How should a rider react if their motorcycle begins to weave over rain grooves?

Maintaining a steady speed while riding straight across rain grooves is the safest response when a motorcycle begins to weave. Rain grooves are often found on highways to help with water drainage but can create a sensation of instability for riders, especially at higher speeds. By keeping a consistent speed and steering straight, the rider can maintain control, allowing the motorcycle to navigate the grooves without excessive movement or loss of balance. Abrupt changes in speed or steering, such as panicking or overcorrecting, can lead to a loss of control, whereas reducing speed while still maintaining a straight line is the best way to stabilize the ride. Adjusting tire pressure may be a consideration for general maintenance, but it is not an immediate corrective action in this situation.
