Honking at Traffic Lights is Prohibited, What to Do if You Honk?

Honking at traffic lights is prohibited and may result in a fine. Motor vehicle drivers who honk in no-honking zones or during prohibited times are committing a traffic violation and should be penalized according to the law. Relevant information about traffic lights is as follows: 1. Introduction: Traffic lights are signals that direct traffic flow, typically consisting of red, green, and yellow lights. A red light means stop, a green light means go, and a yellow light serves as a warning. 2. Control Methods: The most basic control method is timed control at a single intersection. Line control and area control can also use timed control methods, known as static line control systems and static area control systems.

What Does the Yellow Exclamation Mark Mean in a Toyota Vehicle?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, or lighting system fault. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission issue or that the transmission fluid level is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line with an exclamation mark below a parenthesis represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. Additionally, a red exclamation mark inside a circle with parentheses indicates a braking system warning, typically due to braking system failure or low brake fluid level. Immediate inspection of the braking system is necessary to avoid accidents.

Where to Replace a Dead Car Key Battery?

You can replace a dead car key battery at a 4S dealership. Below are detailed specifications of car key battery models: 1. CR2016 battery: This is highly common in car key remotes. With a voltage of 3V, most car key batteries operate on 9V power, requiring replacement of all three batteries each time. Models like Honda, Toyota, Volkswagen, Mazda, etc., use this type. The CR2016 measures 20mm in diameter and 1.6mm in thickness. 2. CR2025 battery: Far less common than CR2016. It's thicker than the 2016 but offers higher energy storage. The CR2025 measures 20mm in diameter and 2.5mm in thickness, mostly found in audio system remotes. 3. CR2032 battery: Also with a 3V voltage, its capacity reaches about 200mAh, making it twice as thick as the CR2016.

What to Do When Traffic Lights and Road Signs Are Inconsistent?

Observing traffic signals should follow this priority order: traffic police > traffic lights > overhead signs > road markings. Below are detailed explanations: 1. Traffic lights: If there's a conflict between traffic lights and a traffic officer's gestures, always follow the officer's instructions. 2. Inconsistency: Driving based solely on noticing overhead signs before seeing road markings will definitely result in penalties. 3. Conflicting traffic signals: When there's a discrepancy between an officer's gestures and traffic lights, the officer's directions take precedence.

What Causes the Air Volume of Car Air Conditioning to Fluctuate?

Car air conditioning air volume fluctuations are caused by the cooling fan constantly starting and stopping. Here are the relevant explanations: 1. Electromagnetic switch: An electromagnetic switch is at work, causing the air conditioning compressor to operate after being energized. The adsorption force generated during this process creates certain noises and slight vibrations. 2. Compressor: The car air conditioning compressor is different from household air conditioning compressors. Household compressors operate directly when powered, while car compressors are driven by a belt after being energized and adsorbed. Therefore, when the cooling switch is turned on, electromagnetic adsorption consumes electrical energy, and the belt-driven pump head (car air conditioning compressor) also consumes engine power.

How many points are deducted for stopping at a red light but reversing?

If only the front wheels cross the stop line after the red light, while the rear wheels do not, and then the car reverses back behind the stop line, this triggers the electronic eye to take a photo once when crossing and again when reversing. Although this does not count as running a red light, it is still a traffic violation. If the reversal is illegal, a warning or fine may be imposed. Below is the working principle of red light cameras: 1. Pressure sensing by induction lines: Electronic eyes use induction lines to sense the pressure from vehicles on the road. The signal is collected by sensors and sent to the central processor, where it is temporarily stored in a register (this data is valid within one red light cycle). 2. Pulse signals: Within the same time interval (red light cycle), if two pulse signals are generated simultaneously, it is considered 'valid.' That is, if the front wheels cross the line during a red light while the rear wheels do not, only one pulse is generated. Without two consecutive pulses, no photo is taken.
