Drive for Conditions

Early morning jackknife.

Change . . . or Die

As we transition from fall to winter weather, our driving habits have to transition as well. The main habit to develop is to drive for conditions. Usually, this means slowing down.

Three tractor-trailers recently crashed on I-75. The primary root cause of this safety event was loss of vehicle control and a jackknife into the medium, tearing out a section of the wall.  Debris caused a third tractor-trailer to crash and for both directions of 1-75 to be shut down for four hours, affecting thousands of people.

Slow down for slick roads. Slow down for wet roads. As the Missouri CDL Manual advises:

Reduce speed by about one-third (e.g., slow from 55 to about 35 mph) on a wet road. On packed snow, reduce speed by a half, or more. If the surface is icy, reduce speed to a crawl and stop driving as soon as you can safely do so.


Other News

With the new budget bill, Congress suspended the 1AM to 5 AM provision and the 168-hour rule the DOT imposed on the 34-hour restart provision. The rule is suspended for a period of one year for the DOT to further study the issue.  The 30 minute rest break requirement is still in effect.

Merry Christmas! Have a safe holiday season.



Medical Cards for Drivers

Part 391

Donald Jerrell of HNi recently posted a blog about driver DOT medical cards (certification).

Deadlines for Medical Cards for Drivers

Some important dates for medical certification to keep in mind include:

  • Jan. 30, 2014: This is the effective date (now passed) that commercial drivers must submit their medical certificate to their state Department of Motor Vehicles.
  • Jan. 30, 2015: Interstate commercial drivers must keep copies of their medical examiner’s certifications with them in their vehicle until this date.
  • May 21, 2014: As of this date, all drivers must get medical certification from a health care pro listed in the National Registry of Certified Medical Examiners.

Finding a Certified Doctor

Drivers only can get medical certification from a certified medical examiner who’s on the National Registry. The state DMV syncs its records of who’s a certified medical pro with the registry.


A company must verify that a doctor is certified, according to 391.51 (requirements for driver qualification file):

(9) A note relating to verification of medical examiner listing on the National Registry of Certified Medical Examiners required by §391.23(m).
