Generally, changing lanes is not allowed on double yellow dashed lines. Here are the detailed explanations: 1. Regulations: Double yellow dashed lines serve as road dividers, and changing lanes is prohibited. Crossing these lines is considered driving against traffic and will be penalized as such, with full responsibility in case of an accident. However, if the double yellow dashed lines are used as tidal flow lanes, changing lanes is permitted under the condition of ensuring safety and not affecting other vehicles. Therefore, the specific function of double yellow dashed lines varies, leading to different handling methods. Considering that tidal flow lanes are relatively new markings, it is understandable that many people believe changing lanes on double yellow dashed lines is not allowed, and not changing lanes in tidal flow lanes is also acceptable. 2. The purpose of double yellow dashed lines: Crossing double yellow lines is not allowed. Depending on the road conditions, drivers may have different choices. For instance, some roads are marked with double solid yellow lines, indicating that crossing these lines or making U-turns is prohibited, and both actions are considered traffic violations. On the other hand, double yellow dashed lines allow for U-turns or left turns to the right side of the opposite lane, provided safety is ensured. Thus, they function as an exit but not as an option for driving against traffic.

What is Fully Synthetic Oil and Semi-Synthetic Oil?

Fully synthetic oil is blended using Group III, IV, and V base oils, while semi-synthetic oil uses Group III base oil. The functions of engine oil are: 1. As a lubricant, it reduces friction and wear between moving parts; 2. As a coolant, it absorbs heat generated in the engine combustion chamber and piston crown, cooling the engine and preventing overheating. The differences between fully synthetic and semi-synthetic oils are: 1. Different base oils: Fully synthetic oil is blended from Group III, IV, and V base oils; semi-synthetic oil uses Group III base oil. 2. Different replacement intervals: Fully synthetic oil should be replaced annually or every 10,000 kilometers; semi-synthetic oil should be replaced every six months or 7,500 kilometers.

How much earth can a front-four-rear-eight dump truck carry?

Front-four-rear-eight dump trucks typically carry around 30 cubic meters of earth. More information about front-four-rear-eight dump trucks is as follows: Definition: Front-four-rear-eight is a category of commercial vehicles, meaning the front steering wheels consist of two axles with four wheels, and the rear drive wheels consist of two axles (bridges) with dual wheels each, totaling eight wheels. Common "front-four-rear-eight" vehicles include various dump trucks, heavy-duty trucks, and trailer trucks. Load capacity: Primarily determined by the vehicle's horsepower and the specifications of the cargo box. To carry more cargo, a semi-trailer can be added. Overloading can easily lead to tire blowouts, rollovers, and other accidents. Additionally, if caught by traffic police, fines and demerit points will be imposed.

Why does the engine oil light flash while driving?

During driving, the engine oil light flashes due to insufficient oil level or a clogged oil filter. Below is more relevant information: 1. Detailed causes: (1) Insufficient oil level reduces the oil pump's output or prevents oil from being pumped due to air intake, leading to a drop in oil pressure. (2) Engine overheating accelerates oil aging, deterioration, and thinning, potentially causing leakage through gaps and resulting in pressure loss. (3) A clogged oil filter can cause the oil pump's pressure to rise or fall. 2. Normal oil light behavior: The oil light turning on and off intermittently occurs when the vehicle performs a self-check after power-on. The oil light will illuminate during this time. Once the vehicle runs for a while and the self-check system confirms normal oil pressure, the light will automatically turn off, which is a normal phenomenon.

Which distance is not included in the stopping sight distance?

Stopping distance does not include the starting distance. The following is an extended introduction: 1. Introduction to stopping sight distance: Stopping sight distance refers to the shortest driving distance required for a vehicle to stop when encountering an obstacle ahead while driving on the same lane. Stopping sight distance can be broken down into three parts for study: reaction distance, braking distance, and safety distance. Simply put, stopping sight distance is the shortest distance required for the driver to stop before discovering an obstacle. 2. Composition of stopping sight distance: Stopping sight distance consists of three parts: the distance S₁ traveled during the driver's reaction time, the distance S₂ traveled from the start of braking to the complete stop of the vehicle (braking distance), plus a safety distance S₀ (5~10m).
