Which trio describes the three components that contribute to a collision?

• A. Driver, Vehicle, Roadway
• B. Driver, Weather, Roadway
• C. Vehicle, Roadway, Traffic
• D. Driver, Vehicle, Weather

Answer: (A)

A fundamental idea in crash causation is that collisions arise from the interaction of the driver, the vehicle, and the roadway. The driver’s choices and attention shape how the vehicle is used, the vehicle’s condition affects how it responds to inputs or emergencies, and the roadway environment—including surface conditions, geometry, and lighting—affects traction and visibility. Weather influences roadway safety but is not treated as its own separate component in this standard model; it’s part of the roadway conditions. That’s why Driver, Vehicle, and Roadway is the best description of the three interacting factors that contribute to a collision.
