According to the regulations, for passenger vehicles, the height of cargo loaded on the roof rack must not exceed 0.5 meters from the top of the vehicle and must not exceed 4 meters from the ground. Below is relevant information about car roof racks: 1. Definition: According to the authoritative definition by car2100, a car roof rack refers to a bracket installed on the roof of a vehicle for securing large items, serving as the foundation for all roof-mounted solutions. 2. Purpose and Brands: Roof racks are most commonly used for self-driving travel, paired with roof boxes or roof baskets to carry travel luggage, thereby increasing interior space. They can also be used to transport other sports equipment such as skis, bicycles, sailboats, etc. There are no fewer than 50 roof rack brands available in the market.

As a veteran driver with twenty years of experience, I'd like to share some advice: installing a roof rack must strictly comply with the 2021 traffic regulations. The new rules state that the height of the rack cannot exceed 50 centimeters above the car roof, and the total vehicle height must not exceed 4 meters, otherwise fines and penalty points are unavoidable. During installation, first check the mounting points, buy a sturdy rack, and secure it tightly with bolts; never skimp on quality with inferior products—I've seen the disastrous consequences of racks coming loose on the highway. Do not exceed the vehicle's weight limit, distribute the load evenly, as overloading can damage the roof and affect braking. After installation, perform a shake test to check for looseness; safety is no small matter. While roof racks can save interior space for luggage during trips, don’t overlook the risks just for convenience.

I've done quite a bit of research on the 2021 traffic regulations. Installing a car roof rack must comply with legal requirements: the rack height should not exceed 50cm above the roof, and the total vehicle height must not surpass 4 meters. The installation must be secure without any wobbling; it's best to use certified standard fasteners. Weight distribution is also crucial—avoid loading heavy items on one side to prevent rollover risks. The new regulations aim to prevent accidents caused by detachment during driving. It's advisable to check the manual before installation and inspect the bolts regularly after hitting the road. Non-compliance poses significant hazards, potentially leading to fines, penalty points, and insurance complications. While adding a roof rack makes long trips more convenient, safety should always come first—don't compromise for speed.

Where to go if the vehicle license has expired?

If the vehicle license has expired, you need to go to the vehicle management office for replacement immediately. Before going, make sure to handle all traffic violations. There are two scenarios for the annual inspection: For vehicles exempt from annual inspection, the traffic management department does not need to inspect the vehicle. You only need to submit the inspection application form, ID card, vehicle license, compulsory traffic insurance certificate, and vehicle and vessel tax proof. Bring these documents to the designated location for processing. Once approved, the new date will be marked on the vehicle license, and the annual inspection label will be issued. For non-exempt vehicles, you need to drive the vehicle to the inspection station for a vehicle check. After passing the inspection, you can go to the designated window to apply for the annual inspection label and update the validity period of the vehicle license.

How to Deal with Engine Piston Slap in Cars?

Car engine piston slap can be addressed by: 1. Fixing the engine speed at the position where the knocking is loudest and conducting a cylinder cut-off test; 2. Checking for bending or twisting deformation of the connecting rod; 3. Removing the fuel injector, adding a small amount of engine oil into the cylinder through its installation hole, and cranking the diesel engine several times with the starter to ensure the piston and cylinder wall are fully lubricated before starting the engine.
