Heat and your Truck


During the last bulletin I discussed the precautions that your drivers must take from the heat of the summer. In order for drivers to operate a commercial motor vehicle (CMV) in a safe manner they also need to understand how heat affects the operation of the CMV. Two areas that drivers must pay attention during their inspections are the engine coolant and the tires.


Engine Coolant


Approximately 5 years ago the OEM truck manufactures introduced extended life coolant (ELC) into the industry. With each EPA change the operating temperature of the engine has increased 10 to 15 degrees. It is estimated that 50% of all engine failures are associated with an overheat condition of the engine.


With today's emission systems an engine running low on coolant runs the risk of damage the emission components such as the exhaust gas recirculation or EGR.


The benefit of using ELC is the fact that you can improve the engine's heat transfer rate by 12 to 13 percent over conventional anti-freeze.


During the pre-post trip inspection driver should:


1. Make sure that the coolant level is within range of the marking on the side of the coolant reservoir.


2. If the coolant level is low contact your Idealease service provider immediately for direction. ELC coolant should be a red/orange color and should be free of dirt, debris, rust and other contaminants.


Do NOT mix ELC with conventional anti-freeze!


3. If when operating a CMV a dash light comes on with an overheat warning immediately pull the unit into a safe parking place and contact your Idealease service provider for direction. Operating the unit in an overheat situation can severely damage the engine.




During the summer season, when the ambient temperatures can get well over 100°F, and some road temperatures can reach almost

200°F, the heat problems caused by under inflation are more extreme. Tires that are run under inflated will be more prone to failure in these temperatures. A very famous tire engineer once stated, "Heat is to tires as Kryponite is to Superman"... in other words, it's worst enemy. Taken all together, hot summer temperatures, under inflated tires, heavy loads, and traveling at high speeds (not that this ever happens), and you have a recipe for tire disaster.... that's exactly why you see more alligators on the highway in the summer season.


What can drivers do to minimize tire related issues during the summertime months?


1. Tire pressures need to be checked more frequently in the summer.


2. Tire pressures need to be checked when the tire is "cold" and not after operation. Pressures can increase during operation when "hot" by as much a 15% giving you a false reading.


3. Inspect tires for punctures and damage during pre-post trip inspections and stops. Tire punctures tend to increase during the summer because the tread rubber becomes hotter and "softer" and acts as a magnet to nails and road debris.


4. Immediately report to your Idealease service provider tire conditions that need attention.






The Federal Motor Carrier Safety Administration has announced that some 30,000 medical examiners are now certified and listed on the National Registry of Certified Medical Examiners. The agency noted that an additional 22,500 examiners have initiated the process for obtaining certification.


Effective May 21, 2014, all new USDOT medical examinations for interstate truck and bus drivers (both CDL and non-CDL drivers) are required to be performed by a medical examiner who has completed the required training and passed a certification test.





The FMCSA's Office of Analysis, Research, and Technology has recently announced that the following reports have been published:


Evaluating the Potential Safety Benefits of Electronic Hours-of-Service Recorders-Final Report: 


This study evaluated whether Class 7 and Class 8 trucks equipped with electronic hours-of-service recorders (EHSRs) have lower (or higher) risks of crashes and hours-of-service violations than those without EHSRs. The results show a clear safety benefit, in terms of crash and HOS violation reductions, for trucks equipped with EHSRs.


Of particular significance are the following findings:


*  EHSR-equipped trucks had a significant 12% lower total crash rate than non-EHSR-equipped trucks for all crash types and a significant 5% lower crash risk than non-EHSR-equipped trucks for preventable crashes.


*  EHSR-equipped trucks had a significant 53% lower driving-related HOS risk than non-equipped trucks and a significant 49% lower non-driving-related HOS violation risk than non-equipped trucks.


Wireless Roadside Inspection Phase II-Final Report:


The Wireless Roadside Inspection Program is demonstrating the feasibility and value of electronically assessing truck and motor-coach driver and vehicle safety. Pilot Tests were conducted in order to prototype, test, and demonstrate the feasibility and benefits of electronically collecting safety data messages from in-service commercial vehicles and performing wireless roadside inspections using three different communication systems. The results demonstrate the capability to increase commercial vehicle inspections and potentially to realize improvement in commercial vehicle safety without increasing the burdens on enforcement or on compliant operators.


Study of the Impact of a Telematics System on Safe and Fuel-efficient Driving in Trucks:


This report evaluates telematics systems focusing on safe and fuel-efficient driving. Telematics is a technology that combines telecommunications (i.e., the transmission of data from on-board vehicle sensors) and global positioning system (GPS) information (i.e., time and location) to monitor driver and vehicle performance.


In this study, telematics was used to monitor various driver performance parameters, including unsafe events, speeding, engine revolutions per minute, and fuel economy. During the intervention phase of the study (during which drivers were provided with information, feedback, training, and/or incentives to modify their driving behaviors), drivers of sleeper cabs showed a 55% reduction in less severe unsafe events and a 60% reduction in more severe unsafe events.


Also during this phase of the study, fuel economy improved by 5.4% for drivers of sleeper cabs and by 9.3% for drivers of day cabs.

The data suggest that fuel economy correlates to safe driving. Because safe driving can be said to conserve fuel, and conserving fuel reduces emissions, safe driving can also be said to reduce emissions.


Smart Infrared Inspection System Field Operational Test: Final Report:


The Smart Infrared Inspection System (SIRIS) is designed to assist inspectors in determining, by measuring thermal data from the wheel components, which CMVs passing through the system are in need of further inspection. As a vehicle enters the system, infrared cameras installed on the road measure temperatures of the brakes, tires, and wheel bearings on both wheel ends of CMVs in motion. The thermal data are then presented to enforcement personnel in the inspection station. Enforcement staff are automatically alerted to vehicles that are suspected to have a violation.


The test was evaluated the performance of the prototype system and to determine the viability of using such a system for CMV enforcement. Overall, the enforcement personnel who have used SIRIS for screening purposes have indicated that SIRIS has the potential to be an effective tool. With improvements in detection algorithms and stability, the system will increase overall enforcement productivity by accurately identifying a higher percentage of potentially dangerous CMVs for inspection.

National Truck Driver Appreciation Week

 Sept. 14-20, 2014


Make plans now to recognize your drivers.


CVSA Brake Safety Week

Sept. 7-13, 2014







Question of the Week:


Is there any update on the CSA program when it comes to tires?




Not at this time. Penalty is 8 points for a flat tire, tires below the legal tread depth minimums, or any tire with visible steel or fabric. 3 points is the penalty associated with an

"underinflated" tire.
