Chain Reaction
One event triggers a series of crashes — each participant's reaction creates a new hazard.
What is it
A chain reaction is when one road event triggers a cascade of crashes. The first car brakes, the second hits it, the third hits the second. For a motorcyclist caught in a chain reaction, the danger is extreme.
How it happens
Someone brakes hard or swerves. Vehicles around begin maneuvering, braking, dodging. Each reaction creates a new hazard. A rider traveling in traffic can be pinched, rear-ended, or forced to swerve with nowhere to go.
How to reduce the risk
- Maintain distance — not just ahead, but to the sides as well
- Watch 2-3 cars ahead, not just the one in front
- In heavy traffic — keep covering the brake and plan an escape route
- Don't ride in the pack — stay at the edges where you have maneuvering room
