Dot Physical Exam

 Truck drivers deliver everything from the food we eat to the medications we need to the material necessary for construction – and everything in between, including passengers. The legal ability to drive certain types of vehicles requires that you have a commercial driver’s license (CDL), which means that you need to have a Department of Transportation (DOT) physical to obtain and maintain that licensure.

Let’s talk about some of the most frequently asked questions (FAQs) we receive about DOT physicals:

Does Everyone Who Drives a Truck Need a DOT Physical?

You need a DOT physical to obtain your CDL license. You’ll need a CDL if the gross vehicle weight rating of the vehicle is 26,0001 pounds or more, or if you’re towing a vehicle that weighs more than 10,000 pounds. You’ll also need to have a CDL if you drive a vehicle that can carry more than 24 passengers at once.

You’ll need to have a CDL to drive a vehicle that can tow two or three trailers at once, one that carries hazardous waste, or one that carries liquid or liquified gases. For safety purposes, your employer may ask you to obtain a DOT physical even if the vehicle you drive doesn’t meet the requirements for a CDL license.

What Does a Practitioner Look for During a DOT Physical? 

During the physical, your practitioner will evaluate your blood pressure and heart rate. You’ll also be asked questions about your medical history, such as if you have narcolepsy (a sleeping disorder), have had seizures, or have had a heart attack or stroke. You may be referred to a cardiologist to ensure that any heart issues are well-managed enough for you to qualify for a CDL.

The doctor will also check your lung function and inquire whether you use oxygen therapy. If you have lung issues, you may need to visit your pulmonologist to receive clearance that it’s safe for you to drive these large vehicles.

You’ll receive a neurological/brain infection test, and the doctor will check your reflexes. Hearing and vision are also screened during your DOT physical exam.

Can You Pass a DOT Physical if You Have Diabetes?

If you have type II diabetes that’s controlled with oral medication alone, you’ll be able to pass your DOT physical. However, if you have type I diabetes or use insulin to control your type II diabetes, you, unfortunately, will not be able to receive your required certificate of health. You could also experience an issue if your blood sugar isn’t well-controlled.

How Often Do You Need a DOT Physical?

Every two years you’ll need to have a DOT physical in order to maintain your licensure. If you have certain health conditions like hypertension (high blood pressure), you may need to have a physical done annually.

What Are the Visual Acuity Requirements in Texas?

You’ll need to have a visual acuity of at least 20/40 vision in both eyes with corrective eyewear. Your practitioner will also assess your color vision.

Do You Need to Pass a Drug Test to Pass Your DOT Physical?  

You won’t have to pass a drug test to obtain your DOT physical unless your employer requires it. You’ll submit a urine sample that tests your protein and sugar levels.

Do You Need to Pass a DOT Physical if You Relocated to Texas?

The medical certificate you received in another state is still valid when you move to Texas. However, your employer may want you to pass a DOT physical from their chosen medical examiner.
