Driving slow in the left lane is not only a pain but it is also dangerous. Driving in the right lane and keeping the left lane open for passing allows traffic to flow smoothly and reduces accidents. Other benefits include less road rage, better gas mileage, less stress, and getting to the destination faster.
Some mistakenly believe driving slowly in the left lane keeps everyone safe. In reality it drastically increases the risk of accidents. The research shows that slowing down and changing lanes multiple times can be far more dangerous than speeding, causing almost 10 percent of the total accidents on highways.
We can all make the roadways safer by cruising in the right lane and keeping left lane for passing. Please practice lane courtesy.
