The hidden part of a corner
Choose a speed that leaves time to react to an obstacle just beyond the limit of your view.
Choose speed for the road you can see
When a corner blocks your view, do not assume the hidden part of the road is clear.
What blocks the view?
Trees, a slope, a building, or a car ahead can obscure the road. Note how far you can see the asphalt and what prevents you from seeing farther.
How much road is visible?
Watch how far the visible stretch extends. If its far edge is approaching quickly, you have less and less time to react to a car, pothole, or mud just around the corner.
The visible stretch must leave time to react
You need enough room before the limit of your view to notice an obstacle and brake or change your line. If there is not enough room, your speed is too high.
Entry speed
Reduce speed in advance, before entering the corner. When you are leaned over and visibility is restricted, you have less margin for braking and changing your line.
At the corner exit
When you can see further down the road and it is clear ahead, you can roll on the throttle smoothly.
Late braking leaves fewer options
When you have to slow while already leaned over, the tires must handle cornering and braking at the same time. It is better to finish most of your deceleration before leaning significantly.
A familiar corner
Do not accelerate just because a familiar corner is usually clear. Choose your speed for the road you can see now: a parked car or overgrown bushes may have changed the view.
