To improve the **safety** and **efficiency** of a vehicle, it is advisable to use **mudflaps or rubber strips** alongside the wheels. These elements complement the effect of the **mudguard**, which is a part of the vehicle designed to protect against mud, water, and other elements that the wheels may lift when turning.

- The **mudflaps or rubber strips** help minimize the amount of dirt and water that the wheels can project towards the vehicle and other road users. This not only keeps the vehicle cleaner but also improves **visibility** and reduces the risk of accidents caused by splashes.

- Additionally, by reducing air resistance and the amount of dirt that adheres to the vehicle, it contributes to a **more efficient drive**, as the vehicle does not need to expend as much energy to move forward. This translates into lower fuel consumption.

Therefore, the use of mudflaps or rubber strips is a practical and effective measure to improve both the safety and efficiency of the vehicle.
