Question

no matter how fast you are traveling, you only need 2 seconds to be able to stop before you enter an intersection. group of answer choices true false

Answer 1

The statement is false because stopping distance varies based on speed, road conditions, reaction time, and braking efficiency. The two-second rule is for following distance and assumes moderate speed and good road conditions.

Step-by-step explanation:

The statement that no matter how fast you are traveling, you only need 2 seconds to be able to stop before you enter an intersection is false. The stopping distance for a vehicle depends on several factors, including the speed of the vehicle, road conditions, driver reaction time, and the efficiency of the brakes. For example, a car traveling at a higher speed will require a longer distance to stop compared to a car traveling at a lower speed. Wet or slippery roads can also significantly increase the necessary stopping distance. Reaction time is another crucial element; this is the time it takes for a driver to perceive a hazard and begin braking. Typical driver reaction times can be several tenths of a second, which, when combined with the actual braking distance, can add substantially to the overall stopping distance. Safety recommendations such as the two-second rule are for following distance, not stopping distance, and are generally based on driving at a moderate speed with good road conditions.

Answer 2

The statement is false. The stopping distance of a vehicle depends on various factors including speed, road conditions, and reaction time.

Step-by-step explanation:

The statement that no matter how fast you are traveling, you only need 2 seconds to be able to stop before you enter an intersection is false. The distance required to stop a vehicle depends on various factors including the speed of the vehicle, the road conditions, and the driver's reaction time. The stopping distance increases with higher speeds and poorer road conditions.

For example, let's consider the braking distances for a car initially traveling at 30.0 m/s. According to Figure 2.34, on dry pavement, it would take approximately 45 meters to stop the car assuming a 0.500 s reaction time. On wet pavement, the stopping distance increases to about 63 meters.

Therefore, it is important to follow speed limits and maintain a safe distance from the vehicle ahead to ensure you have enough time and distance to stop safely before entering an intersection.
