Should You Downshift When Turning?

[McBarrett]

Yes. Theoretically, no matter how fast a car is going when turning, it should not roll over. The cause of rollovers is not excessive speed. For front-wheel-drive cars, rollovers during turns are mainly due to understeer, causing the front of the car to hit an obstacle on the outside, leading to a rollover. For rear-wheel-drive cars, rollovers during turns are primarily due to oversteer, causing the front of the car to hit an obstacle on the inside, resulting in a rollover. Here is some relevant information: 1. Turning speed exceeding 30 km/h: For sedans, exceeding 30 km/h in general curves is usually not a major issue. However, on sharp turns or winding roads, according to the "Road Traffic Safety Law Implementation Regulations," the speed should not exceed 30 km/h, otherwise, traffic accidents are more likely to occur. 2. Precautions: Compared to sedans, SUVs, pickup trucks, and minivans, which have a slightly higher center of gravity, are more prone to rolling over during turns. Additionally, SUVs are particularly vulnerable to frequent lane changes, as this can cause the vehicle body to sway more, increasing the risk of rollover during turns.
