Who is responsible to notify a CDL driver that his DOT physical is due to expire?
Responsibility = response + ability, or the ability to respond.
Due to the stringent DOT medical examination requirements, I recommend every driver renew his medical certificate at least 30 days before it is due to expire. Both the driver and his or her organization should have a reminder system in place so this gets done.
About one out of three men have sleep apnea, many times due to a buildup of fatty tissue in the neck. Testing or retesting may be required.
Rushing to do your medical exam (or drinking coffee, taking cold medication, etc.) can raise your blood pressure, resulting in a 90 day card, and another visit to the examiner.
For best results, plan well ahead of the due date, relax, do the exam and get your medical certificate. And don’t forget to take it to your DMV or Secretary of State, etc., so your federal records can be updated.
