A driver on the TP HCM - Long Thanh - Dau Giay Expressway faces a challenge when attempting to yield the left lane for faster traffic. The expressway features two lanes: the left lane has a maximum speed limit of 90 km/h, while the right lane is limited to 70 km/h. This speed differential creates a dilemma for drivers trying to follow road etiquette.

If a driver, traveling at the maximum speed of 90 km/h in the left lane, wishes to move to the right lane to allow faster vehicles to pass, they are legally required to reduce their speed to 70 km/h. This necessitates decelerating before changing lanes, which poses a significant risk of a rear-end collision from other vehicles also traveling at 90 km/h.

Conversely, if the driver maintains 90 km/h while moving into the right lane, they would be exceeding that lane's speed limit by 20 km/h, resulting in a traffic violation.

The driver expresses a strong desire to yield, but finds both options problematic and illogical under the current lane speed regulations. This system of speed-based lane division appears to hinder the ability to safely and legally yield on the expressway.
