What should be your first priority before braking when following a car around a curve that suddenly slows?

When approaching a curve and noticing that the vehicle ahead is suddenly slowing down, your first priority should be to get your motorcycle upright. This is crucial because a motorcycle is designed to be ridden while it's leaned over in a turn, but it is much more stable and controllable when it is upright. If you brake while leaning, it could cause the tires to lose grip, leading to a potential loss of control and crash.

By bringing your motorcycle to an upright position before braking, you ensure that you maintain optimal traction and handling. This approach allows for safer and more effective braking as you respond to the slowing car, minimizing the risk of skidding or tipping over. The remaining options, like applying the brakes immediately or looking for another lane, do not prioritize control and stability in the curves, which are essential to safely maneuvering your motorcycle.
