According to regulations, the maximum slope of a fire lane should not exceed 8%. Below are specific requirements regarding fire lanes: 1. Requirements for dedicated fire truck access: In accordance with national laws and regulations, newly constructed buildings should reserve dedicated fire lanes to ensure unobstructed evacuation routes, safety exits, and fire truck access. Roads within blocks should consider fire truck passage, with the distance between road centerlines preferably not exceeding 160.0m. When the length of a building along a street exceeds 150.0m or the total length exceeds 220.0m, a fire lane passing through the building should be established. If this proves difficult, a circular fire lane should be constructed. For buildings with enclosed courtyards or atriums, if the short side length exceeds 24.0m, a fire lane entering the courtyard or atrium should be established. 2. Supplementary provisions: When the slope between a site's vehicle lane and a city road is significant, a buffer section should be installed without occupying city road space; in particularly challenging areas with steep terrain, the road gradient should not exceed 11%, with the slope length limited to 100m, and anti-skid measures should be implemented on the road surface.

Is it safe to charge at an outdoor charging station in the rain?

Charging at an outdoor charging station in the rain is very safe. Here is relevant information: 1. Charging port standards: Manufacturers have strict standards for charging components and interfaces, generally achieving IPX6-IPX7 waterproof ratings. This means that under light rain conditions, there will be no damage to components or safety issues. 2. Parking position: When parking, try to choose a higher ground position. If parked in a low-lying area, prolonged water accumulation may cause the battery or charging port to be submerged in water. Before charging, check the charging gun to ensure there is no accumulated water or debris inside, and make sure the charging gun and charging port can fully contact for normal charging.

What is the Difference Between Passenger Liability Insurance and Driver & Passenger Accident Insurance?

Passenger Liability Insurance and Driver & Passenger Accident Insurance differ in the following aspects: 1. Different Definitions: Passenger Liability Insurance is purchased per seat, while Driver & Passenger Accident Insurance is divided into two types—"per person" and "per vehicle." 2. Different Insurance Coverages: Passenger Liability Insurance is a liability insurance, meaning compensation is only provided if the driver is at fault in an accident, resulting in bodily injury to passengers. Driver & Passenger Accident Insurance (per vehicle) is an accident insurance, covering all passengers in the vehicle regardless of who is at fault. 3. Different Compensation Ratios: Passenger Liability Insurance compensates based on the proportion of liability—100% for full liability, 70% for primary liability, 50% for secondary liability, 30% for equal liability, and no compensation if not at fault. Driver & Passenger Accident Insurance pays the agreed insured amount regardless of fault, as per the policy terms.

What is the definition and function of wheel toe-in?

Wheel toe-in is defined and functions as follows: 1. Definition: Wheel toe-in refers to the condition where the front edges of the two front wheels are closer together than the rear edges. The difference in distance is called the toe-in value. 2. Functions: (1) Counteracting the effects of wheel camber: Toe-in creates a tendency for the wheels to turn inward, which can offset the adverse effects caused by wheel camber, allowing the wheels to roll straight without lateral skidding, thereby reducing tire wear. (2) Compensating for suspension system deformation: The deformation of the suspension system's pivot points also creates a tendency for the front wheels to turn outward, which needs to be compensated for by toe-in. (3) Facilitating steering: The main purpose of wheel camber is to make steering easier, keeping the wheels close to the inner wheel hub bearings to reduce the load on the outer bearings and wheel hub nuts, contributing to safer driving.

What do the front and rear buttons in the car mean?

Front button is for front window defogging, Rear button is for rear window defrosting. Here is some related information: 1. Principle: The principle of the rear windshield defogging device is to embed copper wires in the rear windshield. When there is moisture or fog on the rear windshield, an electric current heats up some of the copper wires. This heats the windshield and removes the fog. 2. Rear: The literal meaning of rear is the back or rear part. The rear button in the car is usually located on the air conditioning control panel. It is actually the rear windshield defogger switch button. However, many car models now omit the 'rear' text and simply use a square box with an upward wavy line icon.

How Long Can a Car Run After the Last Fuel Bar Disappears?

How long a car can run after running out of fuel varies. Some can travel 120-160 kilometers, while others may only manage 30-60 kilometers. The fuel gauge warning light may be inaccurate due to fuel sloshing in the tank on bumpy roads. Additionally, fuel consumption is not a fixed parameter and is influenced by various factors. In such cases, it is essential to find the nearest gas station promptly. The remaining mileage differs based on the vehicle model, road conditions, and fuel consumption: 1. Highway: When the fuel light comes on under highway conditions, the remaining mileage is approximately 120-160 kilometers; 2. Mixed: Under mixed road conditions, the remaining mileage is about 80-120 kilometers when the fuel light comes on; 3. Congested: In congested road conditions, the remaining mileage is roughly 30-60 kilometers when the fuel light comes on.

How are vehicle wading levels classified?

The six levels of waterlogged vehicles are as follows: 1. Just reaching the vehicle chassis: The water just reaches the vehicle chassis, and the vehicle floor may become damp, but the likelihood of significant water ingress is low, with minimal impact on the electrical equipment inside the vehicle. 2. Halfway up the wheels: The water reaches halfway up the wheels. Due to the vehicle's incomplete sealing, water will begin to enter the interior. For lower-bodied sedans, the water level inside may affect the seat adjustment motors and electrical components such as heating and ventilation. 3. Completely submerging the tires: The water almost completely submerges the tires. At this point, the water level inside the vehicle will fully submerge the seat cushions and the central armrest area, affecting a large number of electrical devices. 4. Reaching the engine hood: The water reaches the engine hood, and the water level inside the vehicle rises to the dashboard. Additionally, the headlights and the engine intake pipe in the engine compartment begin to take in water. 5. Submerging the engine hood: The water completely submerges the engine hood, and at this stage, almost all electrical equipment inside the vehicle will be affected by the water. 6. Submerging the roof: The water submerges the roof, affecting the vehicle's headliner and sunroof module, with no component inside the vehicle spared.
