If you are driving slower than other traffic on an interstate, which lane should you use?

When driving slower than other traffic on an interstate, the appropriate lane to use is the right lane. This practice is established to ensure smoother traffic flow and to allow faster vehicles the ability to pass safely. The right lane is typically designated for slower-moving vehicles, and using it prevents potential hazards that could occur if slower drivers remain in the left or middle lanes, which are usually reserved for overtaking and faster vehicles.

On an interstate, the left lane is typically reserved for passing and should be used by vehicles traveling at or above the speed limit. Consequently, remaining in the left lane when driving slower than surrounding traffic could lead to frustration among other drivers, resulting in unsafe situations.

The middle lane generally serves as a transitional lane and is best suited for vehicles moving at or near the average speed of traffic. The emergency lane is intended for vehicles that are experiencing mechanical failures or emergencies and should not be used for regular driving.

Choosing the right lane when moving slower than surrounding traffic is an important aspect of safe interstate driving and helps to maintain overall traffic efficiency.
