In urban roads, each lane is 3.5 meters wide. At intersections, diversion lanes are 2.3-2.5 meters per lane. On highways, each lane is 3.75 meters wide, and emergency stopping lanes are 1.5-2.5 meters wide. Here are some precautions for driving: 1. Vehicle inspection before departure: Conduct a comprehensive check of the vehicle daily before setting off, including checking for oil or water leaks; measure tire pressure to ensure it is appropriate; inspect the engine oil condition; and verify the spare tire is intact. 2. Be cautious when wading: If encountering waterlogged roads, assess the water depth and road conditions beneath the water to determine if it exceeds the vehicle's capability. Avoid attempting to wade if the water depth exceeds half the height of the car's tires.

In my 20-30 years of driving experience, the issue of lane width is definitely worth discussing. Standard lanes on urban roads are typically 3.5 to 3.7 meters wide, allowing regular cars and SUVs to pass through steadily and avoid scratches. Highways have wider lanes, generally around 3.7 to 4.3 meters, since higher speeds require more space for sharp turns or emergency lane changes. I often drive long distances and notice that rural road lanes can narrow down to just over 3 meters, requiring extra caution for blind spots at night. Wider lanes increase safety margins, especially as vehicles are being built larger nowadays—narrow lanes can easily lead to accidents, particularly in rainy or snowy conditions. Additionally, bus lanes or special-purpose lanes may exceed standard widths, with designs accounting for vehicle dimensions and traffic flow variations. This knowledge is quite helpful for daily route selection while driving.

Right after getting my driver's license, my instructor repeatedly emphasized the importance of lane width. He told me that standard urban lanes range between 3.5 to 3.7 meters, and as a beginner, I should avoid driving too close to the edge since visual misjudgment could easily lead to crossing the line and penalty points. Highways are more generous, with lanes about 4 meters wide, making lane-changing practice less stressful during driving lessons. Practicing at the training ground, I felt secure driving a car only 1.8 meters wide on such lanes. Lane width varies due to multiple factors; for instance, older urban areas might have lanes narrowed to under 3 meters due to building constraints, while newly developed areas offer much wider lanes. It's crucial to constantly observe roadside signs while driving. Understanding these aspects can reduce collision risks, especially when parking—choosing the right spot makes it less likely to scratch other cars.

As a parent, lane width worries me about my child's safety. Standard lanes of 3.5 to 3.7 meters may seem wide enough, but when cycling on sidewalks or crossing roads after school, insufficient width becomes hazardous. I've noticed that narrow sections often have blind spots, increasing the risk of children darting out suddenly. In contrast, wider lanes like those over 4 meters on highways offer better buffer space. Wider lanes also facilitate emergency stops, such as during a tire blowout without blocking the entire road. Sometimes, road designs cut corners, and narrow lanes pose many hidden dangers. I call for stricter regulations to ensure pedestrian safety. Understanding lane width helps in choosing safer routes and keeping children away from sharp turns while playing.
