Black 40 with three slashes means lifting the 40 km/h speed limit. It belongs to the prohibition signs in traffic signs. These are signs that can impose prohibitions or restrictions on vehicles, such as no entry, no parking, no left turn, no honking, speed limits, weight limits, etc. Prohibition signs are usually circular in shape, with some being octagonal or equilateral triangles with the vertex pointing downward. Their colors are typically white background, red circle, red slash, and black pattern. The no parking sign features a blue background, red circle, and red slash. Legal basis: Article 38 of the 'Road Traffic Safety Law of the People's Republic of China' states that vehicles and pedestrians shall follow traffic signals; when traffic police are directing on site, they shall follow the directions of the traffic police; on roads without traffic signals, they shall proceed under the principle of ensuring safety and smooth traffic. Article 44 states that motor vehicles passing through intersections shall follow traffic lights, traffic signs, traffic markings, or the directions of traffic police; when passing through intersections without traffic lights, traffic signs, traffic markings, or traffic police directions, they shall slow down and yield to pedestrians and vehicles with the right of way.

Does the Elantra make a plastic friction noise when turning the steering wheel?

The Elantra may produce a plastic friction noise when turning the steering wheel. Here are the possible reasons for the steering noise in the Elantra: 1. Friction between plastic components: The steering wheel is composed of various plastic parts, and if the gaps between them are too small, friction can occur when the steering wheel is turned. 2. Friction between the steering column and the floor mat: If the aftermarket floor mat is too large and comes into direct contact with the steering column, friction will occur as the steering column rotates. 3. Faulty clock spring in the steering wheel: If the clock spring is broken or its connector is not properly plugged in, it should be replaced or secured.

Why does the car still pull to one side when the four-wheel alignment data is correct?

The four-wheel alignment data is correct but the car still pulls to one side because the tire tread patterns on both sides are different or the tread depth is uneven. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are rubber products and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low. Tires can also age if left unused for long periods, so it's important to check the production date when purchasing new tires.
