Are Tourist Vehicles Considered Commercial Vehicles?

Tourist vehicles refer to tour buses operated by transportation companies, which can be chartered and are classified as commercial vehicles owned by private entities. Introduction to Tourist Coaches: A tourist coach (touring coach) is a type of bus specifically designed and equipped for tourism purposes. The layout of these vehicles ensures passenger comfort and does not accommodate standing passengers. Simply put, it is a small passenger vehicle with no more than 17 seats. In China, due to their shape, they are commonly referred to as "bread vans." Tourist coaches are highly maneuverable and offer superior ride comfort. Common Issues with Tourist Coaches: For example, consider an 8-meter rear-engine coach equipped with a domestically produced four-cylinder turbocharged, electronically cooled diesel engine. Most domestically produced coaches exceeding this length typically use six-cylinder engines. While similar issues may arise, the lifespan of certain components and the timing and symptoms of faults can differ.

Why does the handbrake light stay on after releasing it?

The reasons why the handbrake light stays on after releasing it are as follows: Brake system malfunction: If the dashboard light remains on after releasing the handbrake, it indicates a fault in the brake system. If the light stays on continuously, it is usually caused by insufficient brake fluid or excessive wear of the brake pads. It is recommended to first check whether the brake fluid is sufficient. If the brake fluid is low, simply top it up. Excessive brake pad wear: Excessive wear of the brake pads can also cause this issue. You can go to a professional repair shop to replace the brake pads. If there is no fault in the brake system, the problem may lie with the handbrake switch. It is advisable to visit a professional 4S shop for repairs, as the car's braking system is not a trivial matter.

What Causes Body Vibration When a New Car is in P Gear?

The reasons for body vibration when a new car is in P gear are as follows: Increased Engine Load and Reduced Power: For automatic transmission models, slight vibration when shifting gears is a normal phenomenon, which is caused by increased engine load and reduced power. Abnormal Engine Idle Operation: If the vibration is more noticeable, it indicates abnormal engine idle operation. It is necessary to inspect the aspects that may cause abnormal engine idling. If the fault light is on, locate the faulty part according to the fault code. If the fault light is normal, check whether the air filter is excessively clogged with dust, then check for any cylinder misfires, and further inspect whether the high-voltage ignition system and fuel injection system of the misfiring cylinder are functioning abnormally.

Are the batteries of new energy vehicles replaced for free?

New energy vehicle batteries can indeed be replaced for free within the warranty period, but there are some restrictions. Some manufacturers also have special warranty regulations. Introduction to New Energy Vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. Classification of New Energy Vehicles: New energy vehicles include hybrid electric vehicles (HEV), battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), hydrogen engine vehicles, as well as gas vehicles, alcohol ether vehicles, etc.

Where is the choke open position on Honda 125?

On the Honda 125, moving the choke lever upwards opens it, while moving it downwards closes it. Choke construction: There are two types of choke construction. One is an automatic electric choke, and the other is a manual choke. The manual choke is more intuitive, offers stable control, and requires no adjustments. The driver simply feels the length of the cable pulled out to adjust the mixture concentration. Function of the choke: During cold engine starts, the choke partially closes the air intake to increase the fuel concentration in the air-fuel mixture entering the cylinder, improving engine starting performance. Once the engine is running normally, the choke should be fully opened. Otherwise, an overly rich mixture can cause the engine to malfunction and increase fuel consumption. In fuel-injected engines, this process is automatically controlled and requires no manual operation.

Is it allowed to make a U-turn at an intersection without traffic lights?

It is allowed to make a U-turn at an intersection without traffic lights. Permissible U-turn scenarios are as follows: Presence of U-turn signal lights or signs: When there is a U-turn signal light at the intersection, a U-turn can be made when the U-turn indicator is green. If there is a U-turn sign or a lane marking indicating U-turn permission, a U-turn can be made while ensuring the safety of oneself and others. No U-turn sign but left turns are allowed (no prohibition signs): Vehicles can make a U-turn at intersections where left turns are permitted and no U-turn prohibition signs or markings are present. Note that vehicles must proceed according to the left-turn signal light without disrupting the normal flow of other vehicles. If making a U-turn at an intersection with a left-turn waiting zone, you may enter the waiting zone when the straight signal is green and wait until the left-turn signal turns green before making the U-turn. U-turns are allowed at dashed lines: Both white and yellow dashed lines permit U-turns. For double yellow lines (one solid, one dashed), check whether your side is dashed. If it is, a U-turn is allowed safely; if solid, U-turns are prohibited. At intersections with double yellow lines, U-turns can be made on the dashed side but must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Yellow grid areas prohibit parking, but as long as there is no central barrier, a U-turn can be made after yielding to normally moving vehicles. U-turns are allowed on the dashed side of a green belt: When the green belt has dashed lines ahead, vehicles on that side can make a U-turn there. If the green belt has solid lines ahead, vehicles must obey the traffic signal, cross the pedestrian crossing before making a U-turn, and must not cross solid lines or the pedestrian crossing.
