Trailers are divided into two types: full trailers and semi-trailers. A full trailer bears its total weight entirely by itself, while a semi-trailer shares part of its total weight with the towing vehicle. The differences between full trailers and semi-trailers are as follows: 1. The connection method with the towing vehicle differs. A full trailer connects its front end to the rear of the towing vehicle, which only provides pulling force without bearing weight. A semi-trailer rests the front half of its body on the fifth wheel coupling of the towing vehicle, with the rear axle of the towing vehicle bearing part of the trailer's weight. 2. Full trailers can increase cargo capacity, reduce fuel consumption, and thereby lower transportation costs. Semi-trailers must not exceed 17 meters in length, except for car carrier semi-trailers.

Is There a Fine for Not Wearing Seat Belts in the Back Seat of a Car?

Whether there is a fine for not wearing seat belts in the back seat varies by city. Taking Shenzhen as an example, passengers in the back seat not wearing seat belts will be fined. Since July 4, 2016, Shenzhen traffic police have strictly enforced penalties for passengers not wearing seat belts, and the driver will also be penalized if back-seat passengers are not buckled up. Relevant information about car seat belts is as follows: 1. Introduction: Car seat belts are safety devices designed to restrain occupants during a collision and prevent secondary collisions with the steering wheel, dashboard, etc., or to avoid injuries from being thrown out of the vehicle. 2. Working Principle: The retractor contains a ratchet mechanism. Normally, occupants can pull the webbing freely and at a constant speed, but when the webbing stops being pulled out continuously or the vehicle encounters an emergency, the ratchet mechanism locks automatically, preventing further extension of the webbing.

Why does parallel parking result in crossing the line?

Parallel parking results in crossing the line because the opportunity to turn the steering wheel to the left after the car body forms a 45° angle with the sideline is not well grasped, and the steering wheel is turned too late. When entering the parallel parking test area, it is necessary to find the right parking position and maintain a distance of about 30cm between the right side of the car body and the sideline. A distance that is too large or too small will lead to crossing the line. Without poles as reference objects, it is necessary to learn to use the rearview mirror to identify the marking lines. Here are some practice tips: 1. When the left front corner of the garage disappears in the right rearview mirror, turn the steering wheel to the right to the limit and continue reversing while watching the left rearview mirror. 2. When the bottom line of the garage is completely visible, straighten the steering wheel, continue reversing the car, and keep watching the left rearview mirror.
