Driving license notes

Alcohol

  • 70 people per year are killed in alcohol-related traffic accidents. That is 20% of the total number of killed.
  • 15,000–20,000 drunk drivers per day.
  • 30,000 people are caught drunk driving each year. 10,000 of these are due to drugs.
  • 50% of all drivers killed in fatal single-vehicle accidents were under the influence of alcohol.
  • 30% of cyclists and pedestrians killed were under the influence of alcohol.
  • 90% of the drunk drivers are men, primarily younger and middle-aged.
  • Young drivers are overrepresented in these statistics. They drive drunk more often and run a greater risk of being killed.

Example

How much spirits (40%) corresponds to 50 cl of light beer with 3.5 percentage alcohol by volume?

Answer: 3.5 * 50 * 0.025 = 4.38 ≈ 4 cl

Children safety

  1.  Height > 350 cm = can use normal seat belt
  2. Height < 350 cm = have to use safety devices such as baby car sit
  3. short distance && ( age > 3 year) && (Height < 350 cm) = can use normal sit belt
  4. short distance && ( age < 3 year) && (Height < 350 cm) = can use behind baby sit provided by taxi

Pollutions

Hydrocarbons (HC)

  • Causes cancer.
  • May impact on genetic material.
  • Contributes to the formation of tropospheric ozone.

Nitric oxide (NOx)

  • Contributes to the acidification of soil and eutrophication of lakes.
  • Impacts on human genetic material and airways.
  • Contributes to the formation of tropospheric ozone.

Tropospheric ozone

  • Ozone that forms too close to the ground is harmful to plants and animals.

Calculate kmh to mh = remove 0 then multiply by 3. For example 70kmh. So per 1 second it goes (7*3) = about 21 / 20 m.

Wild animal
