Driving while impaired by alcohol is often associated with binge drinking - drinking five or more drinks in a single session. In a U.S. study that tracked the prevalence of drinking and driving over a ten year period (1993-2002 with over 100,000 annual phone interviews) 80... 

Previous studies showed that motorcyclists drink and drive as often as car drivers but with lower BAC. Moreover, when they know that they may drink heavily, motorcyclists typically leave their motorcycle and use their car. They may be trying to compensate for the greater vulnerability of their habitual transport mode by more cautious behavior. In total, 12,507 car drivers and 4,483 powered two-wheeler drivers from 19 countries were asked about their attitudes and behaviors related to driving while impaired. The results showed large differences between countries in alcohol consumption and reported drink driving. More specifically, the drivers from Northern Europe reported far less drink driving than Southern drivers. In most countries motorcyclists drink and drive almost as often as car drivers do. The comparison of motorcyclists and car drivers showed similar patterns of drink-driving processes.

However, equating temporary with benign (harmless) would be misleading because some of marijuana s so-called temporary effects can last a lifetime. For example, studies have shown that driving while high can increase the possibility of a motor vehicle accident. In this case, the consequences of marijuana s short-term effects (impaired attention, motor skills, and reaction times) might quickly transform temporary to permanent. ... 

Alcohol may increase the risk of gastrointestinal haemorrhage associated with NSAIDs. The skills related to driving are impaired by indometacin and phenylbutazone and this is made worse if patients drink alcohol while taking phenylbutazone, but this does not appear to occur with indometacin. A few isolated reports attribute acute renal failure to the concurrent use of NSAIDs and acute excessive alcohol consumption.

A large body of evidence demonstrates that interacting with in-vehicle devices while driving can impair driving performance on a number of safety critical measmes. But does this degradation in driving performance translate into an increase in crashes and crash risk A number of studies have been conducted to examine this question. 

As we move away from the sterile laboratory environment to a more complex one such as a driving simulator, or an experimental study on the road, or a naturalistic road study we can expect perception reaction times and brake reaction times to increase. And they do. In a review of 31 studies of brake reaction time. Green (2000) noted that mean times varied from a short 0.42 seconds (when drivers in a simulator responded to an expected light while impaired by carbon monoxide Wright and Shephard, 1978) to a high of 1.95 seconds (for older drivers responding to an unexpected stop by a policeman Summala and Koivisto, 1990).

One of Linda s primary reactions to chemicals is joint and muscle pain so severe that even walking is difficult for her. Another common reaction for her is cognitive impairment. She carries oxygen in her car in case she has a chemical reaction while driving. A significant loss she has experienced due to MCS is access to her church. 

Hazardous tasks May impair mental or physical abilities patients should observe caution while driving or performing other tasks requiring alertness. 

Ocular formulations of pilocarpine have caused visual blurring that may result in decreased visual acuity, especially at night and in patients with central lens changes, and impairment of depth perception. Advise caution while driving at night or performing hazardous activities in reduced lighting. 

Amyl nitrite and other poppers can cause confusion, dizziness, drowsiness, and a slowed perception of time, even with only limited use. For these reasons driving, operating machinery, or any other work that requires being alert or responsive, is not recommended while under the influence of amyl nitrite. Amyl nitrite can also cause people to feel less inhibited, relaxed, and give them a sense of well-being and intensified emotions. This can impair judgment, especially when it comes to sexual behavior. 

Driving and hazardous work should not be performed while taking benzodiazepines because they can impair mental alertness and coordination. Persons taking any of the benzodiazepine medications should never drink alcohol. Use during pregnancy and nursing should be avoided as well.
