How much wind force will it take to roll over a tractor trailer?

It depends on several factors, including the size and weight of the tractor-trailer, the wind speed, and the direction of the wind. Generally, it takes wind speeds of at least 65 miles per hour (105 km/h) to roll over a tractor-trailer. However, a weaker wind can also cause a tractor-trailer to roll over if it is empty or has a high center of gravity.

In addition, the direction of the wind can also play a role. A wind that blows perpendicular to the long axis of the tractor-trailer is more likely to cause it to roll over than a wind that blows parallel to the long axis.

To reduce the risk of tractor-trailers being overturned by wind, drivers should be aware of the weather forecast and avoid driving in high-wind conditions. They should also slow down and be prepared to brake suddenly if they encounter strong winds. Additionally, drivers should avoid driving empty or overloaded trucks and should secure any loose cargo.
