Sober driving precision predicts impairment from alcohol in a simulated driving task,” Accident Analysis and Prevention, vol. The main differences between normal driving and drinking driving were analyzed with ANOVA method firstly. The results showed that SP_AVG was significantly higher in drinking driving state than in normal state . The key stakeholders for reducing drink–driving accidents are the police; they are responsible for enforcing drink–driving laws and for generally stepping up drink–driving countermeasures.

In states that have not yet established a THC blood level that triggers a presumption of impaired driving, a driver may similarly be convicted of impaired driving based upon the officer’s observations and performance on other sobriety tests. For drivers suspected of drug-impaired driving, drug testing screens are typically performed in scientific laboratories so that the results will be admissible in evidence at trial. Due to the overwhelming number of impairing substances that are not alcohol, drugs are classified into different categories for detection purposes. Drug impaired drivers still show impairment during the battery of standardized field sobriety tests, but there are additional tests to help detect drug impaired driving. It is a crime for a driver to have a bodily alcohol content of .08 or greater if over age 21 or .02 or greater if under 21.


Although 14 percent of drivers in alcohol–related fatal crashes in 2002 were between 16 and 20, this age group represents only 7 percent of the population. Likewise, 49 percent of drivers in alcohol–related fatal crashes were ages 21 to 45, and this age group makes up 35 percent of the population. The FARS data also provide information on the characteristics of drivers involved in alcohol–related fatal crashes—their age, gender, previous convictions and license suspensions, BAC, and safety belt use. Males are more likely than females to be involved in alcohol–related fatal crashes.

With alcohol consumption, a drunk driver’s level of intoxication is typically determined by a measurement of blood alcohol content or BAC; but this can also be expressed as a breath test measurement, often referred to as a BrAC. A BAC or BrAC measurement in excess of the specific threshold level, such as 0.08%, defines the criminal offense with no need to prove impairment. In some jurisdictions, there is an aggravated category of the offense at a higher BAC level, such as 0.12%, 0.15%, or consequences of drinking and driving 0.25%. In many jurisdictions, police officers can conduct field tests of suspects to look for signs of intoxication. The US state of Colorado has a maximum blood content of THC for drivers who have consumed cannabis, but it has been difficult to enforce. It has been known that alcohol use impairs driving skills and increases accident risk. It has been found that while driving under the influence of alcohol, the risk of having an accident causing injury or death increases exponentially .

However, 100 milliliters of blood weighs essentially the same as 100 milliliters of water, which weighs precisely 100 grams. Thus, for all practical purposes, this is the same as the simple dimensionless BAC measured as a percent. The per mille measurement, which is equal to ten times the percentage value, is used in Denmark, Germany, Finland, Norway, and Sweden. Convicted drunk drivers are subject to a $1,000 penalty for two consecutive years under the Driver Responsibility Act, for a total of $2,000 in additional costs.

  • Fillmore et al. expressed that alcohol significantly impaired driving performance, which included deviation of lane position, line crossings, steering rate, and driving speed.
  • Therefore, the trend internationally is to lower the maximum rates allowed.
  • It was indicated that SP_SD at the BAC levels of 0.06% and 0.09% was significantly higher than at the level of 0.00% ().
  • Legal trouble can also ensue, which can result in the person being fined, losing their license, or even being arrested.
  • In contrast, 15 percent of zero–BAC drivers in fatal crashes were speeding .
