Final answer:
A deceleration lane is an extra lane at the highway exit where vehicles can slow down safely. It helps maintain the smooth flow of traffic on the highway. Deceleration refers to any decrease in speed, while negative acceleration is specific to the direction of the current velocity and may not always result in slowing down. option a is correct.
Step-by-step explanation:
A deceleration lane is an area of the road designed to allow vehicles to slow down safely. It is typically found on highways and is used by drivers when exiting onto off-ramps or service areas. The purpose of these lanes is to minimize disruption to the flow of traffic on the main highway by providing a separate lane where vehicles can reduce speed without affecting the vehicles traveling at highway speeds.
The correct option for the definition of a deceleration lane is option a: An extra lane at the highway exit. This lane provides the space needed for vehicles to decelerate safely without interfering with the traffic still moving at higher speeds on the highway. It is important to understand the difference between deceleration and negative acceleration to drive safely and effectively. Deceleration refers to any decrease in speed, while negative acceleration refers to acceleration in a direction opposite to the current velocity of the vehicle.
To clarify the provided tip and MISCONCEPTION ALERT, when you are in a deceleration lane and slowing down, you are indeed decelerating, and it could also be considered negative acceleration if you are taking your frame of reference along the direction of motion of the car. Regarding the question about the rabbit, we can't guarantee its safety just because the car is in the furthest lane; other factors like traffic in the other lanes and the rabbit's behavior also play a role.
