A route includes a steep hill, a roundabout at the bottom, and a high centre-of-gravity load. What is the safest planning answer?

1. Control speed before the descent, preserve brakes, approach the roundabout slowly, and steer smoothly
2. Let the lorry accelerate downhill and brake in the roundabout
3. Choose a higher gear to increase speed before the turn
4. Rely on the load straps to prevent rollover
