Introduction
The national standard “Safety Specifications for Power Driven Vehicles Operating on Roads”
(abbreviated as “GB7258” bellow) is the most basic technical legislation for motor vehicle safety
technical administration in our country, it is also one of the main technical grounds on new vehicle
registrations and regular vehicle inspections, accident investigations etc by the traffic administrations
of the public security organizations. Meanwhile, it is also one of most important technical grounds for
our country’s new vehicle type mandatory ratification tests, new vehicle final production tests and
import motor vehicle inspections.
Since the implementation of GB7258-1997 from 1st January 1998 countrywide, it has made a great
contribution to reinforcing motor vehicle safety administration, raising motor vehicle safety levels and
ensuring road traffic safety. However, accompanying our national economy’s continuous rapid
development, the number of motor vehicles (especially private cars) in our country is increasing rapidly,
4 indexes of the road traffic accidents are rising annually, and the road traffic safety situation is
becoming a major issue. Therefore, based on the technical level of our country’s automobile
manufacturing industry and the reality of continual upgrading of the road grades, in order to raise
motor vehicle technical safety requirements, it is necessary and timely to revise GB7258.
Based on “Road Traffic Safety Regulation of People’s Republic of China” and the real situation on
our country’s motor vehicle safety administration, the main principles in GB7258’s revisions are:
1) Replace the name of “Agricultural Transportation Vehicle” and include it in the “Motor
Vehicle” range for better administration;
2) Increase the passenger car safety requirements adequately. To adapt the current situation of
“motor cars integrating into ordinary families”, allow passenger cars to tow trailers;
3) Increase the safety requirement for large coaches, middle to heavy goods vehicles and high
speed vehicles to increase the road traffic safety;
4) Add basic safety requirement for gaseous vehicles, bi-fuel vehicles and dual fuel vehicles to
enhance the safety administration for these types of vehicles;
5) According to the vehicle situation and the relevant technical development, simplify the
administration levels adequately.
It is necessary to point out:
1) In view of the new technology market development period, it is an international convention to
let the technology mature. To avoid unreasonable technical restriction s to the development of electric
motor vehicles, the revised GB7258 only defines the concept of electric motor vehicles without giving
any specific requirement. During new vehicle registration and the regular vehicle inspection, the
special items for electric motor vehicles can be exempted but any newly manufactured electric motor
vehicle should conform to the present valid relevant standards and requirements.
2) To meet peoples’ ever increasing life quality demands, the revised GB7258 allows passenger
cars to tow trailers but without giving a specific requirement. To guarantee the safety of the passenger
car combination, the relevant organizations of our country should stipulate a technical standard and
administration regulations for passenger car combinations without delay.

GB 7258—200×
3) In view of our country’s motor vehicle gas emission control and noise control standards which are
still being perfected and a series of standards on vehicle gas emissions are being drafted by our country’s
environmental protection departments, the revised GB7258 only gives “motor vehicle’s gas emissions
should conform to the relevant regulations” and “motor vehicle’s outside noise level should conform to
the relevant regulations”, No standard names and dates are quoted. The vehicle manufacturers,
administration organizations and the end users should implement the relevant standards accordingly.
4) The revised GB7258 has not defined the outline size, braking performance, headlight intensity
and luminating position etc for wheeled special engineering vehicles. The manufacturers,
administration organizations and the end users of wheeled special engineering vehicles should
implement the relevant standards accordingly.
5) In view of special shapes and structures, forklift vehicles are not suitable as a type of vehicle
for driving on road, the revised GB7258 does not apply to forklift vehicles. The forklift vehicle
technical requirement should conform to relevant regulations.

braking arms and cam shaft should be parts that do not lose their effectiveness easily. If these parts can become
ineffective, making the vehicles unable to meet the specified emergency braking performance, then they must
be replaced by metals or materials with an equivalent performance to the metals; the braking mechanism
should not have any obvious defects during normal braking.

7.2.4 The braking force for motor vehicles (excluding two wheel, sidecar motorcycles and mopeds) should
be reasonably distributed between the same axle’s two wheels relatively to the vertical central plane of the
vehicle.
7.2.5 The braking system should have a mechanism which compensates for wear. When the braking unit is
wearing out, the braking gap should be easily adjusted through the manual or automatic compensation
mechanism. Any braking controls and their parts and the braking assembly should have a reserve margin.
When the braking devices are overheated or the pads are worn out to a certain degree, effective braking is still
maintained without any immediate adjustment.
7.2.6 For vacuum assisted driving brakes, the specified braking performance should be maintained when the
vacuum assistance unit fails.
7.2.7 The braking pedal travel should conform to the vehicle’s relevant technical specifications.
7.2.8 The force applied on the braking pedal to produce the maximum braking effect should not be higher

