DOT is short for Department Of Transportation. The Omnibus Transportation Employee Testing Act of 1991 is a United States federal law that requires alcohol and drug testing for employees in the trucking, mass transit, pipe lines and railroads. The vast majority of employees who work in the transportation industry are covered by this act. Methamphetamine, codeine, morphine, marijuana, opiates and cocaine are some of the drugs prospective transportation employees are often tested for.
A drug test can be administered by taking a sample of urine, oral fluid or hair. The tests can be administered in just a few minutes, and the results are usually available in just three days. In many cases, people can get the results of a drug test instantly. If a person undergoes instant drug testing, then the results are available in just a few seconds.
Today’s drug tests are very accurate. Many people try to cheat a drug test by using home remedies to quickly get the drug out of their system. However, these methods are typically ineffective.
The reason the Department of Transportation employees are required to undergo drug testing is to keep themselves and the people they transport safe. People who drive a vehicle or operate machinery while using drugs or alcohol are much more likely to injure themselves and others. Furthermore, drug testing helps prevent employers from losing money.
Department Of Transportation employees are not only required to undergo drug testing before they get hired, but they may also be subjected to random drug-testing. Employers are responsible for keeping the environment drug-free, and random drug testing helps them do that.
