Final answer:
Expressway entrances that come in from the left instead of the usual right present special problems for drivers. They require drivers to navigate across multiple lanes of traffic and can lead to confusion and potentially dangerous situations.
Step-by-step explanation:
Expressway entrances that come in from the left instead of the usual right present special problems for several reasons. One main reason is that drivers are not accustomed to this pattern and may be caught off guard, leading to confusion and potentially dangerous situations. Additionally, these left-side entrances require drivers to navigate across multiple lanes of traffic, which can increase the risk of accidents.
For example, if a driver wants to enter an expressway from the left, they would have to cross several lanes of fast-moving traffic to reach the desired lane. This maneuver can be challenging for drivers, especially if they are not experienced or confident in merging across multiple lanes.
Overall, these left-side expressway entrances require careful attention and skill from drivers to safely navigate the highway traffic and merge into the correct lane.
