Should the driver slow the vehicle in a curve or before entering the curve?

Lowering your speed before entering a curve is essential for maintaining control and ensuring safety while navigating the turn. When approaching a curve, it is important to reduce speed to a level that allows for adequate steering response and stability. A slower speed helps prevent losing traction, which can lead to skidding or overturning, especially if the curve is sharp or if road conditions are poor, such as wet or icy surfaces.

Slowing down ahead of the curve allows drivers to assess the curve's radius, the road conditions, and any potential obstacles. It also gives drivers a chance to adjust their steering input effectively, helping to maintain their lane and avoid oversteering or understeering.

Increasing speed while in the curve can lead to a loss of control, particularly if the vehicle cannot handle the centrifugal forces acting on it, while maintaining the same speed may be inappropriate if that speed is too high for the curve's geometry. Only slowing down after entering the curve may be too late, as it could result in an inability to navigate the turn safely, increasing the risk of accidents.
