2.5.2.4. "Additional steering equipment" means a system, independent of the main steering system, by which the steering angle of one or more axle(s) of the steering system can be influenced selectively for manoeuvring purposes.
2.5.2.5. "Full-power steering equipment" means equipment in which the steering forces are provided solely by one or more energy supplies.
2.5.3. Depending on the arrangement of the steered wheels, the following types of steering equipment are distinguished:
2.5.3.1. "Front-wheel steering equipment" in which only the wheels of the front axle(s) are steered. This includes all wheels which are steered in the same direction;
2.5.3.2. "Rear-wheel steering equipment" in which only the wheels of the rear axle(s) are steered. This includes all wheels which are steered in the same direction;
2.5.3.3. "Multi-wheel steering equipment" in which the wheels of one or more of each of the front and the rear axle(s) are steered;
2.5.3.3.1. "All-wheel steering equipment" in which all the wheels are steered;
2.5.3.3.2. "Buckle steering equipment" in which the movement of chassis parts relative to each other is directly produced by the steering forces.
2.6. Types of steering transmission
 Depending on the way the steering forces are transmitted, the following types of steering transmission are distinguished:
2.6.1. "Purely mechanical steering transmission" means a steering transmission in which the steering forces are transmitted entirely by mechanical means;
2.6.2. "Purely hydraulic steering transmission" means a steering transmission in which the steering forces, somewhere in the transmission, are transmitted only by hydraulic means;
2.6.3. "Purely electric steering transmission" means a steering transmission in which the steering forces, somewhere in the transmission, are transmitted only through electric means;
2.6.4. "Hybrid steering transmission" means a steering transmission in which part of the steering forces is transmitted through one and the other part through another of the above mentioned means. However, in the case where any mechanical part of the transmission is designed only to give position feedback and is too weak to transmit the total sum of the steering forces, this system shall be considered to be purely hydraulic or purely electric steering transmission.
2.7. "Electric control line" means the electrical connection which provides the steering control function to the trailer. It comprises the electrical wiring and connector and includes the parts for data communication and the electrical energy supply for the trailer control transmission.
3.  Application for approval
3.1. The application for approval of a vehicle type with regard to the steering equipment shall be submitted by the vehicle manufacturer or by his duly accredited representative.
3.2. It shall be accompanied by the undermentioned documents in triplicate, and by the following particulars:
3.2.1. A description of the vehicle type with regard to the items mentioned in paragraph 2.2.;
