What should you check before riding in traffic?

Answer: B — Check for blind spots and other vehicles

Before riding in traffic, it's essential to check for blind spots and other vehicles because this directly impacts your safety as a rider. Being aware of your surroundings, including the positions of other vehicles, is crucial for making informed decisions on the road. Blind spots can be areas around your motorcycle that are not visible in your mirrors; ensuring you look around and use your mirrors helps you to avoid potential collisions and allows you to assess the flow of traffic effectively. While checking the weather forecast or your fuel level might seem relevant, they do not address immediate safety concerns when interacting with traffic. The color of your motorcycle is also not a critical factor for safe riding; awareness of your environment is far more important in preventing accidents and ensuring a smooth ride.
