What is the proper technique for driving on a curve?

1. Accelerate through the curve to maintain momentum and reduce travel time
2. Reduce speed before the curve, maintain steady speed through it, and accelerate gently when exiting
3. Brake hard in the middle of the curve when the vehicle begins to drift outward
4. Stay at the same speed throughout the curve regardless of posted advisory signs — slow before curves, hold steady through them, then accelerate gently out.
