No, it is not illegal to drive beside a motorcycle in the same lane; however, specific practices such as lane sharing and lane splitting have varying legal statuses across different states.
Understanding Lane Sharing and Lane Splitting

- Lane Sharing: This occurs when two motorcycles ride side by side or in a staggered formation within the same lane. Many states permit this practice among motorcyclists, recognizing it as a safe and efficient use of road space. However, lane sharing between a motorcycle and a car is generally discouraged due to safety concerns.
- Lane Splitting: This involves a motorcycle riding between lanes of slow-moving or stopped traffic, effectively creating a new lane between vehicles. The legality of lane splitting varies by state, with some allowing it under specific conditions and others prohibiting it entirely.
State-Specific Regulations
- California: California is the only state that explicitly permits lane splitting. The California Highway Patrol provides guidelines to ensure it is done safely, such as not exceeding 10 mph faster than surrounding traffic and avoiding the practice when traffic is moving above 30 mph.
- Arizona, Utah, Montana, and Hawaii: These states allow variations of lane filtering, a practice similar to lane splitting but typically occurring at lower speeds and under specific conditions. For example, in Utah, lane filtering is permitted when traffic is stopped, and the motorcyclist does not exceed 15 mph.
- Other States: In states like Georgia, New York, Pennsylvania, and Virginia, lane splitting is explicitly prohibited. Motorcyclists are required to operate within a single lane and are not allowed to pass between lanes of traffic.
Safety Considerations
Driving beside a motorcycle within the same lane can be hazardous. Motorcycles require the full width of the lane to maneuver safely, avoid road hazards, and maintain visibility. Sharing a lane with a car can limit a motorcyclist’s ability to react to sudden changes, increasing the risk of collisions.
Legal Implications
While it may not be illegal to drive beside a motorcycle in the same lane in some jurisdictions, doing so can lead to citations for unsafe driving practices. Law enforcement officers may interpret such actions as reckless or negligent, especially if they result in accidents or impede traffic flow.
Recommendations for Drivers
- Avoid Lane Sharing with Motorcycles: Allow motorcycles the full use of their lane to ensure their safety and yours.
- Be Aware of State Laws: Familiarize yourself with local regulations regarding lane splitting and lane sharing, as they vary across states.
- Practice Defensive Driving: Always be vigilant and maintain a safe distance from motorcycles, recognizing their vulnerability on the road.