semi-trailers excluding the static load transferred to the towing vehicles, when the semi-trailers are under full load and connected
to the towing vehicles,
7.2.12 The braking system’s design and manufacture for motor vehicle combinations should guarantee that
the braking delay between the last axle of the trailer and the front axle of the towing vehicle is less than 0.2 s.
7.3 Emergency Brake
7.3.1 The emergency brake should guarantee that the vehicle can be stopped in the specified distance even

able to initiate the parking brake from his seat. For motor vehicles and wheeled transportation tractor
combinations, when the trailer (excluding trailers with loading below 3000 kg and towed by wheeled tractors)
is not connected to the towing vehicle, the trailer should have its own parking brake. It should be possible for a
man standing on the ground to initiate the trailer’s parking brake.
7.4.2 The parking brake should be able to lock the operating mechanism automatically. The force applied
by the driver’s hand should not be higher than 400 N for passenger cars and 600 N for other vehicles; when
operated by foot, the force should not be higher than 500 N for passenger cars and 700 N for other vehicles.
7.4.3 The parking brake’s control unit should be installed at an appropriate position and have enough travel
margin (excluding those operated by switch). In general the specified braking effect should be reached when
the control unit travels 2/3 of its full travel range. The ratchet control unit should guarantee that when the
specified braking effect is achieved, the control lever’s pulling time is not more than 3.
7.4.4 When a stored spring energy braking system is used for park braking, it should be possible to release
the brake quickly when the system fails; if any special tool is needed, this tool should be included in the tools
which accompany the vehicle.
7.5 For vehicles using an hydraulic braking servo, the brake pedal should not move forward slowly when a
force of 700 N (400 N for motorcycles and mopeds) is applied to it for 1 min.
7.6 For vehicles using a compressed air braking servo, when the air pressure reaches 600 kPa under no
braking and the air compressor stops for 3 min, the air pressure’s decrease should not be more than 10kPa.
Push the braking pedal in fully when the air pressure reaches 600kPa, observe the air pressure for 3 min after it
stabilises, the pressure decrease should not be more than 20 kPa for motor vehicles and 30 kPa for motor
vehicle combinations, articulated passenger cars, articulated trolley buses and transportation tractor
combinations.
7.7 For vehicles using a compressed air braking servo, after 4 min (6 min for motor vehicle combinations
and 8 mm for articulated passenger cars and articulated trolley buses) when the engine is running at 75% of its
rated speed, the air pressure gauge indicated pressure should reach the vehicle starting pressure from 0 (using
400 kPa for vehicles without a starting pressure).
7.8 The compressed air braking system should have a pressure limit device to make sure the air pressure in
the air tank will not exceed the allowed maximum pressure.
13
GB 7258—200×
7.9 The driving brake system of any motor vehicle (excluding three-wheel vehicles) should use double loop
or multi loop systems. When some of the pipes are not working, the remaining pipes can still achieve more
than 30% of the specified efficiency.
7.10 During driving no automatic braking should occur. When the trailer (excluding trailers with loading
masses below 3000kg and towed by wheeled tractors) is disconnected from the towing vehicle accidentally, the
trailer should be able to brake automatically and the towing vehicle’s brake will still be available.
7.11 Air Tank
7.11.1 Compressed Air and Vacuum Protection
Any Vehicle with an air tank or vacuum canister should use a one-way valve or other protection device,
so that if the connection between the tank (or canister) and the compressed air source fails or leaks, the
compressed air (or vacuum) will not lose effectiveness completely.
7.11.2 The capacity of the air tank should guarantee that under the maximum pressure adjusted by the
adjustment valve and without further charge, the pressure will not be lower than the start pressure (using 400
kPa for vehicles without a starting pressure) after fully pushing the braking pedal 5 times.
7.11.3 The air tank should have a dirt release valve.
7.12 Brake Warning System
7.12.1 For vehicles using hydraulic braking, the fluid reservoir top-up should be easy to access. The
structural design should enable the fluid level to be checked without opening the container. If this is not the
case, there should be a low fluid level warning device.
7.12.2 For vehicles using hydraulic braking (excluding three-wheel vehicles and single cylinder diesel low
speed goods vehicles), when any hydraulic transmission part fails, there should be a red warning signal to
inform the driver and the signal should not be later than brake activation. The signal should remain on as long
as the failure still exists while the ignition switch is at the ON (running) position. The warning signal should be
eye catching even in daylight, the driver should be able to check the warning lights easily from his seat and
failure of this device should not make the braking system fail completely.
7.12.3 For vehicles using compressed air braking, when the control system’s air pressure is lower than the
start pressure (using 400 kPa for vehicles without a starting pressure), the warning device should give an easy
to hear or easy to see continuous signal to the driver.
7.12.4 For vehicles with an antilock braking unit, when the antilock braking unit fails, the warning device
should give an easy to hear or easy to see continuous signal to the driver.
7.13 Road Braking Performance Check
The test for motor vehicle’s driving brake and emergency brake performance should be carried out on a
flat, solid, clean, dry concrete or tarmac road with the adherence coefficient less than 0.7. The engine should
be disconnected during the test.
7.13.1 Driving Brake Performance Test
Using Braking Distance to Check Braking Performance
The motor vehicle’s braking distance and braking stability should conform to Table 3 at the specified
initial speed. If there is any doubt on the braking distance result without load, a full load braking distance test
can be carried out using Table 3.
The braking distance refers to the vehicle’s travelling distance from the foot touching the brake pedal (or
the hand touching the brake handle) to execute the emergency braking at the specified initial speed until the
vehicle has stopped.
The braking stability requires that during braking any part of the vehicle (excluding non vehicle width
parts) is not allowed to exceed the edge of the test route by a specified width.

