Are there any safety standards for gasoline tricycles?

Yes,gasoline tricycles(classified as three-wheeled motor vehicles/three-wheeled automobiles in China)are governed by strict national safety standards to ensure structural integrity,braking performance,stability,and operational safety.Below are the core mandatory and recommended standards:

Main Chinese National Safety Standards

GB 18320-2025(Mandatory)—Safety Technical Specifications for Three-Wheeled Automobiles

The core safety standard(replaces older GB 18320-2001).

Covers:braking systems,stability(rollover angle),frame strength,steering,lighting,mirrors,seatbelts,fuel tank safety,and emissions.

Requires:dual rear brakes,parking brake holding on 20%slopes,no self-application of brakes,wear compensation,and operable controls from the seat.

GB/T 24945-2021—General Specifications for Three-Wheeled Automobiles

Defines dimensions,load capacity,engine performance,and basic safety matching GB 18320.

GB/T 21423-2025—Safety Requirements&Test Methods for Fuel Tanks

Specifies leak resistance,crash performance,and fire safety for gasoline tanks.

GB 1589—Limits of Dimensions,Axle Load,and Mass

Governs maximum size and legal load limits.

Key Safety Requirements Covered

Braking:Dual-circuit or dual rear brakes;strong,stable,no pulling;effective when hot.

Stability:Minimum side-tilt stability angle to prevent rollovers.

Frame&Body:Reinforced steel,quality welds,no sharp edges;cargo bed cannot have factory structures for illegal modification.

Fuel System:Leak-proof tank,secure mounting,fire-resistant materials.

Lighting&Signals:Headlamps,turn signals,brake lights,horn,mirrors(per GB 19134).

Controls:Throttle,clutch,gearshift must be safe and not jam;reverse interlock.

Emissions:Engine must meet national motorcycle/three-wheeler emission limits(e.g.,China IV/V).

International&Regional References

US/ANSI:Z315.1(consumer tricycles)and ASTM WK72208(juvenile products)—not directly for heavy cargo gasoline tricycles.

EU:ECE R11(brakes),R75(motorcycles/tricycles),and emission rules apply to exported models.

Compliance Check When Buying

Vehicle must be in the MIIT(Ministry of Industry and Information Technology)catalog.

Must have a VIN code,certification mark,and comply with GB 18320.

Avoid unbranded/non-compliant units that lack safety features and cannot be licensed or insured.
