Explanation:

Analyze communication on the roadway

The first question asks for the best way to send and receive messages to and from other roadway users. In Defensive Driving and Traffic Safety, communication is key to preventing conflicts. Drivers communicate intentions using vehicle equipment like turn signals, headlights, hazard lights, and the horn. Speeding up, calling on a cell phone, or taking another route are not standard or safe methods of active communication.

Analyze under-inflated tire grip

The second question asks which part of an under-inflated tire grips the road well. When a tire is under-inflated, it lacks the air pressure needed to keep the center of the tread firmly against the road. As a result, the tire sags in the middle, shifting the vehicle's weight to the outer edges. Therefore, only the outside edges of the tire tread grip the road well.

Define energy of motion

The third question asks for another way of expressing "energy of motion." In physics and traffic safety, the energy an object possesses due to its motion is defined as kinetic energy. This energy increases with the square of the vehicle's speed and directly impacts stopping distances.