（specification appendix）
Speedometer Indicating Error Test Method
A1 The speedometer indicating an error test should be carried out on a roller type speedometer tester. A road
speedometer indicating error test can be carried out for vehicles (such as four wheel drive vehicles, vehicles
with anti drive skidding mechanism etc), which cannot be tested on a roller speedometer tester.
A2 The test to establish whether the vehicle is up to standard is as follows: the wheels of the vehicle must be
rotating, the speedometer indicates a speed V1 reaching 40 km/h, if the speed indicated by the tester V2 is
between 32.8 km/h ~ 40 km/h, then the vehicle being tested is up to standard.
When the speed indicated by the tester V2 reaches 40 km/h, if the vehicle’s speedometer indicated speed V1 is
between 40 km/h ~ 48 km/h, the vehicle under test is up to standard.
Appendix B
（specification appendix）
Side Slip Value Testing Method for the Turning Wheel
B1 The side slip of the turning wheel should be carried out on a side slip tester.
B2 Set the vehicle directly facing the side slip tester with the steering wheel in the middle position;
B3 Drive the vehicle along the indicated line on the slip plate with a stable constant speed of 3 km/h～ 5
km/h without turning the steering wheel;
B4 Measure the side slip value when the vehicle is passing the test plate.
Appendix C
（specification appendix）
Braking Performance Test Method
C1 Braking Test on Road
C1.1 The braking performance test on road should be carried out on a flat (slope less than 1 %), dry and
clean solid road (with the adherence coefficient between the tyre and road less than 0.7).
C1.2 Draw the side lines of the test passage on the road with the width specified in Table 3. Drive the vehicle
along the middle line of the road. When the speed reaches the specified initial speed, change the gear to the
neutral (set the transmission to D for auto transmission vehicles). When the vehicle is sliding the initial speed,
carry out an emergency stop to bring the vehicle to a halt.
C1.3 When checking the vehicle’s braking performance by braking distance, use the speedometer, the fifth
wheel tester or other instruments to measure the braking distance. With the exception of vehicles with
pneumatic braking system, the force on the braking pedal (hand operating force) should be measured at the
same time.
30
GB 7258—200×
C1.4 When using Mean Fully Developed Deceleration (MFDD) to check the braking performance, use
instruments to measure MFDD and the braking coordinating time. With the exception of vehicles with
pneumatic braking system the force on the braking pedal (hand operating force) should be measured at the
same time.
C2
Braking Performance Test by Tester
C2.1 The roller surface of the tester should be dry and without any loose materials and smears. The
adherence coefficient on the roller surface should not be less than 0.75.
To obtain enough adherence force during the braking test, adding additional mass or the force equivalent
to the additional mass on the vehicle (the additional mass or force is excluded in the axle load) is permitted.
Measures to prevent the vehicle from moving (such as triangle stops or fixing wires) can be taken during
the test. When the above actions are taken and there are still wheel locking and slipping on the roller or the
whole vehicle is moving backwards with rollers, the braking force is not up to standard and it needs to be
tested by other methods specified in this standard.
C2.2 Using Platform Braking Tester
The platform surface of the tester should be dry and without any loose materials and smears. The
adherence coefficient on the platform surface should not be less than 0.75.
Drive the vehicle directly on to the platform braking tester at a speed of 5 km/h ~ 10 km/h (or the testing
speed recommended by the manufacturer), place the gear in neutral (set the transmission to D for auto
transmission vehicles), carry out an emergency stop to halt the vehicle and measure the values required in 7.14.
C3 Selection of Test Method
When considering using the roller braking tester or platform braking tester to check the vehicle’s braking
performance during the technical safety test, the platform braking tester is more suitable for passenger cars
with front axle driving.
A road braking test should be used for vehicles unsuitable for braking testers or there is doubt on the
result from braking testers.
For goods vehicles and trailers with full load/empty load ratio exceeding 2.0, it is better to have the
braking test with additional load (or full load), the additional load should be calculated in the axle load and the
gross mass of the vehicle in this situation. For vehicles under full loading, the entire braking force percentage
of the vehicles should be tested as full load test; if the load is not full, the entire braking force percentage of the
vehicle should be tested as a weighted value of the full axle load and the empty load.
