Professor David J. Hanson is an alcohol researcher and has been involved in this area of research for more than 40 years, according to the website Alcohol Problems & Solutions, and among his findings is his opinion that breathalyzers are not 100 percent accurate; in fact, they should really be called blood alcohol content “estimators.”
Many lawyers know about the dispute regarding breathalyzers – not everyone believes that breathalyzers provide foolproof measurement of BAC.
But truck drivers, for instance, are held to a higher standard, because professional truckers shouldn’t risk injury or death to other motorists by causing a DUI truck accident because they’ve been drinking.
It doesn’t take much for a trucker to go over the limit. In Texas, truckers are deemed to be driving under the influence if their BAC is .04 or higher, which is a much stricter standard than the general motorist’s .08 limit.
When it comes to breathalyzers, there are age and gender and other factors that can cause variances from one result to another; but, again, the .04 limit is a stricter standard. Any trucker who drinks, gets behind the wheel, and causes a truck accident should be held accountable for that accident, along with other responsible parties.
