How wide is approximately 30cm in the rearview mirror?

What is the safe following distance at 100 km/h on the highway?

On the highway, the safe following distance at 100 km/h should be over 100 meters. Below are specific guidelines for high-speed driving: 1. Pre-drive vehicle inspection: Before entering the highway, check the braking system and tire pressure/wear condition. This prevents insufficient emergency braking and ensures optimal tire pressure (both underinflation and overinflation are hazardous for high-speed driving and may cause blowouts). 2. Seatbelt usage: All occupants, including rear-seat passengers, must wear seatbelts during high-speed driving, regardless of road type. 3. Lane discipline: Highway lanes are clearly marked for specific vehicle types (e.g., large vehicles, passenger cars). When overtaking, return to your designated lane promptly after completing the maneuver—avoid prolonged occupation of other lanes.

What is the speed limit on highway auxiliary roads?

Highway auxiliary roads have a speed limit of 40 km/h. Below are specific details about highway speed limits: 1. Regulations: According to the Road Traffic Safety Law, the maximum speed for passenger cars on highways must not exceed 120 km/h, while other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h. 2. How long does it take to detect speeding: Speeding violations on highways are typically recorded and can be checked online within 3 to 7 days, with the latest not exceeding 13 working days. However, if the speeding violation occurs outside of highways (e.g., in another region), it may take about 2 to 3 weeks to be recorded and checked.

Should You Call the Police If Your Car Breaks Down on the Highway?

If your car breaks down on the highway, you can call the police or dial 122 for road rescue. Here are some precautions to take when your vehicle breaks down on the highway: 1. Turn on the hazard lights: If your vehicle is unable to move due to a malfunction or accident and cannot leave the driving lane, immediately turn on the hazard warning lights and set up a warning sign 150 meters behind the vehicle. At night, also turn on the width marker lights and taillights. 2. Emergency avoidance: If your car breaks down on the highway and requires repairs, even if you are repairing it on the shoulder or in the parking lane, it is not absolutely safe. The driver should remain vigilant and take emergency avoidance measures immediately upon noticing any danger, moving to the safe area outside the guardrail on the shoulder. When returning to the driving lane after repairs, first accelerate on the emergency parking lane, turn on the left turn signal, and then merge into the driving lane without obstructing other normally moving vehicles.

What is the difference between high-speed motors and low-speed motors?

The differences between high-speed motors and low-speed motors are as follows: 1. Different design perspectives: From a design perspective, high-speed motors have a small rotor diameter and a large length; low-speed motors have a large rotor diameter and a small length. A smaller diameter means a relatively smaller linear speed of the rotor's outer diameter, and the centrifugal force on the embedded windings during high-speed rotation is relatively small, making them suitable for high-speed operation. Here, high-speed specifically refers to tens of thousands of revolutions, while general motors operate at a few thousand revolutions, which does not reflect this design concept. 2. Different motor power: Due to the high speed, high-speed motors have a high power density, and their volume is much smaller than that of low-speed motors, effectively saving materials. 3. Different efficiency: High-speed motors are directly connected to the prime mover, eliminating the traditional speed reduction mechanism, resulting in high transmission efficiency and low noise; low-speed motors produce more noise.

What Causes a Car to Stall?

Reasons for car stalling: 1. Electrical circuit failure - This may occur due to low-voltage power interruption during driving, causing the engine to stall. In this case, you should primarily check the ignition and starter switches as well as the fuse box; 2. Short circuit in low-voltage wiring causing stalling - This situation requires inspection of the low-voltage circuits; 3. Component failure - This issue is usually related to faults in the ignition coil, capacitor, or electronic ignition module; 4. Fuel system failure - Damage to the fuel pump, fuel line rupture, clogged carburetor fuel inlet, or empty fuel tank can cause stalling, though the car may still be restarted with difficulty in such cases; 5. Ignition system failure - Problems with the engine overheating or the anti-knock system can also lead to stalling.
