Drafting Behind Vehicles – Definition & Detailed Explanation – Bicycle Riding Techniques Glossary

I. What is Drafting Behind Vehicles?

Drafting behind vehicles, also known as slipstreaming, is a technique commonly used by cyclists, runners, and even drivers to reduce air resistance and improve efficiency. When drafting behind a vehicle, the person or vehicle behind is able to take advantage of the reduced air pressure created by the lead vehicle, allowing them to travel at a faster speed with less effort.

II. How to Safely Draft Behind Vehicles

1. Maintain a safe distance: It is important to maintain a safe distance behind the vehicle you are drafting behind to avoid any potential accidents. Experts recommend staying at least one to two car lengths behind the vehicle.

2. Stay visible: Make sure you are visible to the driver of the lead vehicle by using lights, reflective gear, and hand signals if necessary.

3. Communicate with the driver: If possible, communicate with the driver of the lead vehicle to ensure they are aware of your presence and intentions.

4. Be prepared to brake: Always be prepared to brake in case the lead vehicle suddenly slows down or stops.

III. Benefits of Drafting Behind Vehicles

1. Increased speed: Drafting behind a vehicle can help you increase your speed without expending as much energy.

2. Reduced air resistance: By riding in the slipstream of a vehicle, you can reduce the amount of air resistance you face, making it easier to maintain a higher speed.

3. Energy efficiency: Drafting behind vehicles can help you conserve energy, allowing you to ride or run longer distances with less effort.

IV. Potential Risks of Drafting Behind Vehicles

1. Reduced visibility: Drafting behind a vehicle can reduce your visibility to other drivers, increasing the risk of accidents.

2. Sudden stops: If the lead vehicle suddenly stops or slows down, it can be difficult to react quickly enough when drafting behind them.

3. Exhaust fumes: Drafting behind vehicles can expose you to harmful exhaust fumes, especially if you are in close proximity to the vehicle for an extended period of time.

V. Tips for Drafting Behind Vehicles

1. Choose the right vehicle: Select a vehicle that is traveling at a consistent speed and is large enough to create a noticeable slipstream.

2. Practice in a safe environment: Before attempting to draft behind vehicles in traffic, practice in a controlled environment to get a feel for how it works.

3. Be aware of your surroundings: Always be aware of your surroundings and be prepared to react to any changes in traffic or road conditions.

VI. Legal Considerations for Drafting Behind Vehicles

1. Check local laws: Before drafting behind vehicles, make sure to familiarize yourself with the local laws and regulations regarding this practice.

2. Use caution: While drafting behind vehicles can be beneficial, it is important to use caution and prioritize safety at all times.

3. Respect other road users: Be considerate of other road users and avoid drafting behind vehicles in a way that may disrupt traffic flow or endanger others.
