Why is lane splitting not allowed in Iowa?

Lane splitting, which involves riding a motorcycle between lanes of slow-moving or stopped traffic, is not permitted in Iowa primarily because it increases the risk of accidents and is considered unsafe. This practice can create unpredictable situations for both motorcyclists and other drivers. When a motorcyclist maneuvers between vehicles, it can lead to close encounters where the motorcyclist may not be seen by drivers who are only focusing on the road ahead.

Furthermore, lane splitting can result in a higher likelihood of collisions due to the reduced reaction time for both motorcyclists and other vehicles. In a state like Iowa, where traffic laws prioritize safety, the prohibition of lane splitting is a preventive measure intended to protect all road users. By restricting this practice, Iowa aims to minimize the risk of accidents that could occur in situations where visibility and awareness are compromised.

The other options do not accurately represent the primary concerns associated with lane splitting, as the focus in lawmaking tends to prioritize safety over traffic flow improvements or convenience.
