Left-side expressway entrances present special problems because which traffic in the left lane is typically the fastest?

• A. The left lane is usually used for highest speed
• B. The left lane has more exits
• C. The left entrance merges more quickly
• D. The left lane is narrower

Answer: (A)

Left-side entrances are tricky because the traffic in the leftmost lane on expressways is usually the fastest, reserved for passing and higher speeds. When you enter from the left, you’re merging into vehicles that are already moving quickly, which means gaps between cars are small and disappear more quickly. To merge safely, you need to accelerate to match the speed of traffic and find a workable gap, signaling early and weaving smoothly into the flow without forcing others to slow or swerve. This faster, more aggressive traffic in the left lane is what makes left-side entrances require extra caution.
