What most affects how far ahead you must look, vehicle control, and the distance you need to stop?.
lutik1710 [3]

The speed is impacted by how far a person has to go while driving, the control of the vehicle, and where a person has to stop the vehicle.

<h3>What is a vehicle?</h3>

A vehicle is a medium of transport used by a person for traveling in and around the country.

While driving a vehicle, the speed is the most important factor that tells about how far a person has to go, how to control the vehicle, and at which point he/she has to stop it. This can be controlled by a speedometer which is present in almost each and every vehicle to monitor the speed.

Therefore, the stopping and controlling of a vehicle totally depend on the speed of the vehicle.
