What should a motorcyclist do when their rear tire blows out?

Answer: C — Keep a steady throttle and steer straight.

When a rear tire blows out while riding a motorcycle, the recommended action is to keep a steady throttle and steer straight. This is crucial because accelerating or braking abruptly can upset the balance of the motorcycle, making it more difficult to control. The rear tire is critical for maintaining stability, and when it fails, the motorcycle may start to sway or behave unpredictably. By maintaining a steady throttle, a rider can help stabilize the bike, allowing them to steer straight and avoid sudden movements that could result in losing control. It is also important to keep an even grip on the handlebars to further enhance stability. Once the rider has gained control, they can begin to slow down gradually and safely maneuver to the side of the road. Pulling over immediately or braking firmly could increase the risk of losing balance, especially with a blown rear tire, which is why maintaining a steady throttle is key in managing the situation effectively.
