Motorcycles often appear to go under trucks in traffic due to a phenomenon called "lane filtering" or "lane splitting." Lane filtering refers to the practice of a motorcycle rider maneuvering between lanes of slower-moving or stopped vehicles, including trucks, in order to bypass traffic congestion. This is typically done when the space between the lanes is wide enough for the motorcycle to safely pass through.
There are several reasons why motorcycles engage in lane filtering:
Traffic congestion: Motorcycles are smaller and more agile than cars and trucks, allowing them to navigate through traffic more easily. By filtering between lanes, motorcyclists can take advantage of the available space and move ahead, saving time and avoiding long delays.
Heat management: Motorcycles tend to generate a significant amount of heat, especially in slow-moving or stationary traffic. Riding between lanes allows the motorcycle to receive more airflow, which helps in cooling the engine and the rider, particularly in hot weather conditions.
Safety considerations: Contrary to popular belief, lane filtering, when done responsibly and within legal limits, can enhance motorcycle safety. Staying in between lanes can reduce the risk of rear-end collisions, as motorcycles are more visible to other drivers, and it provides an escape route in case of an emergency.
It's important to note that the permissibility of lane filtering varies by jurisdiction. Some countries and states have specific laws that allow or regulate lane filtering, while others prohibit or have ambiguous regulations regarding the practice. Motorcyclists should always be aware of the local laws and exercise caution when lane filtering to ensure their own safety and the safety of others on the road.
