How many meters does it typically take to stop a vehicle traveling at 80Km/h?

When evaluating the stopping distance of a vehicle traveling at 80 km/h, it's important to consider several factors, including perception time, reaction time, and braking distance.

For a vehicle moving at this speed, the average stopping distance is typically around 140 meters. This figure is derived from the combination of how long it takes a driver to perceive a hazard, react, and then physically stop the vehicle.

At 80 km/h, the vehicle travels approximately 22 meters per second. When factoring in an average perception and reaction time of about 1.5 seconds, the vehicle can travel about 33 meters before the brakes are applied. The braking distance then depends on factors such as the vehicle's braking capacity and road conditions.

Once the brakes are applied, deceleration plays a crucial role in determining how much farther the vehicle will travel before coming to a complete stop. Under normal conditions, the combined distance from perception to complete stop can indeed total around 140 meters, making this the correct choice for the stopping distance at this speed.
