You’ll likely be tested at the start of employment, after any vehicle accident resulting in loss of life, or totaling a vehicle or bodily injury where you (the driver) is cited. You may also be tested randomly to maintain a 10% annual percentage rate of random testing. The final reason you (not you specifically because we trust you) might be tested is because of reasonable suspicion. If an employer is able to provide specific reasoning including appearance, behavior, speech or body odor, they may test an individual.
