Drink plenty of water so that you can provide the required urine sample. This sample is not used for a dot drug test (hair or urine), but rather to check for the presence of sugars, protein, or blood – all of which can indicate certain health conditions.
Get plenty of sleep the night before your DOT physical exam and give yourself plenty of time to get to your appointment. Rushing to gather paperwork at the last minute – or dealing with traffic delays – can increase your stress levels before your test.
