in ideal weather and road conditions.
Explanation:
Minimum Safe Following Distances
Leave plenty of space between you and the vehicle ahead, including bicycles. If it stops quickly, you will need time to see the danger and stop.
Using the Two-Second Rule
At any speed, you can use the two-second rule to see if you are far enough behind the car in front of you:
- Watch the vehicle ahead pass some fixed point - an overpass, sign, fence corner, or other marker.
- Count off the seconds it takes you to reach the same spot in the road ("one thousand and one, one thousand and two...").
- If you reach the mark before you finish counting, you are following too closely. Slow down and check your following distance again.
The two-second rule applies to any speed in ideal weather and road conditions. If road or weather conditions are not good, double your following distance. You should also double your following distance when driving a motor home or towing a trailer.
Following Distance For Trucks
A truck or any vehicle towing another vehicle may not follow within 300 feet of another truck or vehicle towing a vehicle. This law does not apply to overtaking and passing, and it does not apply within cities or towns.

Does BeH2 violate the octet rule?
The octet rule only applies to elements that are heavy enough to have reached the second shell of electrons. In the first shell, the octet rule does not apply because the first shell is completed with only two electrons, not eight. So no, the octet rule does not apply to beryllium hydride.
How does newtons second law apply of changing the direction of an object?
Newton's Second law involves acceleration which is changing the velocity. Velocity can be changed in two ways, direction or speed, so Newton's Law applies to both.
Is it that reaction distance increases with speed while the reaction time stays the same?
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
What is the increased probability on a per-mile basis of getting involved in a car accident by observing only a one second vs two second rule for following?
Only a fool breaks the two second rule.
When to use the two second rule when driving?
When following a vehicle in front of you.
To what does the term two-second rule refer?
The second term refers to the second opportunity that someone has to govern a given country.
When does the Pythagoran theorem apply?
Any time there is a right triangle. The rule of a2+b2=c2 applies to the two legs squared = the hypotenuse.
What is the two-second rule was designed for good weather and clear visibility?
true
What equation represents the velocity of a light?
The speed of light in a vacuum is 300,000 kilometers per second - you don't need an equation for that. Two equations that involve the speed of light are: 1) Speed = wavelength x frequency (this equation applies to any wave, not just light) 2) Snell's law, which relates the speed of light in different substances with the substance's index of refraction. The equation for the speed of light is: c = (299,792,458 meters per second) divided by (refractive index of the medium) The refractive index of vacuum is precisely 1 .
What may be considered a good stationary object when applying the two second rule?
An animal
What may not be considered a good stationary object when applying the two second rule?
An animal
How does these two quantities determine the speed of light?
The distance in meters covered by light in one second is considered to determine the speed of light. Speed of light is 3*108m/s. The unit of speed of light is meters per second.
