To safely negotiate a curve, use your brakes before you enter the curve. You should always lower your speed before entering a curve. Because of centrifugal force, there is a strong outward pull on your vehicle.
Reduce speed before entering the curve, and slowly lighten the pressure on the brake until reaching the apex point (where the car is closest to the inside of the curve line). At the apex or exit point, apply light acceleration to pull the car out of the curve.
