To help you stay alert and safe while driving, you should _______.

Unfortunately, several prescription and over-the-counter drugs can produce drowsiness, sleepiness, or impaired coordination, making them hazardous for CMV drivers. If you have any questions regarding a medication's side effects, check the warning label or ask your pharmacist or doctor. Never use coffee, fresh air, or, especially, alcohol to combat tiredness. Sleeping till you are rested is the only "cure" for being tired.
