One issue that can often impair a driver’s ability to pass their CDL physical examination is blood pressure. In order to pass the physical without exception, the driver’s blood pressure must be measured at or equal to 140/90. With that in mind, it is important that drivers refrain from taking anything which can increase their blood pressure prior to the examination. Caffeine in any form, whether coffee or soda or energy drinks, will raise your blood pressure. Thus, steer clear of it the day of your physical. Nicotine will likewise raise your blood pressure, so you should avoid smoking or using tobacco in any form on the day of one’s physical. You should also avoid any products that contain nicotine, such as nicotine gum or nicotine patches. And if you’re on blood pressure medication, make sure you’re taking it as prescribed before presenting for your physical exam.
