15cm-high curbs can be navigated by vehicles with ground clearance exceeding 150mm. Below are relevant driving precautions: 1. Strictly observe traffic regulations: According to transportation authorities, over 80% of traffic accidents result from violations. Traffic rules embody lessons learned through predecessors' experiences - compliance being the foremost consideration for novice drivers to minimize accident risks. 2. Maintain proper steering control: Fundamental driving principles include mastering five essential operations: starting, stopping, turning, gear shifting, and braking.

As a seasoned driver with over 30 years of experience, I know that the ground clearance of sedans typically ranges between 15 to 20 centimeters. A 15-centimeter curb might sound low, but while it might barely pass when the car is unloaded, it will likely scrape the undercarriage when fully loaded. I remember one time when I was in a hurry and tried to rush over a small slope—only to hear a loud 'clunk' as the underbody panel got dented. The repair cost me nearly a thousand bucks and compromised safety. In daily driving, this risk is too high—wheel rims can deform, and tire sidewalls can crack. I recommend that drivers first step out to visually estimate the height or use a tape measure if needed. Sedan chassis aren’t as sturdy as those of off-road vehicles, so it’s better to detour when possible. Regular should include checking the suspension system to minimize the chances of accidents.

Having worked in the vehicle repair industry for so many years, I've seen numerous clients damage their cars by forcing them over curbs. A 15 cm height is a challenge for sedans, as most standard models have a minimum ground clearance of around 15 cm. For example, common family cars like the Corolla or Honda Civic are designed with their chassis close to the ground, and forcing them over can damage the suspension or exhaust pipes. After testing many vehicles, I've found that even new tires can suffer sidewall blowouts, with repair costs ranging from a few hundred to tens of thousands. I recommend first checking the clearance data in the owner's manual or using a smartphone measuring tool to gauge the actual height—safety comes first.

When I was younger, I also enjoyed taking risks while driving. One night, trying to take a shortcut, I attempted to drive over a 15 cm high curb. The result was a screeching sound from the undercarriage, and the next day, I noticed slight deformation in the wheel hub. The ground clearance of ordinary sedans is usually no more than 20 cm, so 15 cm is already close to the limit. Driving slightly faster could lead to loss of control. Experience has taught me that such attempts have little chance of success and are likely to damage the car and cost money. Next time, try using your palm to gauge the height—place your palm on the curb, and if there's not enough clearance under the car, don't take the risk.

From a driving safety perspective, I strongly oppose sedans attempting to mount curbs higher than 15cm. It's too high - most sedan ground clearances are around 15cm. Forced attempts may cause minor component scratches at best, or severe suspension damage at worst, potentially leading to skidding accidents. I've witnessed real cases where vehicles leaked oil and stalled mid-road due to this. Recommend drivers avoid such maneuvers, prioritizing proper roads or using temporary ramps when necessary. Regular checks of tire and undercarriage scrape resistance can mitigate risks.

As an ordinary office worker, I usually commute by car and prefer to avoid high obstacles. Most sedans can't handle curbs over 15 cm, as their ground clearance is typically 15-20 cm, but that's at the lowest point. I've tried a few times and almost damaged the exhaust pipe. It's best to get out and visually check the height, or use a small object like a next to the wheel. If you must go over, slow down to almost zero speed, but the risk remains high - it's better to choose an alternative route for peace of mind.
