VERY MANY more times than a sober driver. Being intoxicated greatly weakens your ability to focus on driving.
You are probably referring to .08% alcohol in the blood stream, since at 8% you would have been dead long before. In any case, in Canada at least, .08% blood alcohol is the amount considered to cause serious impairment in the operation of a motor vehicle. This amount or above will usually result in a "driving under the influence" (DUI) charge. Many other countries have even lower limits, with a few allowing no alcohol at all while driving (this is true in some parts of Canada for beginning drivers). The figure itself means that 8/10,000'ths of your blood consists of ethyl alcohol. At .20% most people will become unconscious; at .40% death from alcohol poisoning occurs.
The latter question does not state that the total is out of 100, so in effect it could be 50 accidents out of a million were the result of alcohol. Also, the first question states that the person who caused the accident was a drunk driver, however the second does not make this point. As such an incident could be said to involve alcohol because a drunk person walked across the road and caused someone to swerve etc.
Below are the stats as quoted from NHTSA. 25% had .08 BAC or higher in 2008. "In 2008, 31 percent of the young drivers (15 to 20 years old) who were killed in crashes had a blood alcohol concentration (BAC) of .01 grams per deciliter (g/dL) or higher; 25 percent had a BAC of .08 or higher."
If everyone drive exactly as is recommended and follow all of the rules of the roads, accidents would decrease to a very low level but there would never be a time that there would be no accidents. But I am going to say that more than 50% of car crashes could be prevented just by drivers following the laws and rules.
Decrease
drinking alcohol does slow down your reaction but it does not avoid accidents it only causes them.

Alcohol has a serious impact on the ability to drive safely. Some of the effects of alcohol are impaired reaction times, poor judgement, impaired vision, reduced concentration, and sleepiness.
Speed, drivers attention level, drivers ability, drivers ability to discern danger.
Your response time to a situation is determined by your ability to recognize a situation and in reflexes, in short a cognitive response followed by a motoric response. Decreased visibility and lessened ability to retain concentration probably account for the increased response time of impaired drivers.
It depends on how aggressive the alcohol-impaired drivers are.
