What is the function of a deceleration lane on a highway?

• A. A lane for speeding
• B. A lane for merging
• C. An extra lane for slowing down at a highway exit
• D. A lane for passing

Answer: (C)

A deceleration lane serves a specific purpose on highways by providing an area where vehicles can safely slow down in preparation for exiting the highway. This extra lane allows drivers to decrease their speed without disrupting the flow of traffic in the main travel lanes. By facilitating a gradual reduction in speed, deceleration lanes enhance safety for both the exiting drivers and those remaining on the highway. When a driver approaches an exit, they can enter the deceleration lane to begin slowing down at a comfortable rate, minimizing the risk of abrupt stops or sudden lane changes that could endanger other motorists. This is particularly important on high-speed roadways where the differences in speed can create hazardous situations. Having a designated lane for this purpose helps to maintain traffic flow and reduces the potential for collisions that could occur if drivers were required to slow down directly in the main traffic lanes.
