When BAC is 05 how many times greater are your chances of an accident?
The risk of being involved in a crash increases significantly at 0.05 BAC and above. The relative risk of being killed in a single-vehicle crash with BACs of 0.05–0.079 is 7–21 times higher than for drivers at 0.00 BAC.
If your PAS shows a BAC of 0.05%, the officer may require you to submit to either a breath or blood test. If a subsequent test reveals a BAC of 0.05% or higher, the officer will issue you an order of suspension and arrest you for DUI (CVC §23140).
If a motorist has reached a BAC of slightly above . 05 percent after drinking, the risk for causing a motor vehicle accident doubles. The risk is six times as great when driving with a BAC of . 10 percent.
0.4–0.5% (400–500 mg/dL) Potentially fatal and a person may be comatose. Above 0.5% (500 mg/dL) Highly dangerous/fatal blood alcohol level. Impairment of motor skills may occur at blood alcohol levels lower than 0.08%.
At a BAC of 0.05 -- completely street-legal -- your odds of wrecking your car have increased 100 percent versus someone who hasn't drunk at all. At 0.08, your crash odds have roughly tripled. Depending on your weight and gender, it doesn't take many drinks to reach those BAC thresholds.
If your BAC reaches 0.08, you are three times more likely to have a traffic collision than if your BAC were zero. If your BAC reaches 0.25 percent, your chances of having a traffic collision are 25 times greater.
The general rule of thumb is that 2 standard drinks in the first hour will raise your BAC to 0.05%, and 1 standard per hour thereafter will maintain that level.
After a heavy night of drinking, it can take more than 18 hours for your blood alcohol concentration to get back to zero.
The National Transportation Safety Board is recommending states lower that limit to . 05 percent. Research shows that some people are impaired at . 05 percent; science also tells us that how drunk you get when you drink depends on a variety of factors.
0.5mg is equivalent to one small beer, so nowhere in Europe is there much tolerance for drinking. Be very aware that there are variances within this framework.
What is your BAC after 1 beer?
Behonick said if a 150 pound man has one standard drink, it would give him a BAC of about 0.025 percent. A standard drink is defined as 12 ounces of beer, 4 ounces of wine or one shot of 80 proof alcohol.
Shouldn't a BAC of 0.42 — five times the legal limit — kill you?

As a driver's blood alcohol concentration (BAC) rises, so does the risk of being involved in a crash. 0.05 = double the risk. 0.08 = 7 times the risk. 0.15 = 25 times the risk.
The legal limit is 35milligrams. Therefore four times the legal limit would be 140 milligrams. It is rare to come across readings of over 150 milligrams so your husband's reading is at the top end of what the court's are accustomed to dealing with.
Utah is the first and only state to adopt the . 05% BAC limit, based on recommendations from the National Transportation Safety Board.
BAC Between 0.06% and 0.10%
Your reflexes, reasoning, and vision will start to be impaired. You may be charged with a DUI at a 0.08% BAC and above if you get found driving.
