Periodic safety training duration:
- Before the occupational safety card expires, workers must undergo periodic safety training lasting at least 50% of the initial safety training duration to renew their card.
Explanation: The total time for periodic occupational safety training is at least 12 hours, including exam time. After completing the periodic training and passing the exam, workers will have their occupational safety cards reissued or extended.

d. Occupational Safety Card
After completing the occupational safety training course and passing the exam, workers will be issued an occupational safety card (commonly called the occupational safety certificate for Group 3).
The Group 3 safety card clearly displays information such as full name, date of birth, specific job and work environment. It also includes training duration, an official red stamp, and a signature confirming course completion.
According to regulations on issuing safety cards stated in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:
- If the employer and employee have a labor contract, the employer must sign, stamp, and endorse the safety card for Group 3 workers after they complete training from an occupational safety training unit and pass the exam.
- If the worker is freelance, seasonal, or does not have a labor contract, the training unit must sign, stamp, and endorse the safety card after the worker completes training and passes the exam from the occupational safety training unit.
