Roadcheck Results Mixed
Is There A Trend?
The 2014 Roadcheck results have been released and overall driver Out–of–Service rose slightly while truck Out–of–Service dropped nearly 2 percentage points. These statistics are the result of over 73,000 inspections conducted during this year’s three day event across North America.
CVSA publishes data each year regarding the distribution of violations compared across several years. The top three violations for vehicles, drivers, and hazardous materials are shown below. A few are trending down but, for the most part, over the past three years a particular violation will drop and then increase the next year.
It’s no surprise that the top three vehicle violations are related to lights, brakes and tires but knowing that doesn’t get us any closer to divining what condition the “average†truck rolling down the highway is in.
The problem lies with the inspection selection process which is skewed toward motor carriers with a higher level of previous problems. The Roadcheck statistics, while interesting, don’t necessarily represent a true cross section of the motor carrier industry. It is indeed good news that vehicle Out–of–Service dropped but next year’s number could just as easily show an increase.
