What are the precautions for wedding cars on highways?

Precautions for wedding cars on highways include vehicle type and lighting requirements. Vehicle type requirements for wedding cars on highways: Wedding cars must comply with the regulations in the "Highway Traffic Management Regulations" to be allowed on highways. Wedding cars are generally small vehicles with 7 seats or fewer, such as small cars or minivans, which are permitted on highways. Lighting requirements for wedding cars: Wedding cars are not allowed to use hazard lights to maintain formation on highways. Generally, hazard lights are not permitted on highways unless in special emergency situations. Hazard lights are intended for emergency use only. Typically, they can be used in situations such as sudden vehicle malfunctions while driving, extreme weather conditions, or vehicles engaged in rescue operations or transporting critically ill patients.

Why Does the Steering Wheel Make Noise When Turning?

Steering wheel noise during turning is related to bearings, the engine, and interfering components. Bearing factors: As the core component bearing the vehicle's weight and providing rotational capability to the tires, bearings may become damaged under daily stress, affecting driving performance. Engine factors: Technical conditions of certain engine mechanisms may have changed due to excessive part wear, improper assembly or adjustment; or reduced lubrication between components leading to dry friction sounds. Interfering component factors: Interference with adjacent components causing plastic deformation, or insufficient grease between friction surfaces in the steering system resulting in dry or semi-dry friction that produces abnormal noises. Solutions: Noise during initial turning is likely caused by failed shock absorber pressure bearings - replacement is needed. This issue also relates to routine maintenance. Regular inspections for part wear should be conducted, with lubrication added to bearing components to reduce friction.

Which has priority, left lane change or right lane change?

At intersections, left turns have the right of way. Below is relevant information about intersections: 1. Introduction to intersections: An intersection refers to a level crossing where two or more roads meet on the same plane. On December 1, 2017, the "Specification for English Translation in Public Service Areas" was officially implemented, stipulating that the standard English term for an intersection is Crossroads or Intersection. 2. Roads: Here, roads refer to all roads as defined in the supplementary provisions of the "Road Traffic Safety Law," including urban roads, alleys, lanes, and highways. However, the intersection of alleys or lanes with sidewalks on both sides of urban streets is not considered an intersection; the level crossing of highways with rural paths not classified as highways is also not considered an intersection; nor are level crossings of railways and roads considered regulated intersections here. For motor vehicle passage at railway crossings, the "Road Traffic Safety Law" and the "Implementation Regulations of the Road Traffic Safety Law" have specific provisions.

Why Can't You Drive When the Transmission Warning Light Is On?

You should not continue driving when the transmission warning light is on. Reasons: Do not blindly continue driving to prevent severe damage to the transmission. If the transmission warning light is on but the engine speed and vehicle speed are normal, you may continue driving. However, if any driving issues arise, visit a 4S shop as soon as possible to check for faults and avoid potential hazards. Function of the Transmission: The transmission changes the gear ratio, expands the range of torque and speed variation of the driving wheels, and allows the vehicle to reverse while maintaining the engine's rotation direction. It enables engine startup and gear shifting. The transmission consists of a gear transmission mechanism and a control mechanism. Precautions: If the electronic components of the automatic transmission (sensors, solenoid valves, or the control module) experience intermittent or persistent failures, the engine warning light may illuminate. In such cases, remain vigilant and promptly check for any faults.

17-inch Wheels: 215 or 225?

If the original vehicle has 195/65/R15 tires, switching to 225/45/R17 is the most suitable option as there will be no change in diameter and circumference, ensuring no deviation in the speedometer and odometer. Using 215 tires may result in a slight deviation, but the impact is minimal. Below is the relevant information: 1. Wheel Hub: The wheel hub is the rotating part of the wheel steel connected through pillars inside the tire, which is the metal component mounted on the axle that supports the tire. It is also known as the wheel rim, steel rim, or tire ring. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Size: The wheel hub size refers to the diameter of the wheel hub, with 15 and 16 inches indicating the size (diameter) of the wheel hub. Generally, in passenger cars, larger wheel hub sizes with higher tire aspect ratios can create a visually appealing tension effect and improve the stability of vehicle handling. However, this comes with the additional issue of increased fuel consumption.

Should the foot always stay on the accelerator in a manual transmission car?

In a manual transmission car, the foot does not need to stay on the accelerator all the time. When braking is needed, the foot should be placed on the brake pedal. Pre-departure check: Before setting off each day, conduct a comprehensive vehicle inspection, including checking for oil or water leaks, measuring tire pressure to ensure it is appropriate, inspecting the engine oil condition to verify its color is normal and the oil level is correct. Safe driving: Use seat belts correctly. In the event of a severe collision, seat belts provide protection no less effective than airbags. Avoid fatigued driving and take breaks every 2 hours. Traffic rule compliance: Especially on highways, do not exceed speed limits. Speeding may not only result in traffic police penalties but, more importantly, is unsafe.
