What is the primary risk of blocking the left lane on a multi-lane highway?

Blocking the left lane on a multi-lane highway primarily increases the potential for tailgating from aggressive drivers. The left lane is typically designated for faster-moving traffic, and when slower vehicles occupy it, it disrupts the flow of traffic. This can lead to frustration in other drivers, particularly those who are driving at or above the speed limit. As a result, aggressive drivers may tailgate, attempting to prompt the slower vehicle to move over or create a dangerous situation by trying to pass in a more abrupt manner.

Understanding this risk underscores the importance of using lanes appropriately. Drivers should keep in mind that the left lane is meant for overtaking and faster travel, which enhances overall road safety. Managing lane usage helps maintain a smooth traffic flow and minimizes stress for all road users.
