What lane must i use on the expressway if driving alone in rush hour?

If you're driving alone during rush hour on an expressway, you should typically use the rightmost lane, as this lane is designed for regular traffic and slower vehicles. The left lanes are generally reserved for faster-moving traffic and passing. However, it's essential to follow local traffic laws and any posted signs, as regulations may vary by location. Always ensure you're driving safely and remain aware of your surroundings.
