What does design speed refer to in highway design?

In highway design, the design speed refers to the maximum speed of the highway, intended to ensure safe driving for motorists. Highway regulations: Article 78: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," highways must indicate lane speeds. The maximum speed must not exceed 120 km/h, and the minimum speed must not be lower than 60 km/h. The maximum speed for small passenger vehicles 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. Posted speed limits: This refers to the speed indicated by speed limit signs and markings on the highway. The specific speed limit is determined by the transportation authorities based on the highway's design speed, functional type, geometric alignment characteristics, traffic flow, roadside environment, and other factors. Legal speed limits: On road sections without speed limit signs, drivers must adhere to the speed limits stipulated by laws and regulations, as per the "Road Traffic Safety Law" and its implementation regulations.

What does a wrench symbol on the dashboard mean?

A wrench symbol on the dashboard indicates that the car needs maintenance, not that there is a malfunction. Its primary purpose is to remind the owner to perform maintenance on the vehicle. Not all vehicles have this reminder function. For vehicles equipped with this feature, the manufacturer sets a parameter during production, and the wrench symbol will appear once the vehicle reaches a certain mileage. Typically, the maintenance interval for a car is every 5,000 to 8,000 kilometers, with the factory-set interval often exceeding 8,000 kilometers. The appearance of the wrench symbol does not affect the normal operation of the vehicle, and the symbol will disappear after maintenance is performed.

How to Detect Car Faults?

Methods for detecting car faults: Check whether the engine has difficulty starting, whether the engine is idling, whether the engine speed is stable, whether the engine temperature is too high during operation, whether the vehicle's exhaust pipe emits black or blue smoke, and whether the steering wheel is always misaligned. To diagnose faults such as the car engine failing to start, you can first check the battery, as insufficient battery power can also prevent the engine from starting. Additionally, check the ignition timing; if the timing belt slips, it will not generate an electric spark, and the engine will not start. For diagnosing faults where the vehicle's exhaust pipe emits black smoke, promptly inspect whether the choke is fully open. After turning off the engine, check whether the main nozzle of the carburetor is dripping or leaking fuel. If dripping occurs, adjust the fuel level in the float chamber and tighten or replace the main jet.

What are the types of manual transmission fluid?

Manual transmission fluid comes in six types: GL1, GL2, GL3, GL4, GL5, and GL6. Manual transmission fluid is commonly referred to as gear oil and its primary function is lubrication. Manual transmission fluid has a higher viscosity compared to automatic transmission fluid, and the replacement interval is generally shorter. Most household vehicles require manual transmission fluid replacement every 40,000 to 60,000 kilometers. Gear oil mainly refers to the lubricant used in transmissions and rear axles, differing from engine oil in terms of usage conditions, composition, and performance. Gear oil primarily serves to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for the gears.

How to Confirm the Distance Between Cars While Driving?

Methods to confirm the distance between cars while driving: 1. When the car's reflection occupies the entire rearview mirror, the distance is 3 meters; 2. When the car's reflection occupies two-thirds of the rearview mirror, the distance is 5 meters; 3. When the car's reflection occupies half of the rearview mirror, the distance is 9 meters; 4. When the car's reflection occupies one-third of the rearview mirror, the distance is 12 meters. A safe distance refers to the necessary gap maintained by the following vehicle to avoid accidental collisions with the vehicle ahead while driving. The distance between your car and the vehicle ahead can be estimated by observing the position of the rear bumper and tires of the front car through the front contour line of your vehicle. When you see the upper edge of the rear bumper of the front car, the distance is 1 meter; when you see the lower edge of the rear bumper of the front car, the distance is 2 meters; when you see the lower edge of the rear tires of the front car, the distance is 3 meters.
