Car speed limit on mountain roads is 30 kilometers per hour. On roads with speed limit signs, you must drive according to the speed limit signs. Below are the relevant regulations on car speed limit driving: Roads without a central line: Urban roads have a speed limit of 30 kilometers per hour; highways have a speed limit of 40 kilometers per hour. Roads with only one motor vehicle lane in the same direction: Urban roads have a speed limit of 50 kilometers per hour; highways have a speed limit of 70 kilometers per hour. Roads with two lanes in the same direction: The minimum speed for the left lane is 100 kilometers per hour; the minimum speed for the right lane is 60 kilometers per hour. Roads with three or more lanes in the same direction: The minimum speed for the leftmost lane is 110 kilometers per hour; the minimum speed for the middle lane is 90 kilometers per hour; vehicles traveling at speeds above 60 km/h but below 90 km/h should drive in the rightmost lane.

I often drive on mountain roads, so I have some insights on speed limits. Generally, the speed limit on mountain roads isn't fixed, usually ranging between 30 to 60 kilometers per hour, depending on road conditions. For example, if there are many curves, the limit might be 30 or 40, while straight sections could allow 50 or 60. I remember on a steep slope, the speed limit dropped to 40 because it was rainy and slippery. Safety comes first on mountain roads—driving slower gives better control, especially in sharp turns where accelerating could cause skidding. Beginners should start at lower speeds and observe changing road signs, as some areas adjust limits based on weather. Navigation apps can give rough speed limit estimates, but don't rely solely on them—always check actual signs for reliability. Also, reducing speed by 20 km/h or more in poor conditions is safer. In short, mountain road speed limits are flexible—driving slower lets you enjoy the scenery while staying safe.

After driving for so many years, I pay special attention to safety regarding speed limits on mountain roads. The general speed limit on mountain roads is around 40 to 50 kilometers per hour, but it's not absolute—some sharp curves may have a limit as low as 30. The reason is simple: mountain roads are bumpy, and high speeds can easily lead to loss of control or skidding. I once drove on a road with a 50 km/h limit, but after rain, it was reduced to 40 to prevent accidents. The key is to pay attention to traffic signs, as they indicate the exact speed limits—don’t ignore them. My experience driving on mountain roads tells me not to release the throttle too quickly when going downhill to avoid overheating the brakes. I recommend installing a speed limit reminder device for assistance, but don’t rely solely on technology. Actual road conditions, such as fog or low visibility, may require even lower speeds. Regularly check tire conditions to maintain grip. Navigation tools sometimes update speed limit information, but they’re not always accurate—safe driving without rushing is the golden rule.

How to Adjust a Misaligned Steering Wheel?

Adjusting a misaligned steering wheel requires a wheel alignment. Below are the relevant details for adjusting the steering wheel: Introduction to Adjusting the Tie Rod: This is a crucial component in a vehicle's steering mechanism, directly affecting the stability of vehicle handling, operational safety, and the lifespan of the tires. If the tie rod becomes uneven in length, it will cause the vehicle to pull towards the longer side. Adjusting the Length of the Tie Rod: This does not involve "cutting" or "extending" but rather "screwing in" or "screwing out" the tie rod base. First, prepare a wrench, then turn the vehicle's steering wheel all the way to the right to expose the rear of the left front wheel. Use the wrench to loosen the fastening nut, then rotate the left tie rod clockwise. Clockwise rotation refers to the position of the tie rod relative to its base; "screwing in" the left tie rod means shortening it.

Why are Audi's headlights so bright?

Audi's headlights are matrix headlights, which is why they are relatively bright. Here is an introduction to matrix headlights: High level of intelligence: Matrix headlights are brighter and more intelligent. The headlights can recognize pedestrians and vehicles. Smart adjustment based on pedestrians: Intelligent automatic headlights can automatically adjust the illumination angle after recognizing pedestrians, only illuminating the lower body of pedestrians. This avoids dazzling the pedestrians' eyes while ensuring that the driver can see them. Recognize vehicles to reduce accidents: Intelligent automatic headlights can recognize moving vehicles and parked vehicles on the roadside. If these headlights detect an oncoming vehicle, they will automatically adjust the illumination angle to avoid dazzling the oncoming driver's eyes.

What Causes a Car to Start and Then Stall?

A car starting and then stalling is often caused by a faulty idle motor or a dirty throttle body leading to clogged idle ports. Below are the solutions and potential hazards: Solutions: Clean the throttle body and fuel injectors, replace the fuel filter, check if the spark plugs are heavily carbon-fouled or have excessive gaps, and verify if there is insufficient fuel pressure or clogged fuel injectors. Also, clean the fuel pump's filter screen. Hazards of Stalling: Each time the engine stalls, the engine oil flows back into the oil pan. Upon restarting, the crankshaft and crankshaft bearings lack sufficient lubrication, resulting in metal-to-metal friction, which can shorten the engine's lifespan. Frequent stalling can significantly impact the vehicle's performance and longevity.
