What is the purpose of carpool lanes?

1. To allow single drivers to travel faster

2. To promote carpooling and reduce traffic congestion

3. To designate areas for parking

4. To create additional lanes for trucks

The correct answer is: To promote carpooling and reduce traffic congestion

The purpose of carpool lanes is to promote carpooling and reduce traffic congestion. These lanes are designed specifically for vehicles that carry multiple passengers, encouraging drivers to share rides rather than driving alone. By incentivizing carpooling, these lanes help decrease the overall number of vehicles on the road, which can lead to reduced traffic delays and lower greenhouse gas emissions. The presence of carpool lanes can also make travel faster for those participating in carpools, as they often have less congestion compared to regular lanes. This initiative aims to enhance public transport and optimize road space usage.
