Overloaded vehicles and insurance

Generally, the maximum capacity of minivans is around 2.8 tonnes. As for other forms of commercial vehicles such as trucks, the loading capacities vary, and can be found in the vehicle registration documents.

As for non-commercial vehicles, it depends on the car specs. While there is normally no specification on the maximum weight (since these cars are not designed to carry goods in the first place), there is a maximum number of passengers.

According to section 37(5) of the Road Traffic Ordinance (Cap.374 of the Laws of Hong Kong), a person “is also to be regarded as driving dangerously…if it would be obvious to a competent and careful driver that driving the motor vehicle concerned in its current state would be dangerous”. Therefore, driving an overloaded commercial vehicle such as a minibus could amount to dangerous driving.

Offenders are liable on first conviction to a penalty of $5,000 and imprisonment for 3 months and on second or subsequent conviction to a fine of $10,000 and imprisonment for 6 months. The owner of the overloaded vehicle may also commit an offense and is liable on first conviction to a penalty of $5,000 and on second or subsequent conviction to a fine of $10,000.

Other than the aforementioned legal consequences, overloading your car will also harm the safety of your own and other road users. After all, a vehicle with loads heavier than its designed specifications will not perform as it is intended to and may result in the following malfunctions:

• The excess weight may cause your wheels to bulge out and heat up, thereby increasing the risk of a blowout.

• Your suspension/traction control will not be able to handle highway speeds appropriately. The suspension system comes under stress, and, with wear and tear over time, the weakest point can give way.

• Your breaks will become less effective so that you will need longer stopping distances, especially during rainy weather.

• It will be harder to steer the car in a straight line and round bends safely, or steering may become unresponsive and unpredictable altogether. It will increase the likelihood of overturning.

• Sudden steering/maneuvering is almost certain to end in a spinout. Also, if you travel at a high speed and stop abruptly, any unfastened item may come loose and fly out of the car.

• If you pack your back seat with bulky items such as mattresses, it may block mirrors and windows and impair your rear vision.

• Not only will it cause significantly increased wear and tear in brakes, tires, and suspension control, but it will also wear out the road infrastructure.

• Gas costs will rise significantly due to excess weight.

To check how much weight each tire can carry, you can refer to your tire code, which is an ISO metric used by almost every tire manufacturers around the world. It will likely look something like P205/60R15 70H. In this example, you can refer to the fourth number (70) and third letter (H), namely the load index and speed symbol. 70 means 335 kg per tire. You can check out our previous article for more information about tires. Wikipedia also features an overview of what different numbers and symbols mean in the tire code.

Contrary to popular beliefs that overloading will not be covered, the fact is that insurers typically may still compensate you for any damages, liabilities, and injury in an accident caused by an overloaded car. However, the reimbursement may not be 100% since overloading is still an intentional, unlawful behavior.

You should also note that some insurers may specifically list overloading as an exclusion in the insurance policy, in which case the policyholder will not get any compensation if he or she overloads the car.
