Can vehicles drive on an 8 cm thick road surface?

An 8 cm thick concrete road surface is relatively thin and can only accommodate light vehicles; it is not recommended for heavy-duty vehicles as they can easily damage the road. Below are more details about situations that can easily damage road surfaces: 1. Overloaded trucks damaging the road: Generally, vehicles have a specified load-bearing index. This regulation is established by manufacturers based on considerations of highway surface load-bearing capacity, calculated carefully to provide the index. Overloaded trucks are significantly heavier and particularly prone to damaging road surfaces. 2. Major traffic accident impacts: Major traffic accidents can also easily lead to road surface damage. For example, if a vehicle is hit and thrown onto the road surface, it can directly cause the road to be crushed.

When I saw this question, what came to my mind was whether an 8 cm high road bump can be driven over. I've encountered similar situations before while driving. The ground clearance of ordinary sedans is usually around 10 to 15 cm, so most vehicles can barely pass over an 8 cm bump, but extra caution is needed. Driving slowly at low speed is crucial, otherwise wheel slippage or undercarriage scraping could occur. It's advisable to first get out of the car to observe the actual height and slope of the road surface, ensuring there are no obstacles like gravel affecting passage. Remember to check that your tire pressure is normal, and don't overlook your vehicle's ground clearance—different models like SUVs have better passing capability. Safety first—if you sense any risk, it's better to detour or seek professional assistance. During regular maintenance, frequently inspect the undercarriage to prevent dust accumulation from affecting passing performance.

I often commute by car and pay extra attention to 8cm-high road obstacles. Ordinary vehicles like family sedans or compact cars can generally pass, but the speed must be reduced to a crawl to avoid excessive jolts or damage to the suspension system. In practice, I slow down to below 5km/h, turn off the AC to reduce load, and gently steer through. Wet road conditions also require consideration, as reduced tire grip increases the risk of slipping. Older vehicles or those carrying heavy loads face greater difficulty. It's a good habit to inspect uneven road surfaces beforehand—checking for standing water or debris to prevent accidents. Regular vehicle inspections also help minimize such issues.

Having driven for several years, I feel that an 8cm road bump can usually be passed. The key lies in vehicle selection and driving style. Sedans generally have a ground clearance of over 10cm, so just drive slowly and steadily without rushing. Related factors include maintaining proper tire pressure to improve passability and not neglecting regular chassis cleaning. If it feels unstable, it's more reassuring to choose an alternative route.
