① Strengthen lift axle installation requirements for trucks/special-purpose vehicles <Type: Tightening>
- Article 13

② Reflective tape installation requirements for trucks/special-purpose vehicles <Type: Establishment>

- Article 49, attached Table 32-2

 ③ Strengthen brake system installation requirements for two-wheeled vehicles <Type: Tightening>
- Article 67

④ Adjust requirements for high-voltage electric devices and head-on/side impact tests <Type: Tightening>

(1) Reasons for Proposal

The Amendment aims to improve upon lift axle installation requirements to prevent major traffic accidents caused by the overloading of trucks, etc. To reduce casualties in motor vehicle collisions, the Amendment introduces requirements for partial head-on impact and pole side impact while aligning with international standards for such provisions as reflective tape installation requirements for trucks to prevent night time collisions, and brake system requirements for two-wheeled motor vehicles, thereby aiming to close the loopholes of the current system.

(2) Major Provisions

A. Relax ground clearance requirements and diversify the materials, etc. of storage compartment/window glass (Article 4, Article 5, Article 32, Article 34, Article 37, attached Table 33)

Improve upon the design and performance of motor vehicles by relaxing ground clearance requirements to match speed bump requirements for domestic roads; diversifying materials used for storage compartments; and improving requirements for the opening direction of exhaust pipes.

B. Improve lift axle installation requirements and introduce reflective tape installation requirements (Article 13, Article 49, attached Table 32-2)

Prevent major traffic accidents caused by the overloading of trucks, etc., by prescribing that the lift axle shall detect the load on the axle and be automatically raised; and prevent nighttime collisions of trucks by introducing reflective tape installation requirements that match international standards.

C. Modifying requirements for engine output error and braking systems for two-wheeled motor vehicles (Article 63-2, Article 67, attached Table 5-13)

Clearly distinguish between internal combustion engines and drive motors as for engines of two-wheeled motor vehicles and modify the respective output error bounds in accordance with the self-authentication system.

Ensure safety and align combined braking systems with international standards by prescribing compulsory installation of anti-lock braking systems (ABS) for two-wheeled motor vehicles.

D. Align impact requirements with international standards (Articles 89, 91, 92, and 102; attached Tables 11-3, 11-5, 14, and 14-2)

Reduce damage caused by motor vehicle collisions and address commercial issues arising from the trading of motor vehicles by introducing the requirements for partial head-on impact and pole side impact and otherwise aligning motor vehicle impact requirements with international standards.
